0808650882 - ESAB A2/A6 Contact Jaw 1.6mm x 73mm for Twin Wire SAW

Keep Your Sub-Arc Head Running Smoothly

When you are running a sub-arc tractor or a column and boom setup, the last thing you need is a contact jaw failure in the middle of a long seam. The ESAB 0808650882 Contact Jaw is the direct replacement for your A2 or A6 welding head when you are running 1.6mm (1/16") wire. This isn't just a piece of copper; it's the final transfer point for all that amperage you're pumping into the joint. If this jaw is worn out or ovaled, your arc stability goes out the window, and you start seeing defects in the bead.

This specific jaw is 73mm long and is designed for "Twin" setups, meaning it's built to handle the heat and duty cycle of high-deposition welding. Changing out your contact jaws regularly is part of the game in SAW. As the wire feeds through, it eventually wears a groove or keyholes the tip, which causes the wire to wander and the electrical contact to fluctuate. Swapping in a fresh 0808650882 restores that crisp, steady arc hiss you want to hear under the flux.

Installation is straightforward, fitting directly into the contact nozzle assembly of your ESAB head. Make sure to check your wire size before ordering—this one is strictly for 1.6mm wire. Using the wrong size jaw can cause feeding issues (if too tight) or arcing inside the tip (if too loose). Keep a few of these in your spare parts kit so you aren't stuck waiting on a delivery while the beam line sits idle.

Practical Tips:

• Check for Wear: Inspect the bore for keyholing every time you change a wire coil.
• Clean Connections: Ensure the threads and seating surfaces are clean when installing to prevent resistance heating.
• Match the Wire: Verify you are running 1.6mm wire; using this with smaller wire will cause arc instability.
