Inverter
These operating instructions must be read before commissioning.
Failure to do so may be dangerous.
Machine may only be operated by personnel familiar with the appropriate safety
regulations.
The machines bear the conformity mark and thus comply with the
• EC Low Voltage Directive (73/23/EEC)
• EC EMC Directive (89/336/EEC)
Geräte können entsprechend IEC 60974, EN 60974, VDE 0544 in Umgebung mit erhöhter
elektrischer Gefährdung eingesetzt werden.

Page 4: Safety Instructions
Safety instructions For Your Safety: Ignoring the following safety precautions can be fatal. Observe accident prevention regulations. Designed use This machine is manufactured according to the current state of the art and current regulations and standards. It is to be operated only for the designed use (see Chap. Commissioning/Area of application). - Page 5 Safety instructions Smoke and gases can lead to breathing difficulties and poisoning. · Do not breathe in smoke and gases. · Ensure that there is sufficient fresh air. · Keep solvent vapours away from the arc radiation area. Chlorinated hydrocarbon fumes can be converted into poisonous phosgene by ultraviolet radiation.
- Page 6 Safety instructions Interference by electrical and electromagnetic fields is possible e.g. from the welding machine or from the high-voltage pulses of the ignition unit. · As laid down in Electromagnetic Compatibility Standard EN 50199, the machines are intended for use in industrial areas; if they are operated e.g. in residential environments problems can occur in ensuring electromagnetic compatibility.

The hotstart device makes it possible to ignite and re-ignite critical stick electrodes easily. Adjustable arcforcing Shortly before the electrode threatens to stick, the arcforcing device sets an increased current designed to prevent the electrode from sticking. -
Page 11: Function Sequence For Mma Welding
Function specification Antistick If the stick electrode sticks despite the arcforcing device, the machine automatically switches over to the minimum current within about 1 second to prevent the electrode overheating. If the antistick device has been triggered, check the welding current setting and correct if necessary. Functional sequence for MMA welding Hotstart-Strom Hauptstrom... -

Page 15: Commissioning
Commissioning Commissioning Area of application The machines are used exclusively for stick electrode direct current welding. 5.1.1 Proper usage These welding machines are suitable only for MMA direct current welding for rutile, basic and cellulose electrodes. Any other use is regarded as "improper" and no liability is assumed for any damage arising therefrom. -
Page 16: Maintenance And Care
Maintenance and care Under normal operating conditions, these welding machines are largely maintenance-free and require a minimum of care. However, a number of points should be observed to guarantee the fault-free operation of your welding machine. These include regular cleaning and checking, as described below, depending on the level of contamination in the environment and the amount of usage of the welding machine. -
