Intended useApplications3 Intended useThis machine has been manufactured according to the latest developments in technology and currentregulations and standards. It must only be operated in line with the instructions on correct usage.WARNINGHazards due to improper usage!Hazards may arise for persons, animals and material objects if the equipment is notused 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!3.1 Applications3.1.1 MIG/MAG standard weldingMetal arc welding using a wire electrode whereby gas from an external source surrounds the arc and themolten pool to protect them from the atmosphere.3.1.2 rootArcStable, soft, short arc even with long welding leads; ideal for simple, reliable root welding without poolsupport, easy gap bridging.3.1.3 forceArcWelding with a powerful forced arc, deep fusion penetration and virtually spatter-free weld seams of thehighest quality.3.1.4 MIG/MAG pulse weldingWelding process for optimum welding results when joining stainless steel and aluminium thanks tocontrolled drop transfer and targeted, adapted heat input.3.1.5 TIG (Liftarc) weldingTIG welding process with arc ignition by means of workpiece contact.3.1.6 MMA weldingManual arc welding or, for short, MMA welding. It is characterised by the fact that the arc burns betweena melting electrode and the molten pool. There is no external protection; any protection against theatmosphere comes from the electrode.3.1.7 Air arc gougingDuring air arc gouging, bad welding seams are heated with a carbon electrode and then removed withcompressed air. Special electrode holders and carbon electrodes are required for air arc gouging.16099-005234-EW50116.04.2012
