0157312880 - ESAB A6 Contact Jaw Replacement

Keep Your Sub-Arc Running Smoothly

If you are running an ESAB A6 or A2 tractor or beam welder, you know that the contact jaw is where the rubber meets the road—or rather, where the power meets the wire. The ESAB 0157312880 Contact Jaw is the direct replacement part you need when your current jaws start to wear out. In heavy-duty Submerged Arc Welding (SAW), a worn contact jaw can cause all sorts of headaches, from wandering arcs to sputtering starts and uneven heat input. Swapping in a fresh jaw is one of the easiest ways to bring your weld quality back up to spec.

These jaws are built tough to handle the heat and friction of continuous automated welding. Made from durable copper alloy, they provide the solid electrical connection needed to push high amps without overheating the tip. Unlike generic replacements that might have loose tolerances, this genuine ESAB part fits your A6 head perfectly, ensuring the wire is guided straight and true. This helps prevent keyholing and ensures the wire exits the nozzle exactly where you aimed it.

Whether you are welding thick plate, structural beams, or large diameter pipe, downtime is the enemy. Keeping a stock of these contact jaws on hand means you can perform quick maintenance right on the gantry or tractor without long interruptions. They are designed for easy installation, so you can get back to welding fast. Don't let a cheap consumable compromise a critical weld; stick with the parts designed for your machine.

This jaw works for both standard SAW wire and automated MIG setups using the A6 head. Check your wire diameter and head configuration to ensure this is the correct match for your specific setup, but for many A6 users, this is the standard jaw for reliable daily operation. It’s a small part that plays a huge role in the consistency of your bead appearance and penetration.
