Precise Tungsten Electrodes Tips with the TEG-1000

Correctly preparing each Tungsten Electrode for welding is crucial. It is one of the most important variables in TIG / GTA welding and each Tungsten Electrode must be ground properly to improve arc starting, stability and subsequently weld quality.

Manufactured with a diamond wheel, the TEG-1000 Tungsten Electrode Grinder from Huntingdon Fusion Techniques HFT® will ensure the grinding of each Tungsten Electrode results in clean and smooth finishes, with no splintering and eliminating arc jumping. 

Luke Keane, Technical Sales Manager for HFT® said: “It is very important to have a dedicated Grinder for Tungsten Electrodes. This will help to ensure that the wheel and tungsten tip do not become contaminated during the grinding, which can possibly transfer foreign material to the weld.”

“An incorrectly ground Tungsten Electrode tip may drop into the weld pool and create a tungsten inclusion that could lead to a weld cut-out or reject, either way, leading to additional welding costs and lost time. It can also result in a huge reduction in tip life and changes in arc voltage.” 

The use of the TEG-1000 Grinder will give repeatable Tungsten Electrode points every time, enabling consistent arc performance and welding results. Sizes 1.0 to 3.2 mm can be ground as standard, with other sizes catered for on request. 

TIG welding requires Tungsten Electrodes to have perfectly ground and polished tips. HFT®'s TEG-1000 provides these, time after time, to exactly the same size and shape. The design of the TEG-1000 is such, that the diamond wheel grinds the Tungsten Electrodes longitudinally, preventing arc flicker or wander caused by circumferential lines or ridges found on electrodes, which have been ground incorrectly.

With Tungsten Electrodes ground and polished, mechanised welding can produce identical results every time. With manual welding, the shape of the Tungsten Electrode is just as important. With a correctly shaped tip, the arc can be precisely positioned with none of the erratic arcing experienced when using poorly shaped manually ground tips. 

HFT® also manufacture MultiStrike® Tungsten Electrodes that are designed to address the growing concerns about the radio-toxic thoria that is present in standard red tipped Tungsten Electrodes. MultiStrike® Tungsten Electrodes are non-radiotoxic, non-thoriated, non-carcinogenic. They will also strike 10 times more arcs than red tipped thoriated tungsten, when tested under identical conditions. Eliminate the thoriated dust in the atmosphere by changing to MultiStrike® Tungstens so that when there is tungsten grinding dust, it is not radiotoxic.

Low Cost Monitor for Welding Titanium and Stainless Steel

Titanium and stainless steel are both reactive alloys. When they are heated during the welding process, they will react with any air that is present, causing oxidation, which can lead to a loss of corrosion resistance properties. Shielding the metal with an inert gas is therefore crucial and one wa ...

Accurately Measure the Dew Point During Purging

During purging welders need to measure the oxygen content but also need to measure the ‘dew point'. The dewpoint is the temperature where condensation begins and water will condense on the material being welded. This can affect the weld properties significantly. Georgia Gascoyne, CEO for HFT® sai ...

Pipe Purging Monitor

What is Weld Purging? Weld Purging is the displacement of oxygen by an inert gas (usually argon) from the vicinity of a weld, before, during and after welding. It is crucial to displace the oxygen when welding many metals to help achieve oxide free, zero colour welds with no loss of corrosion resis ...

Reliable Oxygen Analyzer for Welding Titanium

When welding titanium, it is essential that the oxygen level surrounding the weld is purged down to as low as 50 ppm. Measuring the oxygen level with a reliable oxygen analyzer is the most efficient way to know exactly when to commence welding. Specifically designed for Purge Chamber welding, the ...
