Grid Connection Devices with a high output can inﬂuence the energy quality of the grid due to

their current consumption.

This may affect a number of device types in terms of:

connection restrictions

criteria regarding maximum permissible grid impedance

criteria regarding the minimum required short-circuit power

both at the interface with the public grid

See technical data

In this case, the operator or the person using the device should check whether or not the device is allowed to be connected, where appropriate through discussion with the power supply company.

IMPORTANT! Ensure secure grounding of the grid connection!

face guard featuring a regulation-compliant filter Wearing regulation-compliant protective goggles with side protection behind

the face guard Wearing rigid, wet-insulating footwear

Protecting hands with appropriate gloves (featuring electrical insulation and

thermal protection) Wearing ear protection to reduce noise exposure and protect against injury

Danger from toxic gases and vapors

Keep persons, especially children, away during the operation of the devices and during the welding process. If persons are in the vicinity, however:

Instruct them about all hazards (blinding hazard due to arcs, risk of injury

from ﬂying sparks, welding fumes hazardous to health, noise exposure, possible hazard due to grid current or welding current, etc.) Provide suitable protective equipment or

Construct suitable protective walls and curtains.

The fumes produced during welding contain toxic gases and vapors.

Welding fumes contain substances that cause cancer, as stated in monograph 118 from the International Agency for Research on Cancer.

Page 11

Use at-source extraction source and a room extraction system. If possible, use a welding torch with an integrated extraction device.

Keep your head out of the welding fumes and gases.

Take the following precautionary measures for fumes and harmful gases:

Do not breathe them in.

Extract them from the work area using appropriate equipment.

Ensure that there is a sufficient supply of fresh air. Ensure that there is a ventilation ﬂow rate of at least 20 m³ per hour.

Use a welding helmet with air supply if there is insufficient ventilation.

If there is uncertainty as to whether the extraction capacity is sufficient, compare the measured toxic emission values against the permissible limit values.

The following components are factors that determine how toxic the welding fumes are:

The metals used for the workpiece

Electrodes

Coatings

Cleaning agents, degreasers, and the like

The welding process used

Consult the corresponding material safety data sheets and manufacturer's instructions for the components listed above.

Recommendations for exposure scenarios, risk management measures and identifying working conditions can be found on the European Welding Association website under Health & Safety (https://european-welding.org).

EN-US

Danger from Flying Sparks

Keep ﬂammable vapors (such as solvent vapors) out of the arc radiation range.

When no welding is taking place, close the valve of the shielding gas cylinder or the main gas supply.

Flying sparks can cause fires and explosions.

Never undertake welding near ﬂammable materials.

Flammable materials must be kept at least 11 meters (36 ft. 1.07 in.) from the arc or protected with a certified cover.

Keep suitable, tested fire extinguishers on hand.

Sparks and pieces of hot metal may also get into surrounding areas through small cracks and openings. Take appropriate measures to ensure that there is no risk of injury or fire.

Do not undertake welding in areas at risk of fire and explosion, or on sealed tanks, drums, or pipes if these have not been prepared in accordance with corresponding national and international standards.

Do not undertake welding on containers in which gases, fuels, mineral oils, and the like are/were stored. Residues pose a risk of explosion.

Risks from grid current and welding current

An electric shock can be fatal.

Do not touch voltage-carrying parts inside or outside the device.

Page 12

During MIG/MAG welding and TIG welding, the welding wire, the wirespool, the feed rollers, as well as all pieces of metal that are in contact with the welding wire, are live.

Always place the wirefeeder on a sufficiently insulated base or use a suitable insulating wirefeeder holder.

Ensure suitable personal protection with dry temporary backing or cover with sufficient insulation against the ground potential. The temporary backing or cover must completely cover the entire area between the body and the ground potential.

All cables and leads must be secured, undamaged, insulated, and adequately dimensioned. Replace loose connections and scorched, damaged, or inadequately dimensioned cables and leads immediately. Before every use, check power connections for secure fit by hand. In the case of power cables with bayonet connectors, turn the power cable by at least 180° around the longitudinal axis and pretension.

Do not wrap cables or leads around your body or parts of the body.

Concerning the electrode (rod electrode, tungsten electrode, welding wire, etc.)

Never immerse it in liquids to cool it

Never touch it when the power source is switched on.

The open circuit voltage of a welding system may double, for example, between the electrodes of two welding systems. Touching the potentials of both electrodes at the same time may be life-threatening in some cases.

Have the grid and device supply lead regularly inspected by an electrician to ensure that the ground conductor is functioning properly.

Protection class I devices require a grid with a ground conductor and a connector system with ground conductor contact for proper operation.

Operation of the device on a grid without a ground conductor and on a socket without a ground conductor contact is only permitted if all national regulations for protective separation are observed. Otherwise, this is considered gross negligence. The manufacturer accepts no liability for any damage resulting from improper use.

Use suitable equipment to ensure that the workpiece is sufficiently grounded if necessary.

Switch off unused devices.

When working at elevated heights, wear a safety harness to prevent falls.

Before working on the device, switch off the device and remove the grid plug.

Secure the device to prevent the grid plug from being connected and switched on again by applying a clearly legible and understandable warning sign.

After opening the device:

Discharge all electrically charged components

Ensure that all components are disconnected from the power supply.

If work is needed on voltage-carrying parts, bring in a second person who will switch off the main switch at the correct time.

Page 13

Stray welding currents

If the following instructions are not observed, stray welding currents may occur, which pose a risk of the following:

Fire

Overheating of parts connected to the workpiece

Irreparable damage to ground conductors

Damage to the device and other electrical equipment

Ensure that the workpiece clamp is securely connected to the workpiece.

Secure the workpiece clamp as close to the spot to be welded as possible.

Position the device with sufficient insulation against electrically conductive environments, e.g., insulation against electrically conductive ﬂoors or electrically conductive mounts.

Observe the following when using power distribution boards, twin-head mounts, etc.: Even the electrode of the welding torch/electrode holder not in use carries electric potential. Ensure that there is sufficient insulation when the unused welding torch/electrode holder is stored.

In automated MIG/MAG applications, only guide the wire electrode from the welding wire drum, large spool, or wirespool to the wirefeeder with insulation.

Grid power supply

1. If electromagnetic interference occurs despite a grid connection that

complies with regulations, take additional measures (e.g., use a suitable grid filter).

Welding power-leads

2. Keep them as short as possible

Route them close together (also to avoid EMF problems)

Route them far from other lines

Page 14

Equipotential bonding

Workpiece grounding

4. If necessary, establish grounding using suitable capacitors.

Shield, if necessary

5. Shield other devices in the vicinity

Shield the entire welding installation

EMF measures Electromagnetic fields may cause health problems that are not yet known:

Effects on the health of persons close by, e.g., those with pacemakers and

hearing aids Persons with pacemakers must seek advice from their doctor before staying

in the immediate vicinity of the device and the welding process Keep distances between welding power-leads and the head/torso of the

welder as great as possible for safety reasons Do not carry welding power-leads and hosepacks over your shoulder or wrap

them around your body or body parts

Particular hazard areas

Keep hands, hair, loose clothing, and tools away from moving parts, such as:

Fans

Gears

Rollers

Shafts

Wirespools and welding wires

Do not reach into rotating gears of the wire drive or into rotating drive parts.

Covers and side panels must only be opened/removed during maintenance and repair work.

During operation

Ensure that all covers are closed, and all side parts have been mounted prop-

erly. Keep all covers and side parts closed.

The protrusion of welding wire from the welding torch represents a high risk of injury (cuts to the hand, facial and eye injuries, etc.).

Therefore, always hold the welding torch away from the body (devices with wirefeeder) and use suitable protective goggles.

Do not touch the workpiece during or after welding – risk of burns.

Slag may ﬂy off cooling workpieces. Therefore, also wear regulation-compliant protective equipment when reworking workpieces and ensure that other persons are sufficiently protected.

Leave the welding torch and other parts with a high operating temperature to cool before working on them.

Special regulations apply in areas at risk of fire or explosion – follow the appropriate national and international regulations.

Power sources for work in areas with increased electrical hazard (e.g., boilers) must be labeled with the symbol (Safety). However, the power source may not be located in such areas.

Risk of scalding due to leaking coolant. Switch off the cooling unit before disconnecting connections for the coolant supply or return.

Page 15

When handling coolant, observe the information on the coolant safety data sheet. The coolant safety data sheet can be obtained from your service center or via the manufacturer's website.

Only use suitable load-carrying equipment from the manufacturer to transport devices by crane.

Attach chains or ropes to all designated attachments of the suitable load-

carrying equipment. Chains or ropes must be the smallest angle possible from vertical.

Remove gas cylinder and wirefeeder (MIG/MAG and TIG devices).

In the event of crane attachment of the wirefeeder during welding, always use a suitable, insulating wirefeeder hoisting attachment (MIG/MAG and TIG devices).

If the device is equipped with a carrier belt or handle, then this is used exclusively for transport by hand. The carrier belt is not suitable for transport by crane, counterbalanced lift truck, or other mechanical lifting tools.

All lifting equipment (belts, buckles, chains, etc.), which is used in association with the device or its components, must be checked regularly (e.g., for mechanical damage, corrosion, or changes due to other environmental inﬂuences). The test interval and scope must at least comply with the respective valid national standards and guidelines.

There is a risk of colorless, odorless shielding gas escaping without notice if an adapter is used for the shielding gas connection. Use suitable Teﬂon tape to seal the thread of the shielding gas connection adapter on the device side before installation.

EN-US

Requirement for the shielding gas

Danger from Shielding Gas Cylinders

Especially with ring lines, contaminated shielding gas can cause damage to equipment and reduce welding quality. Meet the following requirements regarding shielding gas quality:

Solid particle size < 40 µm

Pressure condensation point < -20 °C

Max. oil content < 25 mg/m³

Use filters if necessary.

Shielding gas cylinders contain compressed gas and may explode if damaged. Shielding gas cylinders are an integral part of the welding equipment, so they must be handled very carefully.

Protect shielding gas cylinders with compressed gas from excessive heat, mechanical impact, slag, open ﬂames, sparks, and arcs.

Mount the shielding gas cylinders vertically and secure them in accordance with instructions so they cannot fall over.

Keep shielding gas cylinders away from welding or other electrical circuits.

Never hang a welding torch on a shielding gas cylinder.

Never touch a shielding gas cylinder with an electrode.

Risk of explosion: Never weld on a compressed shielding gas cylinder.

Always use suitable shielding gas cylinders for the application in question and the correct matching accessories (controller, hoses, and fittings, etc.) Only use shielding gas cylinders and accessories that are in good condition.

Page 16

If a valve on a shielding gas cylinder is open, turn your face away from the outlet.

When no welding is taking place, close the valve of the shielding gas cylinder.

Leave the cap on the valve of the shielding gas cylinder when the cylinder is not connected.

Follow the manufacturer's instructions and applicable national and international provisions for shielding gas cylinders and accessories.

Danger Posed by Shielding Gas Leak

Safety Measures at the Setup Location and During Transport

Risk of asphyxiation due to uncontrolled shielding gas leak

Shielding gas is colorless and odorless and may suppress the oxygen in the ambient air in the event of leakage.

Ensure there is a sufficient supply of fresh air with a ventilation ﬂow rate of

at least 20 m³ per hour. Please observe the safety and maintenance information for the shielding gas

cylinder or the main gas supply. When no welding is taking place, close the valve of the shielding gas cylinder

or the main gas supply. Always check the shielding gas cylinder or main gas supply for uncontrolled

gas leakage before each start-up.

Mechanical requirements

The following mechanical requirements must be met in order to achieve a stable and reproducible TWIN welding process:

Precise welding torch guidance by robots or single-purpose machines (e.g.

longitudinal chassis) Exact weld preparation

Low component tolerances

EN-US

Electrical Requirements

Software requirements

Dimensioning of the robot

Measures to increase system availability

Cables of the welding circuit laid correctly

The max. inductance in the welding circuit must not exceed 35 µH.

Software version min. 2.2.3 (TWIN Push) or min. 3.2.30 (TWIN Push/Pull,

CMT) Both power sources must have the same software status.

The IP addresses must be set correctly on the power sources.

Observe the following points during the dimensioning of the robot:

Payload and rated torques of the robot must be designed for the weight of

all mounted system components: welding torch, hose package, wire feed, robot fixtures, etc. The CrashBox must be designed accordingly.

Wirefeeding hoses must be laid in such a way that the movements of the ro-

bot and the wirefeed are not inﬂuenced (e.g. laying the wirefeeding hoses via balancers in the robot cell).

The use of the following devices is recommended in order to increase the system availability:

Robacta TSS /i

welding torch service station

Robacta Reamer TWIN/Single

mechanical torch cleaning device, can be used for all base materials such as steel, aluminum, CrNi steels, copper, etc.

Robacta TC 2000 TWIN

electromagnetic torch cleaning device for ferromagnetic base materials

TXi TWIN

torch body change system (only for TWIN Push welding systems)

Ground connection

Use a separate return lead cable for each power source:

A - Separate return lead cable B - Shared return lead cable, grounding bridge

C - Return lead cable laid in loops D - Return lead cable coiled

Page 27

NOTE!

When establishing a ground earth connection, observe the following points:

Use a separate return lead cable for each power source - A

▶

Keep positive cables and return lead cables as close together as possible for

▶

as long as possible Physically separate the welding circuits of individual power sources

▶

Do not route several return lead cables in parallel;

▶

if parallel routing cannot be avoided, keep a minimum distance of 30 cm between the welding circuits Keep the return lead cables as short as possible and use cables with a large

▶

cross-section Do not cross over return lead cables

▶

Avoid ferromagnetic materials between the return lead cables and the inter-

▶

connecting hosepack Do not wind up long return lead cables - coil effect! - C

▶

Lay long return lead cables in loops - D Do not route return lead cables in iron pipes, metal cable trays, or along steel

▶

beams, avoid cable ducts; (routing positive cables and return lead cables together in an iron pipe does not cause any problems) If several return lead cables are being used, separate the grounding points

▶

on the component as far as possible and do not allow crossed current paths between the individual arcs. Use compensated interconnecting hosepacks (interconnecting hosepacks

▶

with integrated return lead cable)

Operating Principle

Lead power source and trail power source

Two wire electrodes (4) and (5) are welded in a weld pool in a shielding gas

environment. The welding process is carried out via two independent power sources (1) and

(2). The power sources are synchronized by the TWIN Controller. The wirefeed is carried out via a wirefeeder (3) with two drive units.

The two wire electrodes are brought together in the welding torch so that

there are two independent welding potentials (6).

In the TWIN welding process, the two power sources are referred to as the lead power source and trail power source.

The lead power source is defined by the welding direction.

During pulsed-arc welding, the lead power source stipulates the frequency

for the trail power source. When viewed in the direction of welding, the wire electrode of the lead power

source is the front wire electrode. If the welding direction changes and the torch position remains the same,

then the trail power source becomes the lead power source. The robot controls define lead and trail using 2 bits. Depending on the result

of this process, lead or trail will also be displayed on the power source.

CrashBox

General The CrashBox is a protection device for the torch body and the torch body coup-

ling. In the event of a collision, the CrashBox emits a signal to the robot controls, which causes the robot controls to stop the robot immediately. Due to the welding torch holder of the CrashBox, the welding torch and the installed system components are protected from damage in the event of a collision.

The magnetic coupling of the CrashBox allows for a low-force deﬂection with large deﬂection path in the event of a crash.

The clamp system is used to hold the TWIN welding torch for TWIN Push systems. With the index disk corresponding to the torch body curvature, the clamp system positions the welding torch so that the TCP is in the 6th axis.

Note on the correct operation of CrashBoxes

Note on the repair of CrashBoxes

Example: CrashBox /i with clamp system, installed on the robot arm (TWIN Push)

A robot-specific, insulating robot ﬂange is required for the installation of the CrashBox.

NOTE!

To avoid damage to the welding torch or the torch hosepack, or to prevent false triggering of the CrashBox, consider the following points:

Avoid strong accelerations and maximum speeds during robot movements.

▶

Ensure the free movement of the torch hosepack during all robot move-

▶

ments; The torch hosepack must not tighten in any position and thus exert a strain on the CrashBox. The torch hosepack must not whip around or get stuck when moving.

▶

If possible, check all movement situations with Fronius system components

▶

in a simulation as early as the concept phase.

NOTE!

Only complete CrashBoxes should be sent for repair!

Incomplete CrashBoxes (e.g. without magnetic ring) cannot be checked in the course of a repair.

TWIN-MTB Single adapter

(A) hosepack side, (B) torch body side, 1 = welding line 1, 2 = welding line 2

With the aid of the TWIN-MTB Single adapter, the TWIN welding system can be operated with a single torch body. The adapter combines gas and compressed air lines as well as the wirefeeding lines of both welding lines. The coolant lines are run and the current paths of both welding lines are merged into one.

EN-US

The weld line is defined by inserting the inner liner into the respective wire inlet on the TWIN-MTB Single adapter.

If there is a torch body change system in the welding system, the changeover from the TWIN welding torch to the single welding torch and vice versa can also be automated.

NOTE!

When operating a single welding torch on a TWIN welding system, observe the maximum welding current and the duty cycle (D.C.) of the single welding torch.

quence for CMT TWIN

L = Lead wire electrode, T = Trail wire electrode

Both wire electrodes move towards the workpiece

Both wire electrodes make contact with the workpiece

The lead wire electrode starts the welding process, the trail wire electrode

moves away from the workpiece and waits for the start signal of the lead wire electrode = welding start delay As soon as the trail wire electrode receives the start signal, it also starts the

welding process

A CMT TWIN welding process requires a WF 60i TWIN Drive unit and a wire buffer.

In conjunction with a WF 60i TWIN Drive unit, all TWIN characteristics ignite according to the above sequence.

TWIN operating mode

The robot controls use the signals "Operating mode TWIN System Bit 0" and "Operating mode TWIN System Bit 1" to define

the lead and trail process line in TWIN mode

the active process line in single wire mode

TWIN Characteristics

General Only PMC TWIN characteristics with the following properties are available for

the TWIN welding process:

Universal

Characteristic packages for conventional welding tasks

The characteristics are optimized for a wide range of applications in synchronized TWIN welding. The pulse synchronization ratio and the lead/trail phase shift are supported, provided that a TWIN universal characteristic is in use at both power sources.

Multi arc

Characteristic packages for conventional welding tasks

The characteristics are optimized for synchronized TWIN welding with multiple welding systems and reduce the mutual inﬂuence of multiple power sources. The pulse synchronization ratio and the lead/trail phase shift are supported, provided that a TWIN multi arc characteristic is in use at both power sources.

PCS (Pulse Controlled Sprayarc) These characteristics combine the advantages of pulse and standard arcs in one characteristic: a concentrated pulse arc passes directly into a short spray arc; the intermediate arc is blanked out. The characteristic curve does not support synchronization.

EN-US

Overlay welding

The characteristics are optimized for synchronized TWIN overlay welding.

A special current profile ensures a wide arc with optimized weld ﬂow and low dilution. The pulse synchronization ratio and the lead/trail phase shift are supported, provided that a TWIN Universal or a TWIN multi arc characteristic is in use at both power sources.

Root

Characteristics for root passes

The characteristics are optimized for CMT welding at the lead and trail electrode.

IMPORTANT! The same TWIN characteristic must be selected on both process lines.

Prerequisites for using a PMC TWIN characteristic:

Pulse welding package on both power sources

Both power sources must be connected to the TWIN Controller.

Time coordination of the power sources

The PMC processes of the two process lines are synchronized with each other. This ensures a stable, consistent tandem welding process. The relative position of the pulses/droplet detachment is stored in the characteristic but can also be freely selected.

Significantly different outputs at lead and trail wire electrode

The TPS/i TWIN welding system enables significantly different outputs or wire speeds to be used, even during synchronized PMC tandem processes. A significantly higher output is usually selected at the lead wire electrode than at the trail wire electrode. This results in:

Targeted heat input

The cold parent material melts well

Exact recording of the root pass

Trail wire electrode fills up the weld pool

Extension of the gas release time (reduced proneness to porosity)

High welding speed

IMPORTANT! Only PMC TWIN characteristics synchronize. For synchronization, a TWIN universal, a TWIN multi arc, or a TWIN cladding characteristic must be used on the lead and trail wire electrode respectively.

Welding current time curves and schematic representation of the material transition

PCS TWIN characteristics are predominantly used in order to weld with a modified spray arc at the lead wire electrode and a pulsed arc at the trail wire electrode. Pulse synchronization is not activated when a PCS TWIN characteristic is used.

Advantages:

High penetration by the standard arc of the lead wire electrode

Large seam cross sections possible

Large difference in the wire feeding speeds possible

Visually pleasing weld seams due to the pulsed arc of the trail wire electrode

NOTE!

In the TWIN process PCS TWIN / PCS TWIN, only weld the lead wire electrode in the spray arc.

Page 64

PMC TWIN / CMT TWIN

Schematic representation of the material transition

Advantages:

Deep penetration of the lead wire electrode

High deposition rate at the lead wire electrode

Very good seam filling due to the trail wire electrode

High process stability

The TWIN welding process PMC TWIN / CMT TWIN can be used for both welding directions.

CMT TWIN / CMT TWIN

NOTE!

In the TWIN welding process PMC TWIN / CMT TWIN, optimum welding results are achieved with a contact tip tilt angle of 8°.

Schematic representation of the material transition

In this process variant, the same characteristics are used for both wire electrodes. The arc of the lead wire electrode is shorter than that of the trail wire electrode. This results in a higher output on the lead wire electrode. The arc of the trail wire electrode is specifically matched to the weld pool.

Single wire welding

In single wire welding, a signal is emitted by the robot controls, meaning that only one power source welds. Depending on the torch position or restricted position of the weld, single wire welding can be carried out by the lead or trail power source. The second power source pauses.

NOTE!

In order to ensure a full gas shield during single wire welding with TWIN welding torches, the solenoid valve for the pausing power source is open.

The solenoid valve is controlled via the power source.

PMC, Pulse, LSC, Standard, and CMT arcs are possible during single wire welding as long as the appropriate Welding Package is available on the power source. It is not necessary to change the welding torch.

Single wire welding is used in a TWIN welding system:

When welding very tight radii

When welding in difficult positions and restricted positions

To fill up end-craters

If there has been a switch to a single welding torch on the welding torch

When this function is activated, the ignition point of the trail arc always depends on the present phase of the lead arc. The start parameters of the trail arc are automatically adapted to the prevailing conditions of the lead arc. The trail arc starts without contact in TWIN Push systems and with a synchronized SFI (spatter-free ignition) in TWIN Push/Pull systems. As a result, the start of the trail arc is significantly smoother and failed ignitions are avoided or their number reduced.

Trail ignition delay *

Automatic (auto) mode implements an optimum ignition delay.

Page 68

When set manually, an ignition delay of 0–2 seconds can be set. The start of the trail arc is synchronized.

The function can be deactivated. In this case, the trail arc is ignited immediately and is not synchronized.

Information on the power source display

Pulse synchronization ratio

Adjustment range: auto, 1/1, 1/2, 1/3 Factory setting: auto

Only active if the same PMC TWIN characteristic is set for both wire electrodes.

The pulse synchronization ratio enables both process lines to be operated with significantly different wire speeds. In the case of greater differences in output, the pulse frequency is adjusted in such a way that it differs between lead and trail by an integral multiple. Only every second or every third pulse is then executed for the trail arc, for example.

The characteristic for automatic ("auto") mode contains an optimum frequency ratio based on the wire speed values for both process lines. The wire speed can be set separately for each process line.

When setting the frequency ratio manually, the value can be set on both power sources independently. The value set on the trail power source is applied to the process.

1/1 Both arcs work with the same pulse frequency. The number of droplets

per time unit is identical in both process lines.

1/2 The trail arc works with half the pulse frequency of the lead arc. Droplet

detachment only takes place at the trail arc with every other pulse.

1/3 The trail arc works with a third of the pulse frequency of the lead arc.

Droplet detachment only takes place at the trail arc every third pulse.

Information on the power source display

Page 69

Lead/trail phase shift

Adjustment range: auto, 0–95% Factory setting: auto

Only active if the same PMC TWIN characteristic is set for both wire electrodes.

Lead/trail phase shift enables the time of droplet detachment to be freely selected for the trail arc. As the trail droplet detachment does not have to take place in the quiescent current phase of the lead arc, an arc blow between the two arcs can be counteracted.

In automatic ("auto") mode, the characteristics contain the optimum location of the two main current phases in relation to one another and this can change along the characteristic.

When set manually, the phase shift can be set between the two pulses as a percentage of the period duration. The adjustment range of 0–95% corresponds to a phase shift of 0–342°.

0% Synchronous mode – no phase shift between the two process lines, lead

and trail droplet detachments take place at the same time

50% Asynchronous mode – 180° phase shift, each droplet detachment takes

place in the quiescent current phase of the other arc.

TWIN SynchroPulse

SynchroPulse welding

TWIN SynchroPulse

SynchroPulse is available for all process (Standard / Pulse / LSC / PMC). The cyclic change of the welding power between two operating points with SynchroPulse achieves a finely rippled weld appearance and a non-continuous heat input.

From the firmware version "official_TPSi_4.0.0-xxxxx.xxxxx.ffw", SynchroPulse can also be used in a TWIN welding process.

For TWIN SynchroPulse, the SynchroPulse parameters Frequency and DutyCycle (high) are set and specified at the lead power source. The settings for Frequency and DutyCycle (high) at the trail power source have no effect.

The remaining welding parameters can be selected differently on both process lines.

Function of the gas-test, wirereturn, and wirethreading buttons

Operating status LED

Lights up green when the device is ready for operation

Gas-test button

After pressing the gas-test button, gas is released for 30 s. Pressing the button again will end the process prematurely.

Wire-return button

There are two options available for retracting the wire electrode:

Option 1 Withdraw wire electrode at the preset wire return speed:

Press and hold the wire-return button

After pressing the wire-return button, the wire electrode is retracted by

1 mm (0.039 in.) After a brief pause, the wirefeeder continues retracting the wire electrode –

if the wire-return button is kept pressed down, then the speed increases with each further second by 10 m/min (393.70 ipm) until the preset wire-return speed is reached

Option 2 Withdraw wire electrode in 1 mm steps (0.039 in. steps)

Always press (touch) the wire-return button for less than 1 second

NOTE!

Only retract the wire electrode a small amount at a time, to avoid the wire electrode becoming entangled on the wirespool during retraction.

NOTE!

If there is a ground earth connection with the contact tip, before the wire-return button is pressed, the wire electrode is retracted by pressing the wire-return button until the wire electrode is short-circuit-free—however, this must not exceed 10 mm (0.39 in.) each time the button is pressed.

If the wire electrode needs to be retracted further, press the wire-return button again.

Page 84

Wire-threading button

There are two options available for the wire threading:

Option 1 Thread the wire electrode at the preset feeder inching speed:

Press and hold the wire-threading button

After pressing the wire-threading button, the wire electrode will be threaded

in by 1 mm (0.039 in.) After a brief pause, the wirefeeder continues threading in the wire electrode

– if the wire-threading button is kept pressed down, then the speed increases with each further second by 10 m/min (393.70 ipm) until the preset feeder inching speed is reached If the wire electrode meets a ground earth connection, then the wirefeeding

is stopped and the wire electrode is retracted again by 1 mm (0.039 in.)

Option 2 Thread the wire electrode in 1 mm steps (0.039 in. steps)

Always press (touch) the wire-threading button for less than 1 second

If the wire electrode meets a ground earth connection, then the wirefeeding

is stopped and the wire electrode is retracted again by 1 mm (0.039 in.)

NOTE!

If there is a ground earth connection with the contact tip, before the wirethreading button is pressed, the wire electrode is retracted by pressing the wirethreading button until the wire electrode is short-circuit-free—however, this must not exceed 10 mm (0.39 in.) each time the button is pressed.

If after the 10 mm (0.39 in.) wire retraction there is still a ground earth connection with the contact tip, then when the wire-threading button is pressed again, the wire electrode is retracted again by a maximum of 10 mm (0.39 in.). The process is repeated until there is no longer any ground earth connection with the contact tip.

Insulated Guiding of the Wire Electrode to the Wirefeeder

WARNING!

Risk of injury and property damage, as well as impairment of the welding result, due to ground fault or earth leakage of a non-insulated wire electrode.

In automated applications, only guide the wire electrode from the welding

▶

wire drum, large spool or wirespool to the wirefeeder with insulation (for example using a wirefeeding hose).

A ground fault or earth leakage can be caused by:

a non-insulated, exposed wire electrode, that comes into contact with an

electrically conductive object during the welding process a lack of insulation between the wire electrode and the grounded housing

limit of a robot cell chafed wirefeeding hose and therefore bare wire electrodes

In order to avoid ground faults or earth leakage:

use wirefeeding hoses—for insulated guidance of the wire electrode to the

wirefeeder do not guide wirefeeding hoses over sharp edges in order to avoid chafing of

the wirefeeding hoses if necessary, use a hose holder or chafe protector

Couplings and drum covers for welding wire drums are also recommended in

order to ensure safe transport of the wire electrode
