How bad is Gasless welding?

[DrSebWilkes]

I've found a really cheap gasless MIG welder and part of me wants to buy it but I'm sure the results will be awful.

Don't waste your money. They're awfull, you will be curse word into the wind with one of those.


A good quality secondhand mig welder will be the cheapest way of getting a good machine. Just make sure it's all working and looks to have been looked after as they can be costly to repair. Look at rental free gas bottles or the volkszone box gas offer. Or on gumtree for a rouge gas bottle.

R tech welders appear to be well regarded for affordable new machines.

You get what you pay for with welders, you want the best you can afford really. Quality makes a big difference. I paid quite a good price for mine secondhand, it was £700 but cost £3k when new.

Do your home work and you will get a bargain.

What I feared ... okay dokey thanks.

Also gasless has been linked to cancer, due to the fumes given off from the wire.

Is that worth my money?

[bluemax]

i wouldnt personally, it would be a false economy.

i would be looking at a good quality work horse, something like this, www.ebay.co.uk/itm/Murex-Tradesmig-160-240-v-mig-welder-single-phase-trades-mig-esab-/301973695111?hash=item464f08ea87:g:x70AAOSwAahXPODp it may end at the same sort of price as that new one and be ideal for the job plus give you hassle free service.

and remember to budget for gas, as you will need it.


you might find a clarke mig for sale quite cheap locally to you, they're not great but theres a lot around and would be good to learn on.

Wolf stuff is usually the same kit as Clarke just wearing a different badge. I bought a Clarke mig off here for £40 and run it using pub gas - not the neatest of jobs but it's kept my daily hack on the road no problem.

It depends what kind of work you want to be doing and how neat a job you want. I'm no great welder so the cheap Clarke one is fine for my needs.

You pays your money and you takes your choice.

[DrSebWilkes]

Fair enough. I just don't want to do any bodge jobs on the Jag - it doesn't seem right. Of course, half of it is the operator, but I'd like to not limit myself too much before I even turn on the plug.

near all my welding has to be done outside, gasless works well for me. mate cant use it worth a damn. get a gas no gas. best of both worlds. anyway welding takes patience, so do not give up.

[composimmonite]

Before you go anywhere near your car please sign up for a college / night school welding course. If you are still at school / college / in education then I THINK such night school courses might be free. Better to be taught how to weld properly rather than teaching yourself. I cringe every time I read about peoples work and they say "it might not be pretty but is strong" when they have no idea what they have done is absolute rubbish.
I spent a year at night school in 1981 to gain an industrial welding certificate and worth every minute of the course.

i have a lincoln 200 it a good machine but i got it at a great deal through work
stay away from gas less if you can you can surely get a small bottle of mixed gas
a just practice on a bit of scrap it will help you get the settings that your most
comfortable with

[DrSebWilkes]

My DT teacher is going to privately teach me to do it anyway ... thanks for the tips.

[awoo]

I would echo what compo said, I did the same and it was totally worth getting shown what to do by a pro.

Welding is very much a skill that takes practice to do it to a standard, like playing piano or drawing etc


Welding tips and tricks on YouTube would be worth checking out

[gazz81]

I have both gas and gasless welders and other than the fact the gasless has a slightly dirtier weld than the gas one it still performs very well.
It would be easier to learn on gas and go back to gasless, but probably harder the other way round.

[dodgerover]

I've only used gas less once and that was outside on maybe 6mm plate, to be fair it made a decent enough job. I would have been prettier with gas though.

[g40jon]

As others have said, if you want the option to weld gas-less, buy a gas/no gas model, then you can run either, thus giving you the best of both worlds. Gas-less has its uses. I've welded stuff up on a windy winter day, where a gas mig would not have worked. It is fairly good on thick steel, but on thin steel like bodywork it can be much trickier to get good weld penetration. You either end up blowing holes in the metal, or leaving messy metal blobs all over the panel! Gas-less also works much better with clean steel than it does with rusty, thin metal.

[DrSebWilkes]

Yeah everything I've read tells me to not go for a purely gasless MIG. Thanks guys

I know nothing about welding but I've seen quite a few items in the press over the years about people's cars, (classics or otherwise), going up in flames during welding work.

Given that you'll presumably be doing work from a position of novice you'd just need to be alert to the potential for this.

Things that you can do to mitigate for such incidents:-
Ensure that you have a variety of appropriate fire extinguishers readily to hand whenever you're welding or doing any other similarly risky work.
Make sure that your fuel system is not compromised at any point; e.g. dribbles from a perforated fuel line could be all that it takes to get a hold.
If you're working in the immediate vicinity of elements of the fuel system it will possibly be worth you emptying the car of fuel and temporarily removing components such as tank(s) or fuel lines. Petrol vapour is more combustible than enclosed petrol.
Carpets, headlining material & the insulation on the wiring loom are other things which can catch alight if you don't take enough care, move / remove / cover as needed. 

Sorry to sound like the Prophet of Doom but it's better to be prepared than to be mournful.

[DrSebWilkes]

Thank you Mkx, my forum star!

For protecting the headlining, will just a flame retardant cover do? (Saves taking the whole thing out)
