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.
Otherwise, a protective mask with an air supply must be worn.
10
Danger from flying sparks
Risks from mains
current and welding current
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 system is powerful enough,
then 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.
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 wire-feed unit 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. Loose connections, scorched, damaged or inadequately dimensioned cables and leads must be repaired/replaced immediately.
Do not sling cables or leads around the body or parts of the body.
11
EN
Meandering welding currents
The electrode (rod electrode, tungsten electrode, welding wire, etc) must
- never be immersed in liquid for cooling
- never be touched 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.
If the device is operated on a mains supply without a ground conductor and
using a socket without a ground conductor contact, this 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
13
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).
14
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.

General
Device concept
The TransSteel (TSt) 2500c 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 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 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
24
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

System components
General The power sources can be operated with various system components and options. This
makes it possible to optimise procedures and to simplify machine handling and operation,
as necessitated by the particular field of application in which the power source is to be
used.
