brazing

Instead of brazing can you use an arc welder like this one:

Yes u can use ark welding that what they do to seal the dome on a compressor.

Nice and cheap, you should give her a try ;)

It would be very interesting if this works because normal torches and the gas needed for it are too expensive for many people.

oh ok thanks guys i'll give it a try

[Jort]

and how your going to braze copper with it :s

[devok]

i dont know yet, i'll figure it out, or ask my father

[wdrzal]

you can only electric weld copper with a TIG welder, maybee he posted the wrong pic.

[devok]

cant you do it with an arc welder? (not TIG)

[wdrzal]

nope

[wdrzal]

while copper can be tig welded, for the application of joining copper tubes its a very poor choice.In fact probably the worst. First, tig welding requires a very high skill level, second even the best tig welder would have extreme diffuculity welding small diameter tubes like used in phase change. Third a good tig is expensive and a cheap one will not have advanced wave and current control making it even harder to produce a good weld with.

stick to gas welding (brazing)for refrigeration tubes.

oh ok
