0154623008 - ESAB M12 Heavy Duty Contact Tip 1.6mm (1/16") - 5 Pack

Keep Your Arc Smooth and Steady

When you are burning 1/16" wire, you are likely pushing some serious amps, and you need a contact tip that can take the heat. The ESAB M12 Contact Tip is built exactly for that purpose. Unlike smaller tips that overheat and fuse up when you are in the middle of a long pass, these heavy-duty M12 tips have the mass and the threading to stay cool and keep the current flowing smoothly. The M12 thread isn't just about size; it locks in tight to your gun, ensuring you don't lose voltage at the connection point, which means a crisper, more consistent arc at the puddle.

We know that nothing kills production speed like a contact tip that constantly burns back or keyholes. These ESAB tips are machined with a smooth bore that lets your 1.6mm wire glide through without snagging, reducing the drag on your drive rolls and liner. Whether you are welding structural beams, heavy machinery, or thick plate, having a reliable contact point is the first step to a defect-free weld. The copper alloy is tough enough to resist the wear of the wire sliding through but conductive enough to give you that instant arc start every time you pull the trigger.

This pack comes with five tips, so you can keep a few in your pocket or your toolbox and never be caught short in the middle of a shift. Swapping them out is quick, and the precision threads mean you won't be fighting to get them seated correctly. If you are running a heavy-duty setup that calls for M12 tips, stick with genuine ESAB parts to get the performance your machine was designed to deliver. Stop fighting your equipment and start welding with confidence.
