Protecting yourself and others
Danger from toxic
gases and vapours
Persons involved with welding expose 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
Anyone working on the workpiece while welding is in progress must wear suitable protective clothing with 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.
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 or
- erect suitable safety screens/curtains.
The fumes produced during welding contain harmful gases and vapours.
Welding fumes contain substances that may, under certain circumstances,
cause birth defects or cancer.
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 with a ventilation rate of at least 20 m³/
hour.
Page 12
12
Danger from flying sparks
Risks from mains
current and welding current
Otherwise, a protective mask with an air supply must be worn.
Close the shielding gas cylinder valve or main gas supply if no welding is taking place.
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.
Amongst others, the following components are responsible for the degree of
toxicity of welding fumes:
- Metals used for the workpiece
- Electrodes
- Coatings
- Cleaners, degreasers, etc.
The relevant material safety data sheets and manufacturer's specifications for
the listed components should therefore be studied carefully.
Flammable vapours (e.g. solvent fumes) should be kept away from the arc's
radiation area.
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.
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.

Meandering welding currents
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.
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.

EMC Device Classifications
EMC measures
EMF measures
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.
In certain cases, even though a device complies with the standard limit values
for emissions, 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, additional 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
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
Page 15
15
EN
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).

Factors affecting
welding results
Danger from
shielding gas cylinders
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 deviceside thread of the adapter for the shielding gas connection using suitable Teflon tape.
The following requirements with regard to shielding gas quality must be met if
the welding system is to operate in a correct and safe manner:
- Size of solid matter particles < 40 μm
- Pressure dew point < -20 °C
- Max. oil content < 25 mg/m³
Filters must be used if necessary.
NOTE! There is an increased risk of soiling if ring mains are being
used
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.

Danger from escaping shielding
gas
Safety measures
in normal operation
Risk of suffocation from the uncontrolled escape of shielding gas
Shielding gas is colourless and odourless and, in the event of a leak, can displace the oxygen in the ambient air.
- Ensure an adequate supply of fresh air with a ventilation rate of at least
20 m³/hour.
- Observe safety and maintenance instructions on the shielding gas cylinder or the main gas supply.
- Close the shielding gas cylinder valve or main gas supply if no welding is
taking place.
- Check the shielding gas cylinder or main gas supply for uncontrolled gas
leakage before every start-up.
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.

General
Device concept
The TransSteel (TSt) 2500c, 2700c and
3500c power sources are completely digitised, microprocessor-controlled inverter power sources.
The modular design and potential for system add-ons ensure a high degree of flexibility. The devices are designed for the
welding of steel.
All devices are suitable for:
- MIG/MAG welding
- MMA welding
Functional principle
The central control and regulation unit of the power sources is coupled with a digital signal
processor. The central control and regulation unit and signal processor control the entire
welding process.
During the welding process, the actual data is measured continuously and the device responds immediately to any changes. Control algorithms ensure that the desired target
state is maintained.
The device has a "Power limitation" safety feature. This means that the power source can
be operated at the power limit without compromising process safety.
This results in:
- a precise welding process
- a high degree of reproducibility of all results
- excellent weld properties.
Application areas The devices are used in workshops and industry for manual applications with classical
steel and galvanised sheets.
The TSt 2500c and TSt 2700c power sources are primarily used in light-gauge steel sheet
(light steelwork) applications. Repair, maintenance, and assembly work in shipyards, automotive suppliers, workshops or the furniture construction industry are among the typical
application areas. The TSt 2500c et TSt 2700c power sources thus position themselves in
their power category between the trade/workshop sector and the industry sector.
The TSt 3500c power sources are designed for:
- Machine and equipment construction
- Steelwork
- Plant and container construction
- Metal and gantry construction
- Rail vehicle construction

Options
VRD: safety function
A Voltage Reduction Device (VRD) is an optional safety device for reducing the voltage. It
is recommended for environments in which the risk of an electric shock or electrical accident is increased considerably during arc welding:
- Due to a low human body resistance of the welder
- If the welder is exposed to a clear risk of touching the workpiece or other parts of the
welding circuit
A low human body resistance is possible when there is:
- water in the area
- humidity
- heat, particularly ambient temperatures in excess of 32°C (89.6°F)
In wet, damp or hot locations, humidity or sweat can significantly reduce the skin resistance
and the insulation resistance of protective equipment and clothing.
Such environments can include:
- Temporary dams for draining certain areas of a site during construction work (cofferdams)
- Trenches
- Mines
- Rain
- Areas partly submerged by water
- Spraywater areas
The VRD option reduces the voltage between the electrode and the workpiece. In safe
conditions, the indicator for the currently selected welding process is permanently lit. A
safe condition is defined as follows:
- The output voltage in an open circuit is limited to 35 V.
For as long as the welding operation is active (welding circuit resistance < 200 Ohm), the
indicator of the currently selected welding process flashes and the output voltage may exceed 35 V.
VRD: safety principle
The 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 35 V
- Unintentional contact with the output
voltage does not put the welder at risk
The 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: Welding starts
Page 28
28
In MMA welding mode:
Within 0.3 seconds of end of welding:
- VRD is active again
- The output voltage is limited to 35 V once more

Synergic Central control panel
General The functions on the control panel are all arranged in a logical way. The individual param-
eters required for welding can be
- selected easily using buttons
- altered using buttons or the adjusting dial
- displayed on the digital display during welding
The power source uses the Synergic control panel and certain general items of data such
as sheet thickness, filler metal, wire diameter and shielding gas to calculate the best welding parameters. As a result, stored knowledge is available at all times. All the parameters
can be adjusted manually. The Synergic control panel also allows parameters to be set
manually.

Single-phase operation
Single-phase operation
As an alternative to three-phase operation, the multivoltage variant (MV) of the power
source enables a welding operation with limited power or duration from just a single-phase
supply. The maximum possible welding power is limited due to the dimensioning of the
mains fuse protection, upon which the safety cut-out of the power source is dependant.
If the mains cable has a 20 A or 30 A fuse, the FUS parameter may be changed to 20 A or
30 A. Welding with a higher maximum power or for longer periods is therefore possible.
The FUS parameter is in the level 2 Setup menu and can be set for a single-phase supply
as well as to a US setting (SEt parameter to US).
In order to use the power source in single-phase operation, the following prerequisites
must be fulfilled:
- Correct single-phase power source supply in accordance with the chapter "Installation
and commissioning," section "Connecting the mains cable" - "Fitting the strain-relief
device, single-phase operation."
The following table shows which mains voltages and fuse values limit the welding current
in single-phase operation:
The welding current data applies at an ambient temperature of 40°C (104°F).
At a mains voltage of 240 V and a fuse value of 30 A the maximum value of 220 A for the
MIG/MAG welding for instance is possible at a duty cycle of 40 %.

* The 100% values relate to welding with no time limits and without cooling breaks
Page 52

In single-phase operation a safety cut-out function prevents a triggering of the fuse at higher welding power values. The safety cut-out function is active at fuse values of 15 A, 16 A
and 20 A and determines the possible welding time, without triggering of the fuse. If a cutout of the welding current results due to exceeding the pre-calculated welding time, the service code „toF“ is displayed. In addition to the readout „toF“ from now on a countdown runs
for displaying the remaining waiting time, until the welding readiness is restored. Then the
message disappears an the power source is operational again.
At a fuse value of 30 A the temperature monitoring of the power source ensures the timely
shutdown of the welding current, yet before the fuse triggers. This results in the display of
the service codes „to1“ to „to7“. Detailed information concerning the servicecodes „to1“ to
„to7“ is located in chapter „Troubleshooting and maintenance, section „Displayed service
codes“. If there is no defect or soiling of the cooling components, here the power source is
also ready for welding again after an adequate welding break.
Explanation of
the term „duty cycle“ in singlephase operation
For single-phase operation duty cycle values are given in the chapter „Technical data“, depending on the existing fuse value and the welding current. The percentage rates of this
duty cycle values indeed relate as well to the 10-minute cycle, as explained in chapter
„Technical data“ for the general duty cycle, however the cooling phase of the fuse is rated
at only approximately 60 s. Thereafter, the power source is already operational again.
For reasons of technical standards the duty cycle in single-phase operation is only given
for the time until the cut-out within the first welding cycle takes place. If the reference to the
10 minute cycle would also persist with regard to the cooling phase, which is usually valid
for specifying the duty cycle, in practice longer welding phases than specified would be
possible. You see that the specification relates to cooling phases of only approximately 60
s, after which the power source is already operational again.
The example given in the following shows the standard compliant welding and break cycles, at a welding current of 180 A and a duty cycle of 15 %.
Welding time in
single-phase operation
The following diagram shows the welding time, which is possible according to the technical
standards, depending on the given fuse value and the welding current.

EN
If you release the "Wire threading" button and press it again before one second has
elapsed, the sequence starts again from the beginning. This makes it possible to continuously position the wire at a low wire feed speed of 1 m/min or 39.37 ipm where necessary.
If there is no "Wire threading" / "Gas-test" button, the torch trigger can be used in the usual way. Before using the torch trigger for wire threading, proceed as follows:
Press the "Mode" button to select 2-step mode
Set the "Ito" parameter to "Off" in the Setup menu
IMPORTANT! If the torch trigger is pressed instead of the "Wire threading"/"Gas-test"
button, the welding wire runs at the feeder creep speed (depending on the welding program) for the first 3 seconds. After these 3 seconds, wirefeeding is briefly interrupted.
The welding system detects that the welding process should not start, but that the wire is
to be fed in. At the same time, the gas solenoid valve closes, and the welding voltage on
the wire electrode is switched off.
If the torch trigger is kept pressed, wire feeding restarts immediately without shielding gas
and welding voltage, and the process continues as described above.
- Hold the button for up to one second
... the wire feed speed stays at 1 m/
min or 39.37 ipm for the first second.
- Hold the button for up to 2.5 seconds
... after one second, the wire feed
speed increases over the next 1.5
seconds.
- Hold the button for more than 2.5
seconds ... after 2.5 seconds, the
wire is fed at a constant rate equal to
the wire feed speed set for the Fdi
welding parameter.
CAUTION! Risk of injury and damage from electric shock and from the wire electrode emerging from the torch. When pressing the torch trigger
- keep the welding torch away from your face and body
- wear suitable protective goggles
- do not point the welding torch at people
- make sure that the wire electrode does not touch any conductive or earthed
parts (e.g. Housing etc.)

Power limitation
Safety function "Power limitation" is a safety function for MIG/MAG welding. This means that the power
source can be operated at the power limit whilst maintaining process safety.
Wire feed speed is a determining parameter for welding power. If it is too high, the arc gets
smaller and smaller and may be extinguished. In order to prevent this, the welding power
is lowered.
For the selected "MIG/MAG standard synergic welding" process, the symbol for the
"Wire feed speed" parameter flashes as soon as the safety function trips. The flashing continues until the next welding start-up, or until the next parameter change.
If the "Wire feed speed" parameter is selected, the reduced value for wire feed
speed is displayed.

Advantages
- Improved ignition, 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

Function
During the specified hot-current time (Hti),
the welding current is increased to a certain
value. This value (HCU) is higher than the
selected welding current (IH).
Anti-stick function
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 by activating the anti-stick function. 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.
The anti-stick (Ast) function can be activated and deactivated in the Setup parameters in
"Setup menu: level 2".

Unit: Setting range: Aut, On, OFF
Factory setting: Aut
Aut: The cooling unit cuts out after a 2-minute welding off-time.
IMPORTANT! If the coolant temperature and flow monitoring options have been
installed in the cooling unit, the cooling unit cuts out as soon as the return-flow
temperature drops below 50 °C, but at the earliest after a 2-minute welding offtime.
On: The cooling unit is always ON
OFF: The cooling unit is always OFF
IMPORTANT! If the FAC welding parameter is used, the C-C parameter is not
reset to the factory setting. If the MMA welding process is selected, the cooling
unit is always switched off, even if the switch is in the "On" position.
C-t Cooling Time
(only with connected cooling unit)
Time from when flow monitoring is triggered until the "no | H2O" service code is
output. For example, if there are air bubbles in the cooling system, the cooling
unit will not cut out until the end of this preset time.

10000 to 99999 / 10.0 to 99.9
(without "ones" and "tens" digits, e.g. 23580 kJ -> 23.6)
ALC Arc Length Correction - correction of the arc length via the welding voltage
Setting range: ON / OFF
Factory setting: OFF
The arc length depends on the welding voltage. The welding voltage can be adjusted to suit individual needs in Synergic operation.
If the ALC parameter is set to "OFF", the welding voltage cannot be adjusted.
The welding voltage is automatically determined by the selected welding current
or wire speed. If the arc length correction is adjusted, the voltage changes, but
the welding current and wire speed remain the same. When setting the arc length
correction using the adjusting dial, the left display is used for the correction value
of the arc length. The welding voltage value on the right display changes simultaneously. Afterwards the left display shows the original value, e.g. welding current.

Measuring welding circuit resistance r
General Measuring the welding circuit resistance r makes it possible to have a constant welding re-
sult at all times, even with hosepacks of different lengths. The welding voltage at the arc is
then always precisely regulated, regardless of the length and cross-sectional area of the
hosepack. The use of arc length correction is no longer required.
The calculated welding circuit resistance is shown on the display.
r = welding circuit resistance in milliohm (mOhm)
If the welding circuit resistance r has been measured correctly, the set welding voltage will
correspond exactly to the welding voltage at the arc. If you manually measure the voltage
on the output jacks of the power source, this voltage will be higher than the welding voltage
at the arc - that is, higher by the same amount as the voltage drop of the hosepack.
Measure the
welding circuit resistance r
Establish a grounding (earthing) connection to the workpiece
Accessing the Level 2 (2nd) Setup menu
Select parameter "r"
Remove the gas nozzle from the welding torch
Screw on the contact tip
Place the contact tip flush against the workpiece surface
Press the torch trigger briefly
- The welding circuit resistance is calculated. "run" is shown on the display during
the measurement.
The measurement is finished when the welding circuit resistance is shown on the display
in mOhm (e.g. 11.4).
Fit the gas nozzle back onto the welding torch
NOTE! The welding circuit resistance r depends on the hosepack used:
- If the length or cross-sectional area of the hosepack has changed, measure
the welding circuit resistance r again
- Measure the welding circuit resistance for every welding process separately
with the appropriate welding power-leads
NOTE! In order to obtain good welding results, it is essential to measure the welding circuit resistance correctly. Make sure that the contact between the earthing
clamp and the workpiece is on a cleaned workpiece surface.
NOTE! Make sure that the contact between the contact tip and the workpiece is
on a cleaned workpiece surface.

Displaying welding circuit inductivity L
General Laying of the hosepacks has a significant effect on welding circuit inductivity and therefore
affects the welding process. It is important to lay the hosepacks correctly in order to obtain
the best possible welding result.
Displaying welding circuit inductivity L
The setup parameter "L" is used to display the most recently calculated welding circuit inductivity. The welding circuit inductivity is calibrated at the same time as the welding circuit
resistance r is calculated. Detailed information can be found in the "Measuring welding circuit resistance r" section.
Access the setup menu level 2 (2nd)
Select parameter “L”
The most recently calculated welding circuit inductivity L is shown on the right-hand digital
