I am about to embark on the purchase of an electric stick welder. However someone told me welding machines are no longer legal to use on a private driveway where I would be patching the car.

Can someone clarify this , I can't see this being correct and can't find any info online.

Thanks

Dont know if its legal or not but I have loads of mates that use stick & mig at home, they've never mentioned it.
 
My nephew uses mig on his parents drive.
Illegal or not he has to keep the right side of mum. :eek:
 
I doubt it very much. That would effectively destroy the hobbyist welding market. Fewer people have garages to work in now and I can't see the law encouraging people into a confined space like that.

Both the main practical mechanic mags have buying guides on welding gear this month. I had a quick skim through both in Tescos 2 days ago and don't remember seeing any warning.

And Machine Mart say nothing here.

I tried it years ago and failed dismally. Thankfully Z3s rarely need welding. And if one of mine needed it I'd let a professional do it for the very small demand I'd ever have.
 
Just make sure you do everything reasonably possible to prevent anyone walking passed your drive getting "arc flashed". Make sure you put up adequate screens.
I'm not sure your household insurance would cover you against the "compo" mob.
 
If you're planning to weld on a car, MIG would be my first choice for almost any job (maybe TIG for exhausts), and certainly not stick....
 
I have used my cheap Machine Mart Clarke MIG welder extensively rebuilding cars - MGs and Triumphs do rust! I usually do it in the garage with the door open for some ventilation. Anyone walking past would be able to see the arc but I can't believe that it would harmful to anyone who is over a yard away. Please don't buy an arc or stick welder. All you will do is blow lots of holes in the thin metal. MIG is the only sensible welder for the home restorer, and although having a gas bottle is a bit of a nuisance I wouldn't get a gasless one. I use a large bottle of argon/CO2 from Adams Gas as the disposable cans last only a few minutes.

Indeed a classic mig setup with a 10L gas bottle is the way to start when it comes to automotive repairs (especially bodywork).
You can always get a used setup if cost is an issue.
Its also the easiest machine to work with (if you get your amp/wire thicknes/speed setup right)

Stickwelding is only good if you want to do agricultural stuff. Good heat penetration for thick steel constructions.

TIG will get you by far the most appealing welds (when thats an issue), has by far the most possibilities, but less suitable for bodywork. (and you need both hands!). So thats more of a specialty setup.
 
I did a term long evening class in welding. At the old Swindon railway works apprentice school, taught by a former railwayman master welder.

In summary, I was awful and couldn't get the hang of it. He was mesmerising and that was stick/rod/traditional whatever it is welding.

One evening we were told to bring our own items in to weld. I brought in a Mk I Escort exhaust manifold - this was 30 years ago ;) He took it off me and said it's best for me to do that (in other words you're cr*p and will mess it up). What he did was a work of art!

I'm tempted to give it another go, I was only 18 at the time. But I just can't think I'll ever need to do much of it on a Z3. Unless it was to repair the chassis on an accident damaged car. And that I would definitely leave to a professional!
 
Stick welder is cheap and simple bit of kit, however its no good for thin car bodywork panels (only 0.7 to 1mm thick), you'll just blow holes in it. Ideally its for metal at least 3mm thick and even then you have to be careful.
As mentioned above MIG is the best and then you'll need a bit of practice to get a reasonable result. Make sure you have lots of scrap to practice on before starting on the actual repair section!!

If you ever watched Wheeler Dealers that's what Ed China used for patching bodywork/chassis sections.

Before starting any welding take all the appropriate precautions, disconnect battery, fire extinguisher(s), fire blanket, remove flammable materials etc. Good preparation is paramount.

Finally if you have any doubts, let a professional do it!
 
When I first bought my welder I got some scrap body panels and had a go. The welds looked like bird droppings and that was when I hadn't blown a hole in the steel!:(. However, I have friend who is an expert welder and I said to him that I thought I had bought a cheap, rubbish machine. He came over one evening, had a look at the machine, twiddled the wire feed and set the current, and proceeded to produce a perfect weld first time. Once he had shown me what was possible, I learned how to do it, particularly how the wire feed setting is as important as the current setting. When I had finished welding my MGB GT (new sills, floors, boot floor etc.) and the local paint shop came to collect the shell for painting, the guys said "Did you do all that with that toy welder?" When I said yes, he offered me a job in his workshop! Maybe I should have taken him up on it.:)
 
For Mig welding the biggest problem most people have is a lack of preparation of the area to be welded. You have to get steel clean and shiny first and foremost and then have the two pieces being welded clamped or pressed together so there is no gap between them. Put a small "tack" every couple of inches and tap the joint close using a small hammer. DO NOT use a big hammer as it will only bounce the joint apart and do no good. This makes welding much easier. Practice, practice, practice and then practice some more. Also, be ready for the occasional visit to A&E for treatment for a welding flash because at some point I can gaurantee you WIIL have one!

I use an arc welder for heavy duty stuff and a gas mig welder for sheet metal / car body welding. For the gas I use a CO2 bottle I got from a local pub Landlord who gets it replaced for me when necessary on an exchange basis. No matter what I am welding I always set up the hose pipe and have it close by. The automatic welding masks are good any are cheap enough to buy.

I agree re the auto dimming welding masks but even these aren't fool proof. I used CO2 on mine as well, does the job once your a competent welder but much easier to learn using argon IMHO.

A stick welder is useless for car body repairs Stewarty, you need to get a MIG which uses gas too, not a gas-less MIG.

The problems regarding welding on your drive is the risk of a passer by getting a welding "flash". You need to put screens around your work to prevent this from happening. Also the local Fire Brigade may also have an opinion on this too.

Very true, you don't have to be that close to the welder to get 'flash' - Years ago I worked in a large factory and got it from someone who was arc welding well over 10 yards away from where I was working - very painful for a couple of days. You should also always use a mask as well - one of the guys was tac welding with an arc welder and instead of using his mask was just closing his eyes - he got some spatter that landed on his eyelid and burnt right through it, damaging his eye permanently - you can't afford to do that very often!
