Questions about this item

Will the 0.045 inch bore fit my Series 1445 Tweco-style gun?

Yes, the tip is made for Series 1445 guns and the bore is sized for 0.045 inch wire.

How do I install the copper contact tip without cross-threading it?

Thread the tip straight into the diffuser by hand until it seats, then snug with a wrench — forcing it at an angle strips the threads.

When should I replace a tip from this 25-pack?

Replace a tip when the bore shows visible wear or spatter builds up inside — copper tips wear faster at higher amperage.
