Lift Arc Tig Welders

Lift arc tig welders feature two variants. Variant 1 is a Touch Lift Arc start that can sense the short circuit that results when touching the tungsten to the work piece when arc striking reducing the current momentarily until the tungsten lifts away forming igniting the TIG arc with minimal tungsten contamination. Variant 2 is a Scratch Lift Arc start whereby the tungsten is struck like a match on the workpiece at a set start current after which the main control panel welding current is sloped in to the preset value.
