For welding surfaces that will be visible, a handheld TIG torch creates a neater, more aesthetic weld than MIG welding or spot welding. No consumable metal wire is used with a TIG torch. Instead, the arc from a charged tungsten rod melts a filler rod along with the workpiece surface to form the weld. Also unlike MIG welding, TIG torches generate little to no sparking, spatter, smoke, or fume generation. A feature shared by both TIG welding and MIG welding is the shielding gas (usually argon) dispensed by the torch, keeping contaminants from the weld. TIG torches may vary by length of cable and output range (in amps), among other considerations. Note: TIG welding is sometimes called gas tungsten arc welding (GTAW) or heli-arc welding. Lastly, all welding torches, including a TIG torch, require certain accessories, so be sure to check out our welding tips, and welding nozzles.
