0559211707 - ESAB 4.0mm Contact Tip for A2/A6 800A Heads

Reliable Performance for High-Amp Welding

When you are running heavy automatic welding equipment, the last thing you need is a contact tip failure in the middle of a long seam. The ESAB 0559211707 Contact Tip is built for the professional welder and operator managing ESAB A2 or A6 welding heads. Rated for a massive 800 amps, this tip is the workhorse you need for running 4.0mm wire in Submerged Arc (SAW) or heavy MIG applications. It is designed to handle the heat and keep the current flowing smoothly, ensuring your arc stays stable and your welds pass inspection every time.

We know that in heavy fabrication, "time is money" isn't just a saying—it's the reality of the shop floor. Constant tip changes due to burn-back or keyholing slow down production and frustrate operators. This ESAB tip features a durable copper alloy construction that resists wear and deformation better than standard tips. The M12 threads screw in cleanly and stay tight, providing a solid electrical connection that doesn't fluctuate. The 4.0mm bore is machined perfectly to guide the wire without excessive drag or slop, giving you the control you need over bead placement and penetration.

Whether you are welding thick structural plates, pressure vessels, or large diameter pipe, trusting your consumables is key to a stress-free shift. This genuine ESAB part guarantees compatibility with your 800A torch setup, eliminating the guesswork of fitting aftermarket parts. Keep your automatic welding heads running like new and maintain high deposition rates with a contact tip that is as tough as the job you are doing.
