Q & A Guidelist

For Choosing the Correct Tungsten Grinder

Does it grind longitudinally?

This is a necessity.

Does it incorporate a diamond-grinding wheel?

This is a necessity.

How many electrodes can a typical diamond grind wheel make before requiring replacement?

The more the better. This also varies based on operator use.

If a cutting apparatus is needed, does it offer a diamond-cutting wheee with measurement apparatus?

Notching the electrode and hand breaking is not acceptable.

How short can the electrode be cut?

Match this condition to your needs.

What is the surface finish to the electrode after grinding?

20 RMS is fine for most uses, finer finishes are even better.

How quickly does it take to flat, grind, and cut different electrode diameters, angles, flats, and lengths?

It should sound simple and direct. Otherwise, it will take too long and become cumbersome.

What is the process the equipment operator needs to follow to complete one electrode?

It should be simple enough that all welders can repeat the process and produce the same electrode.

What tolerances can a typical operator expect to produce for the angle, length, and flat?

Match these to your needs.

Are accessories such as vacuum dust collection, on site carrying case, a wide variety of collets, etc. readily available?

Match these to your needs.

Is support readily available? What is the warranty?

Match these to your needs.

How expensive is it?

Expect to pay quite a bit more than an a standard bench grinder, but a good tungsten grinder will pay for itself over time with saved welding time, saved electrode preparation time, and improved welds.
