OVERVIEW

Keep Your Tri-Arc Torch Running Cool and Safe

When you are deep in a gouging job at the foundry, the last thing you need is your equipment failing due to worn-out insulation. The Arcair 94-378-344 HD Upper & Lower Insulator Set is your solution for rebuilding and maintaining the legendary Tri-Arc 1" gouging torch. These aren't just plastic parts; they are heavy-duty thermal shields designed to take the punishment of high-amperage carbon arc gouging. If your torch is showing signs of arcing where it shouldn't, or if the current insulators are cracked and chipped, it is time for a swap.

This kit comes with everything you need to replace the critical insulation points on your torch head—both the upper and lower sections. The "HD" designation means these are built tough, formulated to resist the intense radiated heat from the arc and the physical impact of swapping out large 1-inch carbons. Installing fresh insulators restores the electrical isolation of the torch, ensuring the current goes exactly where you want it: into the metal you are removing, not arcing out to the handle or other parts of the assembly.

Don't risk your safety or the longevity of your expensive torch body with makeshift repairs. Using genuine Arcair replacements guarantees that the parts fit right the first time, letting you get back to work faster. Whether you are doing pad washing, defect removal, or general foundry cleaning, a well-maintained torch is a safe torch. Keep a spare set of 94-378-344 insulators in your tool crib so you are never caught off guard by unexpected wear and tear.

FAQ

The package typically includes one heavy-duty upper insulator and one heavy-duty lower insulator designed for the Tri-Arc torch.

No, this insulator set is specifically designed for the Arcair Tri-Arc foundry torch, particularly the model configured for 1-inch electrodes.

'HD' stands for Heavy Duty, indicating the material is formulated to withstand higher heat and physical stress than standard components.

Insulators should be replaced if they show signs of cracking, deep pitting, carbon tracking, or if the torch begins to arc internally or to the handle.

These are specified for the 1" Tri-Arc. While some body parts are shared, always verify the specific part number against your torch's breakdown diagram to ensure fitment.

Installation requires partial disassembly of the torch head. Remove the screws holding the body halves or jaw assembly together, replace the old insulators, and reassemble ensuring all fasteners are tight.

Genuine parts ensure correct dimensional tolerances for electrical safety and are made from materials tested to withstand the specific thermal loads of Arcair gouging processes.

Indirectly, yes. Damaged insulators can cause overheating or stray current, effectively reducing the safe operating limits of the torch. Fresh insulators help maintain optimal performance.
