OVERVIEW

Protect Your MIG Gun with Reliable Insulation

Don't let a small part cause big problems in your welding shop. The Tweco 1360-1400 (34CT) Nozzle Insulator is the unsung hero of your MIG gun assembly, standing guard between your gas diffuser and nozzle. When you are in the middle of a long bead, the last thing you need is a short circuit caused by a worn-out insulator. This convenient 2-pack ensures you always have a spare on hand, keeping your downtime to a minimum and your arc burning steady.

Designed specifically for the popular Tweco No. 3 and No. 4 series MIG guns, these insulators are built tough. They are crafted from heat-resistant fiberglass that can take the punishment of daily welding, resisting the buildup of spatter and the intense heat of the arc. A fresh insulator not only prevents electrical shorts but also helps maintain the concentricity of your nozzle, ensuring smooth gas flow and cleaner welds.

Whether you are a professional fabricator or a serious hobbyist, maintaining your equipment is key to quality results. Worn insulators can lead to erratic arcs and damaged nozzles. Swap out your old, charred insulator with a fresh 34CT from this pack and experience the difference in reliability. Compatible with a wide range of Tweco-style setups, this is an essential addition to any welder's consumables kit.
