Tungsten Inert Gas (TIG) welding, also known as Gas Tungsten Arc Welding (GTAW), is an arc welding process that produces the weld via a non consumable tungsten electrode. TIG welding must be carried out using a constant current power source (either DC or AC), which is essential for avoiding excessively high currents being drawn when the electrode is short circuited onto the workpiece surface. This could happen either deliberately during arc starting or inadvertently during welding. TIG welders are ideal for joining metals like stainless steel, aluminium, nickel & copper alloys, cobalt and titanium. These welders are used for producing spatter free weld seams.
Raptor Supplies offer a broad range of TIG welders from brands like American Weldquip, Hobart, Lincoln Electric, Miller Electric & Tweco. Miller Electric TIG welders come with a power source, an external water cooler with coolant, running gear, a water-cooled TIG torch, a TIG consumables kit, a working cable with a clamp, a flow gauge / regulator, a gas hose, and either a wired or wireless foot control. The lightweight design of these TIG welders offers portability for moving from one workstation to another. They also have digital meters for displaying actual voltage & current ratings and adaptive hot start for providing arc strikes without sticking. Lincoln Electric TIG welders are equipped with an AC Auto Balance feature that allows the unit to automatically adjust for the optimal mix of cleaning and penetration. The operator simply has to select polarity, process and desired amperage to begin welding. Choose from a wide range of TIG welders, available in one & three phase variants on Raptor Supplies.
