0815363007 - ESAB PSF 405 Replacement Cooling Tube / Swan Neck

Restore Your Torch's Performance

Is your MIG gun running hotter than usual? Are you experiencing erratic arcs or stuttering wire feed despite changing your liner and tip? The problem might be your cooling tube. The ESAB Cooling Tube (0815363007) is the direct replacement neck for your PSF 405 and compatible PSF series torches. Over time, the internal surface of the tube can become worn or grooved from thousands of pounds of wire passing through it, and the exterior can take a beating from spatter and accidental drops. When the neck gets damaged, it creates friction for the wire and resistance for the current, making your welding day frustrating and unproductive.

Built for the Heat
Welding generates massive amounts of heat, and this cooling tube is your torch's first line of defense. Made from heavy-duty copper alloy, it pulls heat away from the consumable stack, keeping your contact tip cooler and lasting longer. A cooler front end means less spatter adhesion and less downtime cleaning your nozzle. This tube is designed to withstand the thermal expansion and contraction cycles of heavy industrial welding without cracking or warping.

Smooth Wire Delivery
One of the most overlooked causes of bird-nesting and poor feeding is a bent or worn conductor tube. This genuine ESAB part ensures the correct angle and internal diameter for smooth wire transit from the cable to the tip. Don't fight your equipment; replace your worn cooling tube and get back to laying down smooth, consistent beads. Installation is straightforward, getting you back under the hood in minutes.
