GRAND TIG 250 DC PULSE three phase inverter power source for TIG DC and TIG PULSE DC with the possibilty of MMA (stick) usage.
In TIG DC all the main parameters are adjustable in order to obtain the best welding. With a very good high frequency igniction, GRAND TIG 250 DC PULSE can easy weld stainless steel, copper alloys, mild steel and titanium. PULSE TIG permits high performance on ultra thin surfaces with reduced deformations. In MMA Mode Hot Start and Arc Force are adjustable in order to permit to the operator to work easily and with excellent results. Antisticking helps the welder stopping the welding current when the electrode is glued to the workpiece. It is equipped with temperature, voltage and current sensors for high protection and it is designed to avoid failures due to voltage spikes as when using diesel generator. Hardy and with its high duty cycle (250 A at 60%) this power source is ideal for food industry, petrochemical plants and for industrial steel fabrication where a very high welding performance is required.
