770840 - Hobart XT12R Plasma Standoff Guide and Cutting Tip Kit

Optimize Your Plasma Cutting Precision

The Hobart 770840 Standoff Guide and Cutting Tip Kit is an essential accessory package designed specifically for the XT12R plasma torch, commonly found on the Hobart AirForce 12ci plasma cutter. This kit is engineered to restore and enhance the performance of your plasma cutting system by providing critical replacement components that directly affect arc quality and consumable longevity.

At the core of this kit are two replacement cutting tips. These are not merely standard replacements; they feature an improved design over the previous #770795 tips. With a larger orifice and increased length, these tips facilitate superior plasma arc transfer. This results in a more stable arc, cleaner cuts, and improved efficiency during operation. For professionals and hobbyists alike, maintaining a sharp and properly specified tip is crucial for achieving the best possible edge quality on conductive metals.

The included standoff guide is equally important for the longevity of your torch parts. In manual plasma cutting, maintaining a consistent distance between the torch tip and the workpiece is challenging but vital. The standoff guide attaches to the torch and physically maintains the optimal gap. This allows for "drag cutting," where the operator can rest the torch on the workpiece and drag it along the cut line without the tip actually touching the metal. This separation prevents the nozzle from shorting out or overheating due to blowback, significantly extending the life of your consumables.

Whether you are fabricating custom parts, performing automotive repairs, or handling general maintenance, the Hobart 770840 kit ensures your AirForce 12ci operates at peak performance. By combining protection with improved arc dynamics, this kit reduces downtime and operational costs associated with frequent consumable changes.
