W7004070 - Tweco Fusion 180 MIG Gun Replacement Trigger Switch

Restore Your MIG Gun's Performance

When you are in the middle of a fabrication project, the last thing you need is a finicky trigger on your MIG gun. The ESAB Switch Trigger for 180 Guns (W7004070) is the essential replacement part needed to fix intermittent connection issues or a completely broken switch on your Tweco or ESAB 180-amp MIG torch.

Over time, the mechanical components of a welding gun trigger can wear out from repetitive use, dust ingress, or accidental drops. A failing trigger often manifests as a delay in wire feeding, stuttering starts, or a failure to initiate the arc altogether. This genuine OEM replacement restores the crisp, responsive feel of a new gun, ensuring that when you pull the trigger, your welder responds instantly.

This specific switch is designed to fit the popular Tweco Fusion 180 and similar ESAB-branded 180A MIG guns often found on machines like the ESAB Rebel series or Fabricator units. Installation is straightforward, allowing you to swap out the defective component and get back to welding with minimal downtime. Trust in genuine parts to maintain the safety and reliability of your equipment.
