0154623003 - ESAB M12 Heavy Duty Contact Tip 4.0mm (5/32") - 5 Pack

Reliable Performance for Heavy Fabrication

When you are welding with 5/32" (4.0mm) wire, you are likely moving a lot of metal and running at high amperages. In these demanding conditions, your contact tip takes a beating. The ESAB M12 Contact Tip (0154623003) is built to withstand the heat and stress of heavy fabrication. Unlike smaller tips that overheat and fuse quickly, this robust M12 tip offers the mass and durability needed for serious structural work, shipbuilding, or pipe welding applications.

A worn contact tip is the number one cause of erratic arcs and wire feed issues. If the bore becomes oval-shaped or clogged with spatter, you lose that vital electrical connection, leading to micro-arcing inside the tip and frustrating burn-backs. This 5-pack ensures you always have a fresh replacement on hand, so you don't have to stop production to hunt for parts. The precision bore ensures your 4.0mm wire glides through smoothly while maintaining constant electrical contact for a buttery-smooth arc.

Designed for professional welders who demand consistency, these genuine ESAB tips fit securely into compatible heavy-duty diffusers or torch heads. The M12 threading ensures a tight fit that won't rattle loose during operation. Whether you are running a sub-arc tractor or a heavy-duty handheld gun, trusting genuine ESAB consumables means less troubleshooting and more arc-on time. Upgrade your consumables inventory with this pack and keep your heavy welding operations running at peak efficiency.
