Neutrix Portable Tungsten Grinder Parts FAQs
Answers to the questions buyers ask when choosing and fitting replacement parts for a portable tungsten electrode grinder.
Why does grinding direction matter when sharpening a tungsten?

The grind marks should run lengthwise along the electrode, from the shank towards the tip. Trade guidance on electrode preparation says marks running around the electrode form ridges that the arc can follow, so it may wander, while lengthwise marks help the arc start straight and stay stable.
A grinder that holds the electrode in a clamp and presents it to a flat wheel face does this for you. If the arc will not settle, check how the electrode was ground before blaming the welder.
How do I know which spare part I need for my portable tungsten grinder?

Start with the grinder's model and type, which are on the data plate or in the manual's parts list. Makers recommend original spare and wearing parts, and parts lists are written model by model, so a part that looks the same may not fit.
Compare the part number in the manual with the one you are ordering. If the part is a clamp or holder, also note the electrode diameter it is made for. Our team can help you match a part if you are unsure.
Why is there a separate clamp for each electrode diameter?

Maker instructions explain that each electrode diameter has its own clamping sleeve or clamp, so that the electrode is held securely and in the right position. A clamp that is too large lets the electrode move or tilt, giving an uneven or off-centre point. One that is too small will not take the electrode.
Check the diameter marked on the clamp and match it to your electrodes. A clamp that no longer grips squarely should be replaced.
What does the eccentric or position plate do?

On some grinders a plate or cam moves the electrode between different grinding positions or tracks on the wheel. Makers describe this as a way to spread wear across the wheel, which can extend the life of the diamond surface.
If the plate is worn or loose, the point may come out off-centre or at the wrong angle. Replace worn plates with the part listed for your model and check the result on a spare electrode afterwards.
