5 Functional description
The functioning welding torch system MIG/MAG comprises the following components:
• Torch neck with equipment parts and parts subject to wear, Handle tube, Hose assembly
including central plug
All elements together form an operating unit which provides an arc for welding when supplied
with the appropriate operating resources. The welding wire required for welding is fed by the
welding torch system 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) and the active gas (MAG).
