Tweco Type HD Contact Tips

Replacement contact tips for the popular Tweco No. 2, 3,& 4 type MIG torch.

In MIG welding the contact tip is where the welding current is conducted onto the wire and as such must have good contact with the wire to ensure a reliable current flow.

Over time, as the wire passes through the tip, the bore of the tip wears and enlarges leading to poor contact.
Therefore the contact tip is considered a wear part and should be changed periodically.
