Miller Threaded Contact Tips PK5

These Miller Electric contact tips come in a pack of five and feature a standard threaded connection. They are designed for use with Miller Spoolmate series guns including the Spoolmate 250 and Spoolmate 3545 models. The tips accept aluminum wire up to .047 in diameter.

Suits owners of compatible Miller Spoolmate guns

Welders running aluminum wire through a Miller Spoolmate 250 or 3545 will find these standard duty tips match the original equipment. Shops using different gun brands, wire types other than aluminum, or wire diameters larger than .047 in should select alternative tips.

Critical spec is .047 in maximum wire diameter

This figure determines whether the tip matches your welding wire. Exceeding this diameter will prevent proper feeding and contact. Verify your wire size against this limit before fitting the tip to the gun.

Questions about this item

How long will a 199389 contact tip last when feeding 0.047 in aluminium wire all day?

The tip is rated for standard duty with a maximum wire diameter of 0.047 in for aluminium; actual life depends on amperage, stick-out and how clean the wire is.

Does the 199389 tip run hot or need extra cooling during continuous welding?

It is a standard-duty threaded tip for Spoolmate 250 and 3545 guns; heat build-up follows the gun’s duty cycle rather than the tip itself.

Which MIG gun and diffuser must I already own to use these PK5 tips?

They fit Spoolmate 250 and Spoolmate 3545 guns and require gas diffuser 199390.
