0559210028 - ESAB 300A MIG Contact Tip for Mild Steel Wire

High-Performance ESAB 300A MIG Contact Tip

The ESAB 0559210028 is a premium 300 Amp contact tip designed specifically for mild steel MIG welding applications. As a critical component in the welding circuit, the contact tip is responsible for transferring welding current to the wire as it passes through the gun. This specific model is manufactured to ESAB's exacting standards, ensuring superior conductivity and resistance to heat buildup, which are essential for maintaining a consistent 300A output during extended welding cycles.

Constructed from high-grade copper alloy, this tip offers excellent wear resistance against the abrasion caused by moving wire. The bore is drilled to precise specifications to prevent micro-arcing inside the tip, a common cause of burn-back and wire fusion. It is specifically categorized for mild steel applications, meaning the clearance is optimized for the expansion rates and surface characteristics of mild steel solid wires. This attention to detail results in a smoother arc, less spatter, and reduced downtime for tip changes.

Welders Supply provides this genuine ESAB replacement part to ensure your equipment performs at peak efficiency. Compatible with specific ESAB MIG guns rated for this amperage class, this tip is an essential consumable for any welder working with mild steel. Keep your tool crib stocked with the 0559210028 to ensure you are always ready for heavy-duty fabrication tasks.
