  • Threaded connection fits Tregaskiss TOUGH LOCK systems
  • Heavy-duty copper tip handles 0.035 in wire
  • Tapered shape supports MIG welding consistency
  • Compatible with G1, G2 and TA3 models

Tregaskiss Tough Lock Contact Tip

This tapered contact tip is manufactured by Tregaskiss for MIG welding guns that accept the Tough Lock series. It fits G1, G2, TA3, ThruArm G2 and Robotic CA3 models as well as BTB, Clean Air and TGX series guns. The heavy-duty copper tip uses a threaded connection for secure installation.

Suited for 0.035" wire MIG setups

Welders running 0.035 inch diameter wire on compatible Tregaskiss guns will find the correct fit here. Shops using a different wire diameter, a slip-on tip style or a non-Tough Lock diffuser should select another tip.

Threaded 0.035" heavy-duty copper tip

The tip accepts a maximum wire diameter of 0.035 in and features a 0.31 in outside diameter with threaded attachment. It is designed for use with gas diffuser numbers 404-14 and 404-18.

Questions about this item

How often will the 0.035" copper contact tip need replacement during heavy MIG welding?

The heavy-duty copper tip resists wear longer than standard tips, but replacement frequency depends on wire feed speed, duty cycle and spatter levels in your specific application.

What limits continuous welding with the threaded 0.31" OD tip before it must cool?

The copper tip transfers heat efficiently, yet sustained high-amperage MIG runs will eventually overheat the tip body, requiring pauses to prevent wire feeding issues.

How much heat does the tapered tip generate when running all day on a Tregaskiss G1 or G2 gun?

The tip itself does not generate heat; it conducts welding current to the wire, so tip temperature follows the gun’s duty cycle and amperage setting.
