851075 WELDER TIG AC/DC DUAL CURRENT, 300A 1 PHASE 200V 300P W/PULSE

Tig (Tungsten Inert Gas) welding is an arc welding process that uses a non-consumable tungsten electrode to produce the arc, and used for critical weld joints, welding metals, such as aluminium, stainless steel, copper, brass, titanium, nickel, even two dissimilar metals, other than common steel, and where precise, small welds are needed. Tig welding requires a shielding gas to protect the weld area from the air (typically pure Argon gas), and utilizes a constant current welding power supply to generate an electric arc between the tungsten electrode and the workpiece, using the resultant heat to create the weld. The pulse function is used for giving a more stable arc than not pulsing. This allows for welding thinner metals and high heat conductive metals without burning through.
