TIG welding is an arc welding process where argon gas is utilized to protect the welded metal. To be more specific, an inert shielding gas will continuously be expelled from the nozzle of the welding torch during the welding process, forming a protective atmosphere around the arc to protect the weld area and the electrode from oxidation or other atmospheric contamination. Our TIG welding machine can be applied for the welding of stainless steel and ferrous metals and superior quality weld seams can be ensured. A filler metal may or may not be used depending on the specific requirements of the workpiece.
