Junglie Posted June 6 Share Posted June 6 Hi, It'll come as no surprise I'm sure that my early 110 needs some welding. Specifically engine mounts (V8 going in), an outrigger and rear crossmember plus the usual door frames. I have been loaned a gasless MIG by a kind neighbour and just did the engine mounts...but I don't think the weld is deep enough (or I'm far more carp at welding than I thought) as if I use the engine hoist I can very easily snap the welds again. It's a 45A unit. I suspect it's not man enough - would I be right? I also have access to a 100A (I believe) stick welder. Would I be better using that, getting a more beefy MIG or learning to weld better? Any advice/comment welcome. Thanks. Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted June 6 Share Posted June 6 45A won't be enough, For engine mounts 100A stick welder *may* do it, you can try it and see what happens, but stick is not as initially easy as MIG. Is anyone close to you that could pop in advise? Quote Link to comment Share on other sites More sharing options...

Is anyone close to you that could pop in advise? Sadly not. I can pick up a 120A Gasless MIG tomorrow - it's adjustable down to 50A so will probably do for all my needs i guess. I have welded before (stick and gas) but it was about 45 years ago doing 'O' level metalwork (I passed). Reckon that's going to suffice?

Bowie69 Posted June 6 Share Posted June 6 Probably! Chamfer the edge of the parts so you get a good deep pass in and should be fine. 1 Quote Link to comment Share on other sites More sharing options...
ianmayco68 Posted June 6 Share Posted June 6 Make sure you clean the area your welding the mount too , shiny steel is best . If you’ve got some scrap lying around clean that up and have a practice on that first till you feel comfortable and 0.8 mm wire would be best . Once happy you could multi run it , putting a run of weld on top of another the link shows a pic https://images.app.goo.gl/axeed9BA9ajxnKZq8 . 1 Quote Link to comment Share on other sites More sharing options...
Stellaghost Posted June 6 Share Posted June 6 100amp stick with 2.5 rods should burn in nicely however you will need to practice vertical welding unless you can stand the chassis on its side Go on can however purchase multi- positional rods and weld downwards I find gasless mig horrible but that's just me Which ever say you go practice on scrap is essential Regards Stephen 1 1 Quote Link to comment Share on other sites More sharing options...

steve b Posted June 6 Share Posted June 6 Gasless MIG needs to be positive earth to stand any chance of working. Practice parts at the same position the repair will be worthwhile (after mastering it flat) as said above Steve 1 Quote Link to comment Share on other sites More sharing options...
Junglie Posted June 6 Author Share Posted June 6 Thanks guys. As always this forum never disappoints. I've got plenty of scrap lying around to practice on, fortunately. And the unit I'm looking at comes with .5kg of 0.8mm wire, which is a happy coincidence... Quote Link to comment Share on other sites More sharing options...
bushwhacker Posted June 7 Share Posted June 7 If you have a few areas to weld up it might be worth a look at second hand or even new. 150amp but better with 200amp gas. 1 1 Quote Link to comment Share on other sites More sharing options...

Yes, I've been offered a 150A gas/gasless/MMA on long term loan so I'll run with that. I don't have the facilities to work indoors so gasless is more convenient, obviously. Then I can use my spare time (ha!) to refresh myself on other techniques and be useful to locals needing welding. Quote Link to comment Share on other sites More sharing options...
landroversforever Posted June 7 Share Posted June 7 Unless its blowing a gale, that kind of welding with gas isn't going to be an issue outside. 1 Quote Link to comment Share on other sites More sharing options...

Given I almost always end up welding outside with MIG, I'd disagree with this, if there's much more than a gentle breeze you need to be careful with what you are doing or the gas shield just blows away, and you end up with porosity. You can. Strategically place stuff around the weld (even you other gloved hand) which can help. 1 Quote Link to comment Share on other sites More sharing options...

Outside corners are another thing, but internal corners like the sides of an engine mount have never given me any issues. Quote Link to comment Share on other sites More sharing options...
