Based on latest evolution IGBT inverter technology, MATRIX 3001 HF, TIG power source with high frequency arc striking, is equipped with a simple digital display to easily adjust basic welding functions only as clearly shown by its user friendly display. Its excellent technical characteristics, coupled with its innovative digital control, allow high quality TIG welding, suitable for the toughest industrial applications. This robust power source, with DC output only, enables TIG welding of mild and stainless steel, copper and its alloys. MATRIX 3001 HF also offers excellent performances in MMA welding with the most difficult basic, rutile and stainless steel electrodes, presettable on the keyboard. Its overall features make it greatly recommended in pipe welding applications requiring first TIG root pass with HF followed by MMA final filling up of the welded joints.
