0215503601 - ESAB PSF 405/505 MIG Gun Insulating Collar

Restore Your Torch Performance with the ESAB Insulating Collar

Keep your ESAB PSF 405 or PSF 505 MIG gun in top fighting condition with the ESAB 0215503601 Insulating Collar. For professional welders, the condition of the torch's front-end consumables is directly linked to weld quality and ease of operation. This insulating collar is the unsung hero of your MIG gun assembly, providing the necessary electrical isolation between the electrically live contact tip/neck assembly and the outer gas nozzle. If you have noticed arcing between your nozzle and the workpiece, or if your nozzle is becoming difficult to seat correctly, it is likely time to replace the insulating collar.

Designed to withstand the intense heat of high-amperage welding, this genuine ESAB part resists cracking and charring better than generic substitutes. A compromised insulator can lead to erratic arcs, poor gas coverage due to misalignment, and even permanent damage to the torch neck if the nozzle shorts out. By replacing your worn collar with the 0215503601, you ensure that the gas nozzle remains electrically neutral, allowing you to rest the nozzle on the workpiece when necessary without sticking or flashing.

Installation is straightforward and should be part of your regular torch maintenance routine. Simply remove the gas nozzle, unscrew the old collar (if threaded) or slide it off, and seat the new one in place. Inspecting this part every time you change your contact tip is a good habit that can save you from mid-weld failures. Whether you are fabricating heavy structural steel or performing precision repairs, trusting genuine ESAB components like this insulating collar ensures your equipment won't let you down when the hood is down.

Why Replace Your Insulating Collar?

• Prevent Shorts: Stops the gas nozzle from becoming electrically live.
• Heat Resistance: Withstands the thermal cycles of heavy-duty MIG welding.
• Proper Fit: Ensures the gas nozzle sits concentric to the contact tip for optimal gas coverage.
• Safety: Reduces the risk of accidental arcing to the workpiece or fixtures.

Don't let a small, inexpensive part compromise your weld quality. Keep a few ESAB 0215503601 Insulating Collars in your toolbox to ensure your PSF 405 or 505 torch is always ready for action.
