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 off the power supply.
• Cut off 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-g 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).

10.1 The neck

Standard A7 MIG Gun 500-g necks are available in the
following geometries: straight, 22°, 35°, and 45° bends.
Special designs will be manufactured upon request,
depending on the application.

The uniform interface at the connecting module makes all
torch necks compatible with one another.
