A workplace-specific emission value for welding (and cutting) cannot be specified because this value depends on the welding process and the environmental conditions. It is influenced by a wide range of parameters, such as the welding process itself (MIG/MAG, TIG welding), the selected current type (direct current, alternating current), the power range, the type of weld metal, the resonance properties of the workpiece, the workplace environment, and many other factors.

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.

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.

• 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.

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

• 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.

The power source is intended exclusively for MIG/MAG, rod electrode, and TIG welding.
Utilization for any other purpose, or in any other manner, shall be deemed to be not in accordance with the intended purpose.
The manufacturer shall not be held liable for any damages arising from such use.

• Following all the instructions in these Operating Instructions
• Carrying out all the specified inspection and maintenance work

• Protection against penetration by solid foreign bodies with diameters > 12 mm (0.49 in.)
• Protection against spraywater at any angle up to 60° from the vertical

The device can be set up and operated outdoors in accordance with protection class IP 23.
Direct moisture (e.g., from rain) must be avoided.

The ventilation channel is a very important safety device. When choosing the device location, ensure that the cooling air can enter and exit unhindered through the ventilation openings on the front and back of the device. Electroconductive metallic dust (e.g., from grinding work) must not be allowed to get sucked into the device.

The devices are designed for the grid voltage stated on the rating plate. If the mains cable or mains plug has not been attached to your version of the appliance, these must be installed according to national standards. Fuse protection for the grid lead can be found in the technical data.

The power source is generator-compatible.

The maximum apparent power S_1max of the power source must be known in order to select the correct generator output.
The maximum apparent power S_1max of the power source is calculated as follows:
S_1max = I_1max x U₁

I_1max and U₁ according to the device rating plate or technical data.

The generator apparent power S_GEN needed is calculated using the following rule of thumb:
S_GEN = S_1max x 1.35

A smaller generator may be used when not welding at full power.

When single phase devices are being operated with a three-phase generator, note that the stated apparent power of the generator is often just the total that can be present across all three phases of the generator. If necessary, obtain further information about the single-phase power of the generator from the generator manufacturer.

The mains fuse protection selected on the power source limits the power drawn in from the grid and in turn the possible welding current. This prevents the automatic circuit breaker (e.g., in the fuse box) from tripping straight away.

The desired mains fuse protection can be selected on the power source depending on the grid voltage and automatic circuit breaker used.

The following table shows which grid voltages and fuse ratings limit the welding current.

TSt 2200:

TSt 2200 MV:

• The country-specific setting has been set to "US"
• The grid lead has a 20 A fuse
• The power source is supplied with a grid voltage of 120 V

The welding current data applies at an ambient temperature of 40 °C (104 °F).

A safety cut-out prevents the automatic circuit breaker from tripping at higher welding powers. The safety cut-out defines the possible welding duration without the automatic circuit breaker tripping. If the precalculated weld time is exceeded, thus causing the welding current to switch off, the service code "toF" is displayed. A countdown immediately appears next to the "toF" indicator, which shows the remaining time until the power source is ready for welding again. After this time, the message disappears, and the power source is ready for operation again.

Depending on the selected fuse, the safety cut-out limits the maximum currents of the selected process. As a result, it is possible that welding can no longer occur at the saved operating points if these were saved before selecting the fuse.

If welding is nevertheless carried out at one of these operating points, the power source operates at the limit value of the selected fuse – the power limitation is active. The operating point should be re-saved in accordance with the power limitation.

The mains fuse protection selected on the power source limits the power drawn in from the grid and in turn the possible welding current. This prevents the automatic circuit breaker (e.g., in the fuse box) from tripping straight away.

A countdown immediately appears next to the "toF" indicator, which shows the remaining time until the power source is ready for welding again. After this time, the message disappears, and the power source is ready for operation again.

Depending on the selected fuse, the safety cut-out limits the maximum currents of the selected process. As a result, it is possible that welding can no longer occur at the saved operating points if these were saved before selecting the fuse.

If welding is nevertheless carried out at one of these operating points, the power source operates at the limit value of the selected fuse – the power limitation is active. The operating point should be re-saved in accordance with the power limitation.

In order to achieve optimum wire electrode feed, the feed rollers must be suitable for the diameter and alloy of the wire being welded.

The spot and stitch welding modes are MIG/MAG welding processes.

Spot welding is used on welded joints on overlapping sheets that are only accessible on one side.

Stitch welding is used for light-gage sheets.
As the wire electrode is not fed continuously, the weld pool can cool down during the intervals. Local overheating leading to the parent material being melted through is largely avoided.

Pulsed welding is welding with a pulsing welding current. It is used to weld steel pipes out-of-position or to weld thin sheet metal.

• If the amperage is too low, the parent material will not be melted enough
• If overheating occurs, there is a danger that the liquid weld pool may drip.

Pulsed welding is welding with a pulsing welding current. It is used to weld steel pipes out-of-position or to weld thin sheet metal.

• If the amperage is too low, the parent material will not be melted enough
• If overheating occurs, there is a danger that the liquid weld pool may drip.

• A low base current I-G rises steeply to the significantly higher pulse current I-P and drops back to the base current I-G after the Duty cycle dcY time.
• This results in an average current that is lower than the set pulse current I-P.
• During pulse welding, small sections of the welding location melt quickly and then rapidly re-solidify.

The power source controls the "Duty cycle dcY" and "Base current I-G" parameters according to the set pulse current (welding current) and pulse frequency.

Hti	Hot-current time, 0 - 2 s, factory setting 0.5 s
HCU	HotStart current, 100 - 200%, factory setting 150%
IH	Main current = set welding current

The Hti and HCU parameters can be set in the Setup menu. For a parameter description see section Parameters for MMA Welding from page (→).

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 (I_H).

This function is activated at the factory.

As the arc becomes shorter, the welding voltage may also fall so that the rod electrode is more likely to stick to the workpiece. This may also cause the rod electrode to burn out.

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. The welding process can be resumed without problems once the rod electrode has been detached from the workpiece.

For a parameter description see section Parameters for MMA Welding from page (→).

Measuring the welding circuit resistance makes it possible to have a constant welding result 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 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.

• If the length or cross-sectional area of the hosepack has changed, measure the welding circuit resistance again
• Measure the welding circuit resistance for every welding process separately with the appropriate welding power-leads
