Recommended Welding Method

When preparing for MIG or TIG welding, it's important to use alternating current (AC) and pure argon shielding gas to maintain arc stability and protect the weld pool. Always clean the area to be weld beforehand to remove any oil, moisture, or surface oxidation, this helps reduce porosity and ensures consistent weld quality under demanding conditions.
