0700300377 - ESAB M8x30mm Heavy Duty Contact Tip for 0.045 Wire

Heavy-Duty Reliability for ESAB MIG Guns

Keep your production line moving and your welds consistent with the ESAB 0700300377 Contact Tip. This is a Heavy Duty (HD) replacement tip designed to fit ESAB MIG guns that utilize M8 threaded consumables, such as the PSF and MXL series. When you are welding with 1.2mm (0.045") wire, the contact tip is the critical transfer point for welding current. Using a high-quality tip like this one ensures that the power source's energy is efficiently transferred to the wire, resulting in a smooth, stable arc and deep penetration.

What sets this tip apart is its CuCrZr construction. Unlike basic copper tips that wear out quickly under the heat of industrial welding, this Copper Chromium Zirconium alloy is built to last. It withstands the extreme heat of the welding arc without softening, which means the hole stays round and the wire feeds smoothly for much longer. This translates to fewer tip changes per shift, less downtime for your operators, and lower overall consumable costs in the long run.

Whether you are fabricating structural steel, repairing heavy equipment, or running a manufacturing line, reliability is key. A worn contact tip can cause erratic wire feeding, arc stuttering, and frustrating burn-backs that ruin gas diffusers and liners. By upgrading to the ESAB M8x30mm HD tip, you are investing in smoother operation and better weld quality. This tip is sold individually but is an essential stock item for any shop running 0.045" wire on ESAB equipment.
