Recommended Welding Method

Suitable for both MIG and TIG welding processes. AC TIG welding with pure argon shielding gas is recommended to ensure arc stability and weld quality. Before starting, clean the part to be welded thoroughly to remove any oil, dust, or surface oxidation. Moisture on the base metal or filler wire should be avoided to prevent weld defects.
