Welding our old tat using Gasless Mig

[Bobthebeard]

Is it just me being hopeless or is Gasless Mig like trying to weld using kiddies sparklers?

[Conrad D. Conelrad]

I'm a craptacular amateur MIGger but I've read a lot on the subject and seems gasless is a lot more difficult on thin metal.

[Bobthebeard]

Had spectacularly bad results using Gasless.... Ok! Am new to MIG welding but nothing ever stuck to anything!

Made a huge splattery mess also.... HO hum

[Mr_Bo11ox]

Everyone reckons gasless is about 50% harder than 'with-gas', but you should still be able to get a half-decent weld. Bosh up some pictures of your efforts and we'll give you some pointers.

Greetings Mr B! Feel honoured to have a reply by such a staunch Autoshiter by the way. As a lurker tis an honour.

Anyroadup, ground down the Gasless efforts and bought a proppa MIG welder to re do the job. Still not pretty, but by Jove it melted steel and stuck together!

Here is my efforts,with gas. Sort of erotic art I think.

[Bobthebeard]

My cap is truly doffed sir!

Well done! My efforts pale into insignificance

wire speed too fast judging by that picture

[Mr_Bo11ox]

yeah deffo, plus I would practice a bit on some clean/new steel before trying to weld an old exhaust manifold, they never weld very well

[Bobthebeard]

After much trauma and wasted hours I tend to agree, but welding is one of the skills that only the dedicated can learn with tears, blisters and many many visits to Halfrauds for things they can't afford and don't really need....

what model of welder is it?

[HillmanImp]

I was welding this summer and had a mare with the weather using gas. The wind was blowing the gas and I could not get a good weld at all. I imagine, in an outdoors (bad weather) situation gasless might be better?

It works better when the welders cranked up on thick metal as I think it's designed for welding tractors together in farm yards. It's also not as fussy about the metal being spotless like with gas either is but I found it a nightmare to use on thiner metal as you can't get a weld bead going with it. The weld just looks like lots of little dog shits.

While you're getting the hang of migging, try doing it as a lot of little tacks, stop / start, join them all up, then when it goes wrong there's only a small amount to grind off, and you can get away with the current a bit high, while you play with the wire speed until you find the settings that work best, and mind you clean the metal good enough to mott on.

I've had plenty of success with gasless, but it works better with thicker metal. I haven't tried it with bodywork, but I expect it would be very hard because that first arc strike is GR12 for blowing holes in things. It also makes a lot of mess, so have a good selection of wire brushes
