More ramblings: A weld circuit other than short circuit depends on ionized air to conduct electricity. Molecules and atoms won't remain ionized for long. A bolt of lightning travels in steps in high speed photography is turns in a series if steps surging and stopping as voltage builds,more electrici...

The manual tells me that the switch can go from no high frequency, to start arc only high frequency for stick welding, or continued high frequency for aluminum. I'm guessing the spark gap device shown in the manual is a way for the machine to set up fluctuation in the magnetic field. An engine (gaso...

Dialarc HF it is a water cooled tig machine, with leads for stick welding. It has a switch for high frequency. How high is this frequency. I believe my Diversion is set at 120 HZ It seems about 70% electrode positive.

I bought the dialarc. It is a monster. I haven't tried it yet. Cord and plug connections aren't readily available at 90 amps.
I may hard wire. You probably won't be tempted to move it. It has high frequency? It doesn't appear to give a way to adjust ac balance.

If you are interested in a good entry level machine, I have a 5 month old Miller 180 Diversion. For steel and stainless it is hard to beat. Aluminum requires a lot of heat! With 1/4" I haven't welded long before I start to push too far on the foot peddle as heat seems to be tapering off. I real...

I'm already outgrowing my new Miller Diversion 180. I'm thinking about upgrading. A dealer has a Sincrowave 250, at a much better price a private sale has a Miller Dialarc 250. The Dialark is a big machine with a great duty cycle. I'm unsure if it has the features I want. Can anyone offer advice?

Self taught I've burned up maybe a thousand pounds of rod,stick,wire, and coat hangers. I make no claim to expertise, I have successfully welded a lot of variety. Desperately wanting to weld aluminum sheet metal,I studied up on the best practice. I approached a friend who let me use a very expensive...

Are you sure they are 5/16? 5/8" is pretty common, and a lot more tolerant of heat.

I just got in to the forum for the first time. I guess it is coincidence that in the responses to a post are a bunch of pictures of a 1946 Jeep. I got and began work on my 1947 Jeep in 1969. The first order of business was cutting the cowl at the seam behind the fenders. The rear floor rust free bec...

My obsession with jeeps started early. When a not wealthy kid in Vermont hooked on Jeeps gets his first at 12 it will be rusty. In my case a 1947 bought in 1969. The first thing I built was a Jeep body. 44 years later my sons love it. It is still rust free. All I had was an acetylene torch. My fathe...

Thank You! You have used a number of descriptive terms to describe the welds produced by untrained beginners. I've made most of the mistakes. My first welded Jeep body was begun 44 years ago. Until now I've never had an opportunity to see how it should be done. It is a generous thing to give away kn...
