Welding Tips
MIG contact tips from HYW Products. The contact tip is the small copper consumable that transfers welding current to the wire as it passes through the gun. Because it wears with every inch of wire, it's the most frequently replaced MIG part — a fresh, correctly sized tip keeps the arc stable and feeding smooth.

Frequently Asked Questions
How do I pick the right contact tip?
Match the tip to your wire diameter (stamped on the tip) and to your gun's thread/series. The wrong size causes erratic feeding, burnback, and arc instability.
How often should I change the contact tip?
Replace it when you see poor arc starts, burnback, or a worn/oval bore. It's a wear item — keep spares on hand.
