You have to run portable tools through a 110v centre tap to earth transformer in UK if in connection with a trade. (Mr Joe Public can use 220v equipment though)
rtbcomp is right, plus, where I want to weld on site we only have a 110v supply. I'd need about a 200ft extension lead for 240!!!
The Clarke 130 sounds good, although I've spoken to MM and they reckon they can't supply it.
I've found a Cemont MIG130 at telfordgroup, it says the current range is 30-120A, does that sound any good? Also my local tools place has got back to me with one, but i'm waiting to find out details on what it is.
Thankyou for your help with this, it's much appreciated
On-site under the 17th edition 110V CTE is preferable but 230V with mutable RCD protection can now be used (e.g. RCD protected circuit the RCD plug or socket). But if there isn't 230V 110V is still needed. You can run a portable TRX backward to get 230 from 110V but thats more theoretical. Try RS they have a TRX that is suitable.
Mike - are you sure about doing pipework repairs with a mig? It can be very difficult to get sound/ tight joints with mig, especially a small set. I'd really go for the stick if I were you - more difficult to do, but easier to do well, if you get my drift.
Edit - hold that advice. I've re-read your post and it says "dust pipework". - so it's for air, and it's thin. Mig will be fine matey.
Mind you, if it's galvanised, you should take off the galv first.
I'd pop rivet patches on though. Spot of silicone sealant, bob's yer uncle.
I think I saw a 110v mig on migtigarc website not long ago, think it was a butters set...
Not sure what your supply is, but I don't expect it will run from a normal box. We needed to use 32amp connectors and fairly hefty cable, taking power from a big site box.
have you got 3ph outets? could be an option to take a 240 from that...? then a nice little 240v set like the keppi miniarc.
