Default What is an arc stabilizer

I saw a craftsman "high frequency arc stabilizer" on ebay. What is that used for?

It's like the high frequency arc starter on a TIG welder. They are useful for starting and keeping an arc going when welding AC.

Here's some rather amusing Q & A from a guy who makes a modern version. Such as:

Q: Will it really ignite an arc without touching, even with my lousy welder?

A: Hell yes.

They were first used in older sine wave AC TIG welding power sources to
stabilize the arc as the voltage passed through 0 volts. Most AC machines
today still have them they aid in starting the arc and generally turn them-
selves off after the arc is started in square wave machines as they are not
needed.

Generally they are build in to modern machines. As a separate unit they are
mostly regulated to engine drive usage any more.

What model is it? If it is a Craftsman Brand it may not work well with other
brands of equipment.

Miller and Lincoln units are wired to be plug and play with the same color
machines.

The old Lincoln Idealarc 250 manual cautions that a HF bypass filter be installed to prevent damage to the main transformer. It may be built in to the better HF units.

I'm not looking to buy it or use it. I was just curious as to what it was for. So it is just for tig? I have never had a problem striking an arc with a stick. So I can tig with an ac machine if I had one of those?

And here's me thinking it is something that older welders take to stop a shaking hand.
