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 speed is a determining parameter for welding power. If it is too high, the arc gets smaller and smaller and may be extinguished.
MIG/MAG Operating Modes General WARNING! Operating the device incorrectly can cause serious injury and damage to prop- erty. ▶ Do not use the functions described here until you have fully read and under- stood the Operating Instructions. ▶ Do not use the functions described here until you have fully read and under- stood all of the Operating Instructions of the system components, especially the safety rules.

Danger of injury and damage from electric shock and from the wire electrode emerging from the torch.
MIG/MAG Standard Manual Welding General The MIG/MAG standard manual welding process is a MIG/MAG welding process with no synergic function. Changing one parameter does not result in any automatic adjustments to the other parameters. All of the variable parameters must therefore be adjusted indi- vidually, as dictated by the welding process in question.
Use the "Parameter selection" buttons to select the welding parameter (wire speed) Use the appropriate selection dial to set the wire speed Use the "Parameter selection" buttons to select the welding parameter (welding voltage) Use the appropriate selection dial to set the welding voltage The welding parameter values are shown in the digital display located above All welding parameter set values remain stored until the next time they are changed.
Spot welding and stitch welding General The spot and stitch welding modes are MIG/MAG welding processes. Spot welding is used on welded joints on overlapping sheets that are only access- ible 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.
Stitch Welding Press the "Material" button to select the filler metal to be used. Press the "Wire diameter" button to select the diameter of the wire electrode used. Press the "Shielding gas" button to select the shielding gas to be used. The assignment of the SP position is in the welding program tables in the ap- pendix.

TIG Welding TIG Welding Press the "Process" button to select the TIG welding process: Press the "Parameter selection" button to select the amperage parameter. Use the selection dial to set the desired amperage. The amperage value is shown on the left-hand digital display. All the parameter set values are saved until the next time they are changed.
Pulse welding Applications 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. In these applications, the welding current set at the start of welding is not always optimum for the entire welding process: 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.
