Movable TIG welding inverter machines

Convincing capacity with direct and alternating current: The TIG welding machine for perfect automated welding results.

The TIG welding machines type GL/GLW 270/350/500 combine modern micro processor controlled inverter technology with traditional robustness and high operating convenience. An infinite adaptation of the start current to the electrode diameter and a constant stable and soft arc in all areas offer the prerequisite for optimum automatic welding results. Depending on the application, the welding machine is availabe as DC or AC/DC machine.
