3 Intended use
3.1 General
A MIG/MAG welding torch ready for operation consists of: hose package, handle and torch neck,
including all necessary accessories and wearing parts.
All elements together form a functional unit which, supplied with the relevant operating materials,
generates an arc for welding. For welding, a wire electrode is fed through the hose package and the
welding torch. The arc and molten pool are shielded using inert gas (MIG) or active gas (MAG).
The wire electrode is a melting solid or cored wire which is fed through the contact tip. The contact tip
transfers the welding current to the wire electrode. The arc is formed between the wire electrode and
workpiece.
Hazards due to improper usage!
Hazards may arise for persons, animals and material objects if the equipment is not
used correctly. No liability is accepted for any damages arising from improper usage!
• The equipment must only be used in line with proper usage and by trained or expert staff!
• Do not modify or convert the equipment improperly!
3.2

Applications

3.2.1

MIG/MAG standard welding

Metal arc welding using a wire electrode whereby gas from an external source surrounds the arc and the
molten pool to protect them from the atmosphere.
3.2.2

MIG/MAG pulse welding

Welding process for optimum welding results when joining stainless steel and aluminium thanks to
controlled drop transfer and targeted, adapted heat input.
3.2.3

MIG/MAG cored wire welding

Welding with cored wire electrodes consisting of a metal casing and a powder core.
As with MIG/MAG standard welding, the arc is protected from the atmosphere by shielding gas. The gas
is supplied either externally (gas shielded cored wires) or produced in the arc by means of the powder
core (self-shielding cored wires).
