Risk of injury due to unexpected start-up
For the entire duration of maintenance, servicing,
unmounting, and repair work, the following instructions
must be adhered to:
• Switch o the power supply.
• Cut o the compressed air supply.
• Pull the power plug.
All elements together form an operating unit that
provides a plasma arc for welding when supplied with
the appropriate operation resources. The welding wire
required for welding is fed through the welding gun
system A7 MIG Gun 500-w all the way to the contact tip.
The contact tip transmits the welding current to the
welding wire, producing an arc between the welding
wire and work piece. The light arc and the molten pool
are protected by the inert gas (MIG) or active gas (MAG).
