Welding - richard1985
I have a 1973 austin minivan which i am restoring. I need a good mig welder to the body panels on the car but anything i have tried so far has either been too powerful or not powerful enough with the settings. I do not wish to spend enourmous amounts of money. Could anyone give any advice on a suitable welder. it would be much appreciated.

The welder I have and which usually comes out well in magazine tests is the SIP Migmate 130 turbo. Buy a copy of Practical Classics magazine and there are several companies that sell it mail order, I think Halfords and B&Q also sell it but I am not sure how good their prices are. This will do body panels and light chassey repairs no problem...

I too use the SIP unit but, I hire it from a local tool distributor. I don't have that much use for a welder, hence hiring is useful but, when my Daughter's vehicle needs an MOT, there is usually a bit of rust to attend to. I find the SIP extremely easy to use and, the range of adjustment allows for very delicate work and,also, within it's limits, some fairly robust welds

Hi John - I just asked someone else this question but thought I'd better ask you too.. Here it is

Hi - Just reading your message - I have a Cosmo 130 (B&Q) and believe it's the same welder... I'm just practicing with it but struggling with the arrangement of the 3 switches on the front - to get the best combination for car panels....

May I ask you what your typical settings are for thin steel - bodywork patches etc.. and what gauge metal you buy to weld in???

I could then use this as a starting point - I think I'm chucking too much wire at it at the moment and also not getting penetration

If there is any help you can give to get me started I would appreciate it... wire speed settings too etc... then I'll go off and practice some more

Many thanks


Tony

thankyou very much Ian, it looks like i'm gonna go with a SIP welder as some other people have recommended it aswell. Hopefully i'll have as much luck with it as you have. Do you restore cars much?
thanks anyway

I restored a Triumph Vitesse convertible and have done numerous welding on minis, a Lotus Europa (the metal parts as opposed to the glassfibre body!) as well as MOT repairs for friends that get to hear you have a welder.

In terms of gas for the welder, I got hold of a pub CO2 bottle from my friendly landlord and bought a regulator and this works well especially as my local welding supplies shop refills the bottle with CO2 for £10. This works out cheaper than buying the tiddly bottles that soon run out, however the arc runs cooler with CO2 than with Argoshield gas so effectively you lose a bit of power, but this would only be a problem with heavy welding (ie chassis repairs). If you are going to use the welder a lot you can hire a big bottle of Argoshield, however this would work out as expensive over a long period.

Good luck with it!

Hi richard1985,
interested to hear exactly what "austin minivan" do you have? A J4, by chance?

May I ask for pros and cons from real users of gas and gasless home mig welders. Infrequent light use is my intended use.

Use a gas one if you're in an area protected from wind and draughts;if you aren't get gasless(cored wire).There are some that can be changed over but you have the switch the welder from +ve. earth to -ve. earth (or vice versa).Having said that ,I've run my gas mig with cored wire and it seemed to weld ok;car passed it's MOT.

what van? - CMark {P}
Hi richard,
got it. You're right, the "mini" car is well known. ;-)

It is not a J4 then. The J4 was the forerunner to the Sherpa and a horrible, horrible thing. My brother and I shared a 1973 one, so we know. Even then (late 80s) they were as rare as hen's teeth having all been quite rightly crushed in the scrapper.

Good article in Car Mechanics May 2001 re Mig Welders. Best buy was SIP Migmate 130 at £169. Warning regards stiff trigger.
Car Mechanics February 2002 about budget welding inverters for TIG welding. Best buy Weldability Tecnica 1000 or Ferm Technica 1000 also from Screwfix Big stuff. Need TIG torch.

When I restored an old Midget about 15 years ago I bought a Clarke 100 basic MIG welder, one off the bottom of the range. Once I got used to it, it was absolutely fine on any gauge metal up to about 1/8" and it did a lot of welding. I think the key is practice.

I agree with PB. And I also have a Clark gasless and find it OK ish - I guess a SIP would be better. 100 amps with a good earth clamp is a hell of a lot of heat for car/van welding. The key to gasless is finding the wire make that suits you. It dear about £30/reel. But what you need is practice and protection - and a stiff trigger is a real bummer, when you will be likely to need quick control to do manual pulsed welding on really thin stuff.
Good luck
PS mig drip scars for about 18 months.

Have you considered an oxy-acetylene kit? Not only can it weld, but you can also braze, cut and heat. I find them more versatile than a MIG set. Wide range of heat with different nozzles etc

try a tig welder, a bit more expensive but a much better result i found, you could hire one.

Back in The Yook on a winter vacation visit and noticed they had flux-core wire welders in LIDL for 80 quid.

Dunno if they are any good, but I've mostly been fairly impressed with LIDL stuff for the price.

I'd guess this kit doesn't have the option of conversion to gas, though I havn't confirmed this.

Also "automatic" welding helmets for about 20 quid, which seems remarkably cheap.

Never used one of them but I'd think it would be very useful, since otherwise you can't really see what you are doing until you start the arc.

The automatic helmet does sound a good buy at that price as they do make the initial part of welding much easier. Not so sure on the welder as I’ve heard they’re nothing like as good as a gas mig.

Was actually 23 quid (actually actually the 22.99 jive) but still remarkably cheap.

I've only used oxy-acetylene on a car, though I did an evening course using gas mig on thicker steel and aluminium, which seemed to work quite well.

OTOH the last MOT welding I had done before I left the UK they were using a small flux-core (Clark I think), so they thought it did good enough welds to get the punter to pay for.
