OVERVIEW

Keep Your Foundry Running with Genuine Arcair Parts

When you are in the middle of a heavy pad washing or defect removal job in the foundry, the last thing you need is equipment failure. The Arcair 94-378-270 Heavy Duty Upper & Lower Insulator kit is your solution for maintaining the legendary performance of your Tri-Arc® gouging torch. Designed to take a beating, these insulators are built from tough, heat-resistant materials that stand up to the extreme conditions of metal removal. Don't settle for generic knock-offs that might crack under pressure; trust genuine Arcair parts to keep your production line moving.

Over time, the intense heat and spatter from gouging can degrade your torch's insulators, leading to safety hazards and poor performance. Replacing them with this heavy-duty kit restores your torch's safety barrier, protecting both the tool and the operator from stray electrical currents. This kit includes both the upper and lower insulators, giving you everything you need for a complete refresh of the torch head's protective shell. Whether you are using 5/8" carbons or pushing the limits of your equipment, these insulators ensure your Tri-Arc torch remains reliable shift after shift.

Maintenance is a reality of the welding and gouging world, but using the right parts makes it easier. The 94-378-270 kit is designed for a perfect fit, meaning less time fumbling with repairs and more time getting work done. By proactively replacing worn insulators, you prevent more costly damage to the internal brass and copper components of your torch. Invest in the longevity of your equipment with Arcair's heavy-duty replacement parts and maintain the high standards of safety and efficiency your foundry demands.

FAQ

This kit is designed specifically for the Arcair Tri-Arc® Foundry Gouging Torch.

The package typically includes one Heavy Duty Upper Insulator and one Heavy Duty Lower Insulator.

They are manufactured from high-impact, heat-resistant composite materials designed to withstand the abusive environment of foundries better than standard materials.

Insulators should be replaced whenever they show signs of cracking, deep pitting, carbon tracking, or significant heat damage to ensure electrical safety.

No, these are specifically shaped and dimensioned for the Tri-Arc series and will not fit standard K-series or Angle-Arc torches.

While the insulators themselves protect the torch head, they are compatible with the standard range of electrodes used by the Tri-Arc torch, including 5/8 inch carbons.

Typically, this part number refers to the insulators themselves. You usually reuse existing screws unless a separate hardware kit is purchased.
