Welding???
rollazuki:
Dont Buy Gasless
Buy one with gas, or one that can be converted to gas. Buy at least 150 amp. buy one with a fan.(at least it reminds you its switched on when you lock the garage up, whirring away!)
Buy LOTS of wire, and get a gas bottle. The little tiny ones last 2 minutes and cost the earth!
Get lots of scrap steel, and P R A C T I S E.
Theres videos, and many books to help teach you how to weld, better bet is to get a welding mate to show you the basics, then practise.
Cut your practise welds apart and check penetration. Beat the hell outa them with a BIG hammer. If the weld breaks, its your fault, if the steel tears, then the weld was good.
Above all, Practise. Its actually pretty easy.
Good luck.

COULDN'T AGREE MORE don't go for less than 150 amp and use argo shield keep practicing until you can weld uniform straight lines try welding you name in a piece of steel and look at the back for the penetration. Good penetration is essential. Should sound like your frying bacon not a spitting cackle.
Cheers.

I bought a 150 Amp version of this
Not a bad little thing and while i do prefer to weld with gas on a mig i didnt find it too bad using it gasless
Cheers

I have the same welder but mine is 130amp:

This welder is now available to buy in B&Q but they want £150 for the 130amp one. I understand the more amps you get the more stronger it is i.e. it welds thicker metal together but Richard and I were only using the power settings on mine at about 3/4 strength and that was fine for the wheel arch and the rear floor boot replacement so I say 130amp would be a starting stength to go from :wink:
I'm probably wrong and no doubt will be told so in a mo but thats advice :lol:

WHY?? just posting "don't do this" isn't very helpful. What are the pro's and cons? Anyone can do the "just say no" routine but a bit of information would be a lot more helpful rather than uninformed personal opinions.

Why Chassis rails are 2mm thick and body work is either aluminium or less than 1.5mm mild steel. A 90amp welder would handle these thicknesses. Though I agree a larger welder is better and less likely to be operating at full capacity so less likely to overheat. for a diy/hobby welder that's only gonna be used once every blue moon 130amp is more than enough.
This is the one I bought. http://www.screwfix.com/app/sfd/cat/pro.jsp?id=72403&ts=25301#
