Recommended Welding Method
ER1100 aluminium welding wire is suitable for both MIG and TIG welding. AC TIG welding with pure argon shielding gas is recommended for optimal results. Before starting, ensure the part to be welded is clean and free of oil or dust. Avoid any moisture on the workpiece, the welding wire, or in the environment, as it can affect weld quality.
