MIG OR ARC
Guardian.:
YOU ARC IT MATE YOU WILL HAVE A SIV EFFECT DISCO IN NO TIME AT ALL.
HAS TO BE MIGGED REALLY, STILL HAS TO BE SET UP ABOUT RIGHT AND USED ABOUT RIGHT, BUT BASICALLY, IF YOU CAN HOLD THE TORCH AND MOVE IT ABOUT, YOU CAN MIG WELD.
boss:
depending on where you are i would be willing to give you a crash course in welding :). i am a fully qualified welder in arc, mig, tig, ox/ac and alluminium :shock: .....any one want to give me a job???? :lol: :lol: :lol:
there is nothing wrong with arc welding, most structural members are welded by arc. as was said before its because its better at welding thick materials. it is not as strong a a mig weld(again depending on the application) because the flux is a coat around the electrode. its also alot easer to maintain, all you need is an inverter and a pack of welding electrodes but if your car has an arc weld on it it wont get though its MOT(or so im told)
mig units require alot more attention. granted the spool of wire lasts for a long wile but theres nothing more anoying than it running out of wire. also the gas is.....not difficult to get hold of but its hard to find something that will provide a good flux, alot of people think that pub gas co2 is a good replacement for argoshield but at the end of the day, its not! what alot of people forget is that when welding with co2 you need to keep a heater on it, i dont remember why because im an argoshield man! HA! but as was stated when mig welding it is a case of pull the trigger and go!
TIG welding is not something you wnat to go into its an expencive business and its not easey
there is also gassless MIG this gives you the best of both worlds between arc and mig, there is a spool of flux coated mig wire so you need not worry about gas. technecly its an arc welder....but its not its a mig. wolfonline are selling a no gas mig (130A) with helmet and gloves for £109.99 inc shipping i would go for that it you want the easey option
as i say i will be willing to show you whats what...im not really doing much myself apart from waiting for the college to sort my apprenticeship out.
PM me and let me know what you think.

MIG is easier because it's D/C so you can work with a smaller arc, arc welding is A/C so tends to favour biger welds that would burn through 1mm steel. I've tried it, it wasn't pretty and I used to be a good welder :wink:
TIG is the best of the bunch if you can afford it. Think professional quality. My mate uses it restoring MGs because it involves less heat than MIG so less distortion. It's a bit like an electric version of Oxy-Acetalene welding though, you have to stir the weld pool with a welding rod. Oh, and if you freeze the tip to the workpiece you need a new tip :(kerching):
For us mere mortals, MIG all day long.
peasey:
thanks for the replies lads you have all been really helpfull and explained it all really well so after christmas im going to invest in a mig welder and boss you are the man!!!!!ill give you a call after the frame work has been removed from my leg and i have got my new toy to weld thanks again lads,cheers

when my mate bought his 300 tdi he found it needed both rear arches / sills / and both front inner wings now he had been quoted £300 for one rear arch so i bought a clark te 135 its a gas mig for £200 i chse this one as it has a built in cooling fan nothing like stop start welding for a crap job but the fan means you just start welding and stop when the jobs done its also got variable power so you can weld from 1mm-4.5mm with ease
