New tungsten electrode grinder from Huntingdon Fusion Techniques

on electrodes that have been ground incorrectly. Savings can be achieved because of the increased life of properly ground tungsten electrodes. With a special collet accessory, shorter tungsten electrodes can be held, increasing the length of life of each tungsten electrode before it is discarded. With ground and polished tungsten electrodes, mechanised welding can produce identical, repeatable results. The shape of the tungsten electrode is also important in manual welding: with a correctly shaped tip, the arc can be precisely positioned with none of the preferential arcing experienced when using poorly shaped, manually ground tips.

ENSURING tungsten electrodes are sharpened correctly can help improve weld quality. Tungsten electrode grinders are a convenient, accurate and safer way of grinding tungsten electrodes. Huntingdon Fusion Techniques (HFT) has reinitiated the manufacturing of the TEG-2 tungsten electrode grinder, which it retired from its product range a number of years ago, under the new name TEG-1000. HFT’s GeorgiaGascoyne commented, “Since we stopped manufacturing the TEG-2 tungsten electrode grinder, we’ve been inundated with requests to bring it back into our product range.” TIG welding requires tungsten electrodes to have perfectly ground and polished tips. The TEG-1000 grinder gives repeatable tungsten electrode points, enabling consistent repeatable arc performance and welding results.

The TEG-1000

Sizes 1 to 3.2mm can be ground as standard, with other sizes catered for on request. The diamond wheel grinds the tungsten electrodes longitudinally, preventing arc flicker or wander caused by circumferential lines or ridges found
