Depends on the machine, who made it and what is the amp on it.

Some sell for big dollars if complete, others are junk.


Is it possible for you to test it out?

What brand is it? I have a Lincoln high freq box. You can turn a arc welder into a tig welder with it. The electrode terminal of the arc welder goes into the HF unit. The tig torch connects to the output of the HF. Mine uses a 3rd connection to the work terminal of the welder.

dayton hi freq box

Not tryin to hijack anyone's thread, but ive got a
Dayton (granger's brand name) hi freq box I dont need anymore.
I believe its made by century, but i could be wrong.
A friend of mine needed some cash, so I bought it from him.
hooked it up & played with it once, and put it on the shelf.
If anyone's interested, let me know.

Hmmmn, no, mine is red and about 6" tall. I think the basic circuits are the same. They have a very simple spark gap transmitter to generate the high voltage/ high frequency.

Mine has a small circuit board with 4 transistors and one ic to control the gas flow and the hf start/stop. I reversed enginered it to produce a schematic so I can fix it if the board fails.

The manual on mine is Lincoln #IM-298-A

Interesting .. does yours look more like this ?

Jack, did you get the mail that I sent?

[Mike W]

Jack, it is about that size but looks more sofisacated. The input and output leads connect on the right side. That one looks like some thing I would build.
