  • Fits gas diffusers 404-14 and 404-18 for quick changeovers

Product Identity

This TREGASKISS 403-20-35 is a threaded copper contact tip built for heavy-duty MIG welding. It belongs to the TOUGH LOCK series and fits Tregaskiss G1, G2, TA3, ThruArm G2 and robotic CA3 guns as well as BTB, Clean Air and TGX series equipment.

Fit and Exclusions

The tip accepts a maximum wire diameter of 0.035 in and threads into Tough Lock nozzles used with gas diffusers 404-14 and 404-18. Welders who run thicker wire or use a different nozzle system will need another tip.

Deciding Specification

The critical figure is the 0.035 in maximum wire diameter paired with the 0.044 in inside diameter; only wire that stays at or below that size will feed correctly through this tip.

Questions about this item

How often should the 0.044" copper tip be replaced during heavy-duty MIG welding?

Replace the tip when the 0.044" bore wears oversize or the copper shows visible erosion; intervals vary with amperage and wire quality but a few hours to several shifts is common.

What is the first limitation that appears during continuous high-amperage MIG runs?

The 0.035" wire size and heavy-duty copper construction set the current ceiling; sustained loads beyond the tip's heat capacity cause accelerated bore wear and unstable wire feeding.

How hot does the threaded copper tip get when running all day on a TOUGH LOCK system?

The copper tip operates at MIG process temperatures; its threaded connection to 404-14 or 404-18 diffusers conducts heat away, but the tip itself will become very hot during continuous welding.
