Mig welder ?

[just cruizin']

why would you use the potential between phase and nuetral to point that out, most simple 3 phase welders would not use a nuetral. The only reason for a nuetral to be present in a 3 phase welder would be for use in a 240v control circuit. chimpboys sinusoidel wave forms look to be right to me, there is 120* between phase's.

Pinball i thought you were an electrician????? if you want to run 2 phase in a house you can get 2 phase supply from energex, conditions of supply and metering require that any premise with a calculated maximum demand of more than 70amps have the load split up over two phases, but try balancing the load evenly and you will find it easier to get all 3 phases and balance the whole house

Exactly my point, they use the potential between two phases to produce 415V, but you need all three because of the 120* misalignment between phases to achieve 415V. I agree why get two phases connected rather then three, might as weel connect it just in case you want to get a big welder, air-con etc.

I prefer Migo-mag welders but i bought a Weldmac 245 second hand from a steel fabrication factory that was re-newing all their equipment. I paid $500 for it. It appears to have done very little work and has a new Binzel hand gun and lead.

We use 315 Migo-mag welders at work and in the last 3 years the only thing that has been replaced other than consumables on either of these 2 units has been the hand guns as they generaly just wear out. Other than that they have had no work at all. One would do maybe 5 hrs a week and the other would do around 20hrs a week. My old man has a Migo-mag 195 that is at least 20 years old and is still going strong.

See these are the kind of deals that I just can't find. Well done!

If it makes you feel any better i bought it around 2 years ago and its done about 10min work since then I didnt realy need it but at that price i wasnt going to say no.

I personally have a 255 amp Lincoln welder, with remote wire feeder. I bought it second hand from a welding supplies company my work deals with. It had seen bugger all use as it was the only welder setup for steel work in a custom alluminium fabrication factory

It came with a 6 month warrantry on transformer for $1300 inc GST and besides consumables and gas I have not had a single problem with it.

If you can afford it get the remote wire feeder!

I have a unimig 195 which was about $1095 or there is the 240 amp version for about $1300 Im no pro by any means but to me it seems all good with heaps of digital settings that let you ajust to get the hang of it

So I imagine that thing is just sitting there in your way collecting dust. Why don't I take it off your hands for you so you can have some precious floor space back?

I am, although i find it better to forget that a lot of the time here, same as i forget i'm a safety professional.

As you say, run 3 phase it's cheaper than getting two phase, balances better, gives more flexibility to pluggin stuff in and energex are likely to be more amenable.

Besides it's fun playin dumb and dripping sarcasm occassionally.
