Recommended Welding Method

ER 5087 aluminium welding wire is suitable for both MIG and TIG welding using alternating current and pure argon as shielding gas. To ensure clean, high-quality welds, it’s important to remove any oil, dust, or moisture from the area to be weld and from the welding wire surface before starting.
