Bit late for this thread I know (phone went down a while back- hundreds of meters of cable had been dug up and stolen down the road from my exchange. Probably on it's way to a certain nearby EU country by now!)
Any road up- Just wanted to put in a plug for the good ol' British Post Office...
Been playing today and set up the cutter for a try out. Hells teeth aint plasma cutting great! I've had plenty of experience with oxy-acetylene cutting but this is a whole different ballgame. As different as a scalpel and a machete.
Thought I'd make a few comments on the Cut 40 machine as I've...
Was looking at that machine on ebay myself but decided against bidding as I couldn't find any info at all on the net and that's usually a sign that it's a very rare creature you're dealing with. You may strike lucky but you really need a reliable source for consumables so I'd be inclined to take...
Benefit of the doubt?
Just to report that the cutter arrived Tuesday as promised. All present and correct and all fittings/ spares included. Yellow not the pretty red in the advert but hey!
Guess it's maybe time to ease off and wait for the body of evidence to accumulate on this company. Jugs...
Well I can see both sides of this conundrum but overall I think the moderation was absolutely correct. I've noticed another case on here of a 'poster' apparently working for the company who's products he was singing the praises of (think it was Draper migs but I could be wrong cos I'm very old!)...
Been looking at plasma cutters and came across the following terms and conditions for a Chinese seller.
1.The warranty period is two years; we will provide free parts for repair, but it does not include the staff maintenance services.
2. Before leaving the factory, each welding machine is...
Yup thanks- you're absolutely right. Dismantled switch again and painfully slowly reassembled making sure each element switched sequentially as I went. Took readings of resistance from common connection on chocolate block all along the row and it increased at each connector. Wired the switch...
Absolutely right. Maybe should have thought longer but since I couldn't turn the thing I couldn't test continuity to note what the switches were doing at each step so figured I had no option. Odd thing is once I'd put it back together without finding anything wrong (thought the innards would be...
Seem to be spending a lot of time here just recently! Picked up a Britweld 195 mig today which was described as having 'not much control at low settings'. Got it home and removed side panel and found a few wires have been getting warmish. Ripped out the burnt ones and replaced with the intention...
Thanks Drains. Kinda thought that would be the case but the pic on @bay (item 110600990334) makes it look like the coating is a dullish copper colour rather than the usual shiney surface so thought it might be something special.
Cheers

Hi,
Can anyone shine a light on this mig wire- SIFMIG A18 COPPER ALLOY MIG WIRE.
Don't know if this is a special type of wire or if it's just a fairly standard mig wire with a confusing title. Described as copper coated, deoxidised steel wire for semi automatic welding. Is it special in any...
No my hands are always itching to take things apart and play with them. As I said I wasn't desperate to change the diodes but just thought it would be worth looking out for spares while I'm scouring ebay. Sometimes real bargains do come along. My SIP is actually welding pretty well but I still...
Thanks guys. Amazing isn't it that what would seem to be a fairly simple 'current/voltage in a circuit' type question actually involves so many parameters when you look at all the components and variables in a welding machine. Hadn't even considered the inductance or capacitance although the...
Wonder if one of the techie types might be able to answer a question about the rectifier diodes in a MIG welder.
My welder has a centre tapped secondary main transformer and each end of the winding has a rectifier diode. The outputs are then joined together and supply the torch etc. The centre...
Been a while but just thought I'd let you know that I finally gave the SIP a quick try today and was pleasantly surprised. Only laid some runs on a length of scrap steel but not at all bad. I spent a good bit of time trying to get the Sealey 100xt useable and never did manage it. Eventually when...
Quick update:- Ebay seller hasn't answered my mails re the Topmig so must now compose a suitable negative feedback I guess.
Problem with power was that white wire which was floating around loose by the wire feed needed connecting to the torch power lead. There was no attachment point so I...
Thanks for the replies. Yes I know the valve should be part of the torch unit but it isn't on mine. Just has the electrical switch which connects a wire to the live torch. The handle is obviously moulded for this particular model so I can't fit a gas valve type into it.
Hadn't thought of a...
Just got a topmig 140 from ebay which was described as fully working and little used. After reading on here of the awful SIP wirefeed and being quite happy to carry out the mods suggested I decided I'd spend the time and get this machine sorted rather than spend three times as much on a better...
