Recommended Welding Method

This type of welding wire can be used with both MIG and TIG welding techniques. AC TIG welding with pure argon shielding gas is preferred for optimal arc stability. To ensure clean results, it's important to thoroughly clean the welding area before welding and keep both the workpiece and welding wire free from moisture or contaminants.
