1. GENERAL SAFETY CONSIDERATIONS FOR ARC WELDING
EXTRA PRECAUTIONS
The operator should be properly trained to use the welding
machine safely and should be informed about the risks related to

Technical protection measures MUST BE taken as described
in 5.10; A.7; A.9. of the “IEC TECHNICAL SPECIFICATION or

- Make sure that the power supply plug is correctly connected
to the earth protection outlet.
- Do not use the welding machine in damp or wet places and do
not weld in the rain.
RESIDUAL RISKS
- Do not use cables with worn insulation or loose connections.
- OVERTURNING: position the welding machine on a horizontal
surface that is able to support the weight: otherwise (e.g.
inclined or uneven floors etc.) there is danger of overturning.
- IMPROPER USE: it is hazardous to use the welding machine

INTRODUCTION
These single phase welding machines are power sources based on
state-of-the-art IGBT inverter technology with completely digital
control, and are equipped with an integrated wire feeder.
The welding machines can be used for high quality welding in
continuous synergic MIG/MAG, TIG and MMA and in pulsed synergic
MIG/MAG when included.
The wire feeder is equipped with a 2-roller motorised wire puller unit
