Astro_Al Posted January 4, 2008 Share Posted January 4, 2008 Whether or not it works, would it actually help? A larger machine will be demanding a certain number of amps per phase (on 3 phase), but you'd have to supply that all from your single phase supply if you expect the same output. Never mind using a 'blue' commando plug (16A) - you'll need a lot more than that! For example my 300 amp tig uses the best part of 64 amps running off a single phase. Hope it helps.

FridgeFreezer Posted January 4, 2008 Share Posted January 4, 2008 If it was that easy everyone and their dog would have done this, the manufacturers would've incorporated it into the machinery and almost no-one would buy 3-phase supply from the electric company. Sorry Rog, it's clearly b*ll*cks. Quote Link to comment Share on other sites More sharing options...

Al, Fridge - thank you (it was my thoughts - honest!) The reason behind my desperation: Here at work we have 3 mother of 3 phase migs going spare and one massive lincoln oil cooled arc welder. Im going to try and sell them on as they are taking space up, obviously they would have more value as single phase. Quote Link to comment Share on other sites More sharing options...
discojmz Posted January 4, 2008 Share Posted January 4, 2008 Rog, pm me a rough price on one of the migs. i have 3 phase here on the farm so im always on the look out. could do with something a bit tastier than my little 105amp mig. oh and the cyntringham bantam oil cooled arc Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted January 4, 2008 Share Posted January 4, 2008 As Al points out, you'd still need the mother of all electricity supplies - if it draws 64A from 3 phases it'll probably need 3x that, which pretty much rules out any domestic supply. If it involves re-winding the main transformer (which at a guess it does) then going from 415V to 230V you will double the current and you're then looking at silly things like a 400A supply at 230v, at which point the electric company slap you with a fish and tell you to stop being silly and install 3-phase Quote Link to comment Share on other sites More sharing options...

Astro_Al Posted January 4, 2008 Share Posted January 4, 2008 If you like, you can leave them in my garage and come and use them whenever you like! Sounds like a nice offer to me! Al. Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted January 4, 2008 Share Posted January 4, 2008 Al - why not start a welding shop, you seem to be accumulating welders anyway so may as well make some money Quote Link to comment Share on other sites More sharing options...

simonr Posted January 5, 2008 Share Posted January 5, 2008 If you note the text in the advert says it works on any machine which uses a transformer on the input. All he's doing is separating the three phase coils and applying mains to one of them. It will work on welders and some plant, but not on 3 phase motors - which rules out most lathes and mills.

Vanny Posted January 6, 2008 Share Posted January 6, 2008 my experience is that it will work on SOME motors, but typically they end up with no power and will only spin backwards slowly deffinatley snake oil. Quote Link to comment Share on other sites More sharing options...
Night Train Posted January 6, 2008 Share Posted January 6, 2008 It is possible to convert motors from 3ph to 1ph but as Vanny says they loose power. I do, however, look for 3ph machines for my workshop on the basis I have a small stash of big 1ph motors to replace on them thanks to a dad who hoards everything electrical. I think, generally, if you need that much power then 3ph really makes a difference, if you can afford it. Quote Link to comment Share on other sites More sharing options...
Guest mortus Posted January 6, 2008 Share Posted January 6, 2008 it is possible to convert 3phase to single phase, but you loose power... ofcourse. unless you use the mother of all caps then it could work... just not for very long. ive got 3phase anyways its good living on a farm. can you PM me about a rough price on one of those migs please? and where abouts are you in newark, your not too far from me i dont think.
