The device is designed for use in industry and the workshop. The manufacturer accepts no responsibility for any damage caused through use in a domestic setting.

The manufacturer likewise accepts no liability for inadequate or incorrect results.

Environmental conditions

Obligations of the operator

Operation or storage of the device outside the stipulated area will be deemed as not in accordance with the intended purpose. The manufacturer shall not be held liable for any damage arising from such usage.

Ambient temperature range:

- during operation: -10 °C to + 40 °C (14 °F to 104 °F)

- during transport and storage: -20 °C to +55 °C (-4 °F to 131 °F)

Relative humidity:

- up to 50% at 40 °C (104 °F)

- up to 90% at 20 °C (68 °F)

The surrounding air must be free from dust, acids, corrosive gases or substances, etc. Can be used at altitudes of up to 2000 m (6561 ft. 8.16 in.)

The operator must only allow persons to work with the device who:

- are familiar with the fundamental instructions regarding safety at work and accident prevention and have been instructed in how to use the device

- have read and understood these operating instructions, especially the section "safety rules", and have confirmed as much with their signatures

- are trained to produce the required results.

Checks must be carried out at regular intervals to ensure that operators are working in a safety-conscious manner.

Obligations of personnel

Mains connection Devices with a higher rating may affect the energy quality of the mains due to their cur-

Before using the device, all persons instructed to do so undertake:

- to observe the basic instructions regarding safety at work and accident prevention

- to read these operating instructions, especially the "Safety rules" section and sign to confirm that they have understood them and will follow them.

Before leaving the workplace, ensure that people or property cannot come to any harm in your absence.

rent consumption.

This may affect a number device types in terms of:

- Connection restrictions

Criteria with regard to the maximum permissible mains impedance

Criteria with regard to the minimum short-circuit power requirement

at the interface with the public grid

see "Technical data"

In this case, the plant operator or the person using the device should check whether the device may be connected, where appropriate by discussing the matter with the power supply company.

IMPORTANT! Ensure that the mains connection is earthed properly

Residual current protective device

Protecting yourself and others

Local regulations and national guidelines may require a residual current protective device when connecting equipment to the public grid. The type of residual current protective device recommended by the manufacturer for the equipment is indicated in the technical data.

Anyone working with the device exposes themselves to numerous risks, e.g.

- flying sparks and hot pieces of metal

- Arc radiation, which can damage eyes and skin

- Hazardous electromagnetic fields, which can endanger the lives of those using cardiac pacemakers

- Risk of electrocution from mains current and welding current

- Greater noise pollution

- Harmful welding fumes and gases

Suitable protective clothing must be worn when working with the device. The protective clothing must have the following properties:

- Flame-resistant

- Insulating and dry

- Covers the whole body, is undamaged and in good condition

- Safety helmet

- Trousers with no turn-ups

Protective clothing refers to a variety of different items. Operators should:

- Protect eyes and face from UV rays, heat and sparks using a protective visor and regulation filter

- Wear regulation protective goggles with side protection behind the protective visor

- Wear stout footwear that provides insulation even in wet conditions

- Protect the hands with suitable gloves (electrically insulated and providing protection against heat)

- Wear ear protection to reduce the harmful effects of noise and to prevent injury

Noise emission values

Keep all persons, especially children, out of the working area while any devices are in operation or welding is in progress. If, however, there are people in the vicinity:

- Make them aware of all the dangers (risk of dazzling by the arc, injury from flying sparks, harmful welding fumes, noise, possible risks from mains current and welding current, etc.)

- Provide suitable protective equipment

- Alternatively, erect suitable safety screens/curtains.

The device generates a maximum sound power level of <80 dB(A) (ref. 1pW) when idling and in the cooling phase following operation at the maximum permissible operating point under maximum rated load conditions according to EN 60974-1.

It is not possible to provide a workplace-related emission value during welding (or cutting) as this is influenced by both the process and the environment. All manner of different welding parameters come into play, including the welding process (MIG/MAG, TIG welding), the type of power selected (DC or AC), the power range, the type of weld metal, the resonance characteristics of the workpiece, the workplace environment, etc.

Danger from toxic gases and vapours

The fumes produced during welding contain harmful gases and vapours.

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

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

Keep your face away from welding fumes and gases.

Fumes and hazardous gases

- must not be breathed in

- must be extracted from the working area using appropriate methods.

Ensure an adequate supply of fresh air. Ensure that there is a ventilation rate of at least 20 m³ per hour at all times.

Otherwise, a welding helmet with an air supply must be worn.

If there is any doubt about whether the extraction capacity is sufficient, the measured toxic emission values should be compared with the permissible limit values.

The following components are responsible, amongst other things, for the degree of toxicity of welding fumes:

- Metals used for the workpiece

- Electrodes

- Coatings

- Cleaners, degreasers, etc.

- Welding process used

Danger from flying sparks

The relevant material safety data sheets and manufacturer's specifications for the listed components should therefore be studied carefully.

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

Flammable vapours (e.g. solvent fumes) should be kept away from the arc's radiation area.

Close the shielding gas cylinder valve or main gas supply if no welding is taking place.

Flying sparks may cause fires or explosions.

Never weld close to flammable materials.

Flammable materials must be at least 11 metres (36 ft. 1.07 in.) away from the arc, or alternatively covered with an approved cover.

A suitable, tested fire extinguisher must be available and ready for use.

Sparks and pieces of hot metal may also get into adjacent areas through small gaps or openings. Take appropriate precautions to prevent any danger of injury or fire.

Welding must not be performed in areas that are subject to fire or explosion or near sealed tanks, vessels or pipes unless these have been prepared in accordance with the relevant national and international standards.

Do not carry out welding on containers that are being or have been used to store gases, propellants, mineral oils or similar products. Residues pose an explosive hazard.

Risks from mains current and welding current

An electric shock is potentially life threatening and can be fatal.

Do not touch live parts either inside or outside the device.

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

Always set the wirefeeder up on a sufficiently insulated surface or use a suitable, insulated wirefeeder holder.

Make sure that you and others are protected with an adequately insulated, dry temporary backing or cover for the earth or ground potential. This temporary backing or cover must extend over the entire area between the body and the earth or 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. Use the handle to ensure the power connections are tight before every use. In the case of power cables with a bayonet connector, rotate the power cable around the longitudinal axis by at least 180° and pre-load.

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

The electrode (rod electrode, tungsten electrode, welding wire, etc.) must

- never be immersed in liquid for cooling

- Never touch the electrode when the power source is switched on.

Double the open circuit voltage of a power source can occur between the welding electrodes of two power sources. Touching the potentials of both electrodes at the same time may be fatal under certain circumstances.

Arrange for the mains cable to be checked regularly by a qualified electrician to ensure the ground conductor is functioning properly.

The device must only be operated on a mains supply with a ground conductor and a socket with a ground conductor contact.

Operating the device on a grid without a ground conductor and in a socket without a ground conductor contact will be deemed gross negligence. The manufacturer shall not be held liable for any damage arising from such usage.

If necessary, provide an adequate earth connection for the workpiece.

Switch off unused devices.

Wear a safety harness if working at height.

Before working on the device, switch it off and pull out the mains plug.

Attach a clearly legible and easy-to-understand warning sign to the device to prevent anyone from plugging the mains plug back in and switching it on again.

After opening the device:

- Discharge all live components

- Ensure that all components in the device are de-energised

If work on live parts is required, appoint a second person to switch off the main switch at the right moment.

Meandering welding currents

EMC Device Classifications

If the following instructions are ignored, meandering welding currents can develop with the following consequences:

- Fire hazard

- Overheating of parts connected to the workpiece

- Irreparable damage to ground conductors

- Damage to device and other electrical equipment

Ensure that the workpiece is held securely by the workpiece clamp.

Attach the workpiece clamp as close as possible to the area that is to be welded.

If the floor is electrically conductive, the device must be set up with sufficient insulating material to insulate it from the floor.

If distribution boards, twin-head mounts, etc., are being used, note the following: The electrode of the welding torch / electrode holder that is not used is also live. Make sure that the welding torch / electrode holder that is not used is kept sufficiently insulated.

In the case of automated MIG/MAG applications, ensure that only an insulated wire electrode is routed from the welding wire drum, large wirefeeder spool or wirespool to the wire-feed unit.

Devices in emission class A:

- Are only designed for use in industrial settings

- Can cause line-bound and radiated interference in other areas

Devices in emission class B:

- Satisfy the emissions criteria for residential and industrial areas. This is also true for residential areas in which the energy is supplied from the public low-voltage mains.

EMC device classification as per the rating plate or technical data.

EMC measures In certain cases, even though a device complies with the standard limit values for emis-

sions, it may affect the application area for which it was designed (e.g. when there is sensitive equipment at the same location, or if the site where the device is installed is close to either radio or television receivers). If this is the case, then the operator is obliged to take appropriate action to rectify the situation.

Check and evaluate the immunity to interference of nearby devices according to national and international regulations. Examples of equipment that may be susceptible to interference from the device include:

- Safety devices

- Power, signal and data transfer lines

- IT and telecommunications devices

- Measuring and calibrating devices

Supporting measures for avoidance of EMC problems:

1. Mains supply

- If electromagnetic interference arises despite correct mains connection, addi-

tional measures are necessary (e.g. use a suitable line filter).

2. Welding power leads

- must be kept as short as possible

- must run close together (to avoid EMF problems)

- must be kept well apart from other leads

3. Equipotential bonding

4. Earthing of the workpiece

- If necessary, establish an earth connection using suitable capacitors.

5. Shielding, if necessary

- Shield off other nearby devices

- Shield off entire welding installation

EMF measures Electromagnetic fields may pose as yet unknown risks to health:

- effects on the health of others in the vicinity, e.g. wearers of pacemakers and hearing aids

- wearers of pacemakers must seek advice from their doctor before approaching the device or any welding that is in progress

- for safety reasons, keep distances between the welding cables and the welder's head/torso as large as possible

- do not carry welding cables and hosepacks over the shoulders or wind them around any part of the body

Specific hazards Keep hands, hair, clothing and tools away from moving parts. For example:

- Fans

- Cogs

- Rollers

- Shafts

- Wirespools and welding wires

Do not reach into the rotating cogs of the wire drive or into rotating drive components.

Covers and side panels may only be opened/removed while maintenance or repair work is being carried out.

During operation

- Ensure that all covers are closed and all side panels are fitted properly.

- Keep all covers and side panels closed.

The welding wire emerging from the welding torch poses a high risk of injury (piercing of the hand, injuries to the face and eyes, etc.).

Therefore always keep the welding torch away from the body (devices with wire-feed unit) and wear suitable protective goggles.

Never touch the workpiece during or after welding - risk of burns.

Slag can jump off cooling workpieces. The specified protective equipment must therefore also be worn when reworking workpieces, and steps must be taken to ensure that other people are also adequately protected.

Welding torches and other parts with a high operating temperature must be allowed to cool down before handling.

Special provisions apply in areas at risk of fire or explosion - observe relevant national and international regulations.

Power sources for work in areas with increased electric risk (e.g. near boilers) must carry the "Safety" sign. However, the power source must not be located in such areas.

Risk of scalding from escaping coolant. Switch off cooling unit before disconnecting coolant flow or return lines.

Observe the information on the coolant safety data sheet when handling coolant. The coolant safety data sheet may be obtained from your service centre or downloaded from the manufacturer's website.

Use only suitable load-carrying equipment supplied by the manufacturer when transporting devices by crane.

- Hook chains and/or ropes onto all suspension points provided on the load-carrying equipment.

- Chains and ropes must be at the smallest angle possible to the vertical.

- Remove gas cylinder and wire-feed unit (MIG/MAG and TIG devices).

If the wire-feed unit is attached to a crane holder during welding, always use a suitable, insulated wirefeeder hoisting attachment (MIG/MAG and TIG devices).

If the device has a carrying strap or handle, this is intended solely for carrying by hand. The carrying strap is not to be used if transporting with a crane, counterbalanced lift truck or other mechanical hoist.

All lifting accessories (straps, handles, chains, etc.) used in connection with the device or its components must be tested regularly (e.g. for mechanical damage, corrosion or changes caused by other environmental factors). The testing interval and scope of testing must comply with applicable national standards and directives as a minimum.

Odourless and colourless shielding gas may escape unnoticed if an adapter is used for the shielding gas connection. Prior to assembly, seal the device-side thread of the adapter for the shielding gas connection using suitable Teflon tape.

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 gas under pressure and can explode if damaged. As the shielding gas cylinders are part of the welding equipment, they must be handled with the greatest of care.

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

Mount the shielding gas cylinders vertically and secure according to instructions to prevent them falling over.

Keep the shielding gas cylinders well away from any 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 attempt to weld a pressurised shielding gas cylinder.

Only use shielding gas cylinders suitable for the application in hand, along with the correct and appropriate accessories (regulator, hoses and fittings). Only use shielding gas cylinders and accessories that are in good condition.

Turn your face to one side when opening the valve of a shielding gas cylinder.

Close the shielding gas cylinder valve if no welding is taking place.

If the shielding gas cylinder is not connected, leave the valve cap in place on the cylinder.

The manufacturer's instructions must be observed as well as applicable national and international regulations for shielding gas cylinders and accessories.

Safety measures at the installation location and during transport

A device toppling over could easily kill someone. Place the device on a solid, level surface such that it remains stable

- The maximum permissible tilt angle is 10°.

Special regulations apply in rooms at risk of fire or explosion

- Observe relevant national and international regulations.

Use internal directives and checks to ensure that the workplace environment is always clean and clearly laid out.

Only set up and operate the device in accordance with the degree of protection shown on the rating plate.

When setting up the device, ensure there is an all-round clearance of 0.5 m (1 ft. 7.69 in.) to ensure that cooling air can flow in and out freely.

When transporting the device, observe the relevant national and local guidelines and accident prevention regulations. This applies especially to guidelines regarding the risks arising during transport.

Do not lift or transport operational devices. Switch off devices before transport or lifting.

Before transporting the device, allow coolant to drain completely and detach the following components:

- Wirefeeder

- Wirespool

- Shielding gas cylinder

Safety measures in normal operation

After transporting the device, the device must be visually inspected for damage before commissioning. Any damage must be repaired by trained service technicians before commissioning the device.

Only operate the device when all safety devices are fully functional. If the safety devices are not fully functional, there is a risk of

- injury or death to the operator or a third party

- damage to the device and other material assets belonging to the operator

- inefficient operation of the device

Any safety devices that are not functioning properly must be repaired before switching on the device.

Never bypass or disable safety devices.

Before switching on the device, ensure that no one is likely to be endangered.

Check the device at least once a week for obvious damage and proper functioning of safety devices.

Always fasten the shielding gas cylinder securely and remove it beforehand if the device is to be transported by crane.

Only the manufacturer's original coolant is suitable for use with our devices due to its properties (electrical conductibility, anti-freeze agent, material compatibility, flammability, etc.).

Only use suitable original coolant from the manufacturer.

Do not mix the manufacturer's original coolant with other coolants.

Only connect the manufacturer's system components to the cooling circuit.

The manufacturer accepts no liability for damage resulting from use of other system components or a different coolant. In addition, all warranty claims will be forfeited.

Cooling Liquid FCL 10/20 does not ignite. The ethanol-based coolant can ignite under certain conditions. Transport the coolant only in its original, sealed containers and keep well away from any sources of ignition.

Used coolant must be disposed of properly in accordance with the relevant national and international regulations. The coolant safety data sheet may be obtained from your service centre or downloaded from the manufacturer's website.

Check the coolant level before starting to weld, while the system is still cool.

General

Principle

TransPocket 2500 Comfort

Device concept The TP 2500 / 3500 Comfort power sources have connection sockets with bayonet fix-

ing, a powder-coated sheet steel housing with stainless steel runners and the controls are protected by plastic frames. The handle makes it easy to carry, both in-house or on-site.

The TransPocket (TP) 2500 Comfort and TransPocket (TP) 3500 Comfort power sources offer excellent ignition and welding properties, while being extremely lightweight with very small dimensions.

An electronic regulator adapts the power source characteristic to the electrode to be welded, and thus ensures a stable arc and optimum characteristic.

Application areas As compact units, the TP 2500 Comfort and TP 3500 Comfort power sources are espe-

cially well suited to portable use on building sites and for assembly work. But even when used as stationary units in workshops or industrial facilities, the machines are powerful and economical alternatives.

0 Soft, low-spatter arc

100 Harder, more stable arc

Working principle: At the instant of droplet transfer or when a short-circuit occurs, there is a temporary rise in the current intensity. To obtain a stable arc, the welding current is increased temporarily. If the rod electrode threatens to sink into the weld pool, this measure prevents the weld pool solidifying, as well as preventing more prolonged short-circuiting of the arc. This largely prevents the rod electrode from “sticking”.

Preparations 1. Plug the welding power-lead into the current socket, depending upon which type of

electrode is to be used, and latch it by turning it clockwise

2. Plug the grounding cable into the current socket, depending on which type of electrode is to be used, and latch it by turning it clockwise

3. Plug in the mains plug

(used with rutile and Cel processes)

Benefits:

- Improved ignition properties, even when using electrodes with poor ignition properties

- Better fusion of the base material during the start-up phase, meaning fewer cold-shut defects

- Largely prevents slag inclusions

Example of HotStart function

Mode of operation: The welding current is raised to a specific value for 1.5 seconds. This value is around 30% higher than the set welding current

Example: 90 A was set on the adjuster. The HotStart current is 90 A + 30% = 117 A

IMPORTANT! If the welding current is set to 192 A or higher, the HotStart current is limited to 250 A.

SoftStart function (used with basic process)

Anti-stick function

The SoftStart function is intended for basic electrodes. Ignition takes place at a low welding current. Once the arc is stable, the welding current continues to rise until it reaches the welding current command value.

Benefits:

- Improved ignition properties for electrodes that ignite at low welding currents

- Largely prevents slag inclusions

- Reduces welding spatter

Example of SoftStart function

As the arc becomes shorter, the welding voltage may drop so far that the rod electrode will tend to stick. The anti-stick function prevents the electrode from burning out. If the rod electrode begins to stick, the power source switches the welding current off after 1 second. After the rod electrode has been lifted off the workpiece, the welding operation can be continued without difficulty.

TIG Comfort Stop function

If there is a remote control unit connected to the remote control socket or if the TP09 wireless remote control unit is used, the symbol „EXT“ appears on the display:

All the possible welding parameter settings are made via the remote control unit.

The "TIG Comfort Stop" function (TCS) is only available with the TP 2500/3500 TIG power source. The TIG-Comfort-Stop function is deactivated as standard. Activating and setting the TIG Comfort Stop function is described in the "The Setup menu" section.

If the TIG Comfort Stop function is deactivated, end crater filling through current decrease or gas shielding of the end crater does not occur. To finish welding lift the torch away from the workpiece until the arc goes out.

To finish welding with activated TCS function, proceed as follows:

1. Welding

1. 2. 3. 4.

2. During welding, raise the welding torch

- The arc length is increased significantly

3. Lower the welding torch

- The arc length is decreased significantly

- This triggers the TIG Comfort Stop function

4. Keep the welding torch at the same height

- The welding current continuously decreases until it reaches the minimum weld-

ing current (10 A) (downslope)

- The minimum welding current is held constant for 0.2 seconds

- Arc goes out

5. Wait for the gas post-flow time to finish, and lift the torch off the workpiece

Downslope:

The downslope depends on the welding current selected and cannot be adjusted. The duration of the downslope between the following values must be extrapolated.

- Downslope with low welding current (10 A): 0.4 seconds

- Downslope with maximum welding current (250 A): 10 seconds

Gas post-flow time:

The gas post-flow time depends on the welding current selected and cannot be adjusted.

- Gas post-flow time with minimum welding current (10 A): 3 seconds

As the arc becomes shorter, the welding voltage may drop so far that the rod electrode will tend to “stick”. This may also cause “burn-out” of the rod electrode.

Electrode burn-out is prevented if the anti-stick function has been activated. If the rod electrode begins to stick, the power source immediately switches the welding current off. After the rod electrode has been detached from the workpiece, the welding operation can be continued without difficulty.

Voltage Reduction Device (VRD versions only)

General A Voltage Reduction Device (VRD) is an optional safety device for reducing the voltage.

As far as possible, VRD prevents output voltages at the current sockets that may pose a danger to persons.

Safety principle

Welding circuit resistance is greater than the minimum human body resistance (greater than or equal to 200 Ohm):

- VRD is active

- Open circuit voltage is limited to 12 V (otherwise 90 V)

- There is no risk in unintentionally touching both welding sockets at the same time

VRD is active

Welding circuit resistance is less than the minimum human body resistance (less than 200 Ohm):

- VRD is inactive

- Output voltage not restricted in order to ensure sufficient welding power

- Example: Start of welding

VRD is not active

IMPORTANT! Within 0.3 seconds of the end of welding

- VRD is active again

- The output voltage is limited to 12 V again

VRD display With VRD variants, the display indicates whether the VRD option is active or not:

VRD active VRD inactive

VRD active (VRD symbol on the display) VRD inactive (VRD symbol crossed out on the

display)

- The open-circuit voltage is limited to 12 V.

- No voltage limitation (e.g.: when welding) or

- VRD is defective
