Tungsten welding electrode grinder
collects dusts
An updated version of a tungsten electrode grinding machine collects the radioactive dust produced when grinding thoriated tungsten electrodes for TIG welding.
Huntingdon Fustion Techniques (HFT) said that the latest version of its proven tungsten electrode grinder, the The Techweld TEG-3, collects the radioactive dust produced when grinding thoriated tungsten electrodes for TIG welding A key advantage of this new version, said HFT, is that the hazardous grinding dust is now expelled downwards, directly towards the vacuum collection point

Backing tape prevents weld failure
Backing tape used in the welding of seams or runs help to prevent weld failures and produce flat, slag-free welds requiring no grinding or backgouging.
Welding equipment maker moves to Wales
Huntingdon Fusion Techniques left its Huntingdon home on December 19 to relocate to larger premises in Burry Port in Carmarthenshire.
A clear Perspex window seals the front of the grinder, allowing the operator to inspect the grinding process, whilst protecting him or her from the emission of grinding dust.
Behind the window is a diamond wheel that produces perfectly ground and polished electrode tips necessary for TIG and plasma welding, says its British manufacturer.
While adding this Dust Collection system, HFT has further improved the design of the Techweld TEG-3 by moving the grinding head from the '3 o'clock' to the '6 o'clock' position.
The Techweld TEG-3 grinds electrodes longitudinally to eliminate the circumferential lines and ridges that cause arc flicker and wander, so that identical and repeatable results are achieved with mechanised welding.
* Precision positioning - the tip shape produced by the grinder allows precise positioning of the arc for manual welding without the preferential arcing that occurs with poorly shaped, manually ground tips.
"By grinding tips to exactly the same angle every time, the Techweld TEG-3 ensures consistent and repeatable arc performance and welding results," said Gerald Evans for HFT.
He added: "Accurately ground electrode tips last longer than those that are held against a workshop wheel or belt grinder by hand".
All common sizes of electrode from 1.6mm to 4mm are accommodated by the grinder's holding system and special requirements can be met.
An extra collet attachment for the holding block allows short electrodes down to 12mm in length to be sharpened to increase working life.
The Techweld TEG-3 has a diamond wheel that gives the equivalent of three man-years grinding life and is easily replaced.
A front cover prevents the grinding of other materials, to eliminate contamination of electrodes and transfer of unwanted elements to the weld-pool.
The grinder's high-speed motor runs from a 220V single-phase supply at 50Hz.
Servicing is available in most countries, and the drive motor has a lifetime guarantee. Request a free brochure from Huntingdon Fusion Techniques ...
