The XTRWELD 15H-35 is a standard MIG welding contact tip designed for 0.035 inch diameter wire. It is manufactured to Tweco 15H Series specifications and serves as an OEM-quality replacement consumable for MIG welding guns rated at 500 amps. Contact tips of this type thread into the front-end assembly of a MIG gun and transfer welding current to the wire as it feeds through. Welding technicians and fabricators replace these tips routinely as part of scheduled consumable maintenance to maintain arc stability and wire feed accuracy.
This contact tip fits Tweco-style 500A MIG guns, including configurations compatible with the Classic Weldskill gun design. It is suited for production welding environments, fabrication shops, and maintenance welding applications where 0.035 inch solid or flux-core wire is in use. The part number and wire size are marked directly on the tip for quick identification during changeover.
Designed as an OEM-style replacement contact tip for Tweco-style 500A MIG guns compatible with the 15H Series front-end assembly, including Classic Weldskill style configurations. Brand names referenced are for identification purposes only.
Contact tip replacement is performed by welding technicians as part of routine gun maintenance. Always power down the welder and allow the gun to cool before removing the nozzle and worn tip. Use appropriate contact tip pliers or a wrench to avoid cross-threading the replacement tip into the diffuser. Inspect the gas diffuser and nozzle for spatter buildup during each tip change.
