Don't need to Oz. I've been welding both professionally and otherwise for over 30 years, and know my way around the business pretty well. > Till then , again, you're living in your own world. > Wake up, look around. Sure Oz. Can you point me towards a store that'll sell me a "pulse mig"? :) -- Regards, Noddy.

Is that an RF welder? Reason I ask, an LAME acquaintence brought in a welder he used on a/craft once, to see if we could repair it (fat chance with no cct or marked components in the power-areas) It did have high voltage ceramic capacitors in it which I had only seen in transmitters of more than acouple of 100watts.

No, but I bet you do though :) You only need a welder's licence to do structural or pressure vessel welding, and there's plenty of welding that goes on that doesn't involve either. Not that we'd expect you to know anything about that :) > Hang on I'll look....any Lincoln dealer .... Got a model number? :) -- Regards, Noddy.

Such machines gave been around for a little while, and they're often used in aluminium fabrication work on anything reasobably thick where the welded joint needs to be pretty solid. Like Aluminium scaffolding for example. The advatnages of it are that it's *very* fast (way faster than tig), gives a good finish and is vastly superior to conventional mig welding of aluminium in produiction applications. It's also hideously expensive, and I'll bet my left knacker that it *ain't* the type of pulse mig Oz was talking about :) -- Regards, Noddy. |
