Esab 37290 Contact Tip M 045 5 Pack

Product Description

The ESAB 37290 is an M 045 contact tip designed for MIG welding applications. Contact tips are consumable copper components that transfer welding current from the gun to the wire electrode as it feeds through the tip bore. The 37290 is sold in packs of 5 and priced per each unit, making it straightforward to stock for ongoing job site or shop use. At 0.2 pounds per unit and compact dimensions, these tips are easy to carry in a welder's kit. Licensed welding professionals and fabricators performing MIG or wire-feed welding will find these to be standard replacement consumables.

This contact tip is suited for wire-feed welding setups where the .045 inch wire diameter is the standard consumable size. It is commonly used in structural fabrication, HVAC sheet metal work, and general manufacturing environments. The M 045 designation indicates a metric-thread base and a .045 inch bore, and it is intended for use with compatible ESAB MIG welding guns. Each pack contains 5 tips, allowing technicians to keep spares on hand to minimize downtime during extended welding operations.

Installation Notes

Contact tip replacement should be performed by a qualified welder or welding technician with the welding machine powered off and the gun cool to the touch. Use the appropriate tip wrench to remove the worn tip and thread in the replacement until snug — do not overtighten, as this can restrict wire feed. Ensure the wire liner and drive rolls are in good condition before returning the gun to service.
