You've seen the sheer crap I've produced and you still say you think I could make do with what I have for body panels ! Thanks for that.
I'm very interested in the oxy thing. Maybe that's the way to go.
Have people seen this: Mig Welding Technique for Thin
Metal
Or, even better, this: http://www.mig-welding.co.uk/gasless-mig.htm
I ran across the site more than a year ago (things, projects, move very slowly with me) and it is the main reason why I have thought I'm on the right track with 0.8 wire and Mig and 1mm steel.
My mate got a reply for me from Cig welding about their 0.8 wire. Well, not them but some other outfit is who it turns out to be. They weren't too clear but they certainly didn't say 'no go' and blathered on about it being used for fixing cars, etc... We've written back and asked for some specific and definitive.... Hard ask, really, can't expect them to say it is rubbish and their lawyers wouldn't let them say it definitely can do this or that if it can't...
Worried me about zinc fumes. I googled it a bit and it seems like deadly poison to some folks and not to others. I've had no trouble at all as yet. None. I keep out of the plume, weld in an airy place (big shed, near the door) and don't do much. Don't wear a mask but I could. I will be careful.
Not sure about the story about preparing the sheet and then going for the chipping hammer - wouldn't you just lightly, carefully, grind it back?
You're right. I try to make do with what I've got and whatever common sense I can muster. And avoiding cost.
That might be a problem for oxy and even for gas mig if I finish up being convinced by someone that I have to go gas (though folks on this thread keep saying they did better with gasless - which supports those anecdotes I mentioned before about guys who claim to always use gasless because they weld in the open, etc... ) .
I'd have so little work for the gas that it'd be hard to justify the cost.
Anyway, we'll see. No one has convinced me of anything, yet....
I feel like I'm right back where I started... I could do it if I could find the trick...
and the biggest hassle between me and the trick is....
I can't see the bloody join !
So while I'm waiting for more convincing clues and/or maybe something from the wire manufacturers I think I'll try that nail-on-the-shroud thing...
p.s. Yep, very funny about the images. I can see those I posted alright. I'll try looking at them after logging out...
p.p.s. Yep. Worked like a charm, no problem at all. Get logged out and I see your thumbnails in the text, which I don't see otherwise, and clicking them gives me a big original. Great. Thanks.Last edited by abrogard; 16th March 2010 at 11:10 PM. Reason: additions.

abrogard,
Ignore those Cig welding salespeople.
As BenM78 said, 0.6 wire with gas for the body panels. That's the most conventional solution. Can your welder run with gas?
Different tools for different jobs. That applies for the helmet as well.
A bad helmet is good enough for some rough work. Delicate stuff needs better helmets.
As for your fluxcore link : Gasless MIG Welding
I don't see anything about wire thickness or material thickness.
The thin-metal link, he used gas.
For your previous post with your fluxcore welds. They aren't looking so hot but you already know that. You could bolt the metal together because it would have more strength. A couple of joining plates etc. Welding isn't always the best solution. (Especially if you're knocking holes through it via welding)

Well Dave got a phone call and an email from the fluxcore people. He's passed the email on to me. It has an attachment, a spec sheet for the wire.
The techie stated unequivocally that the wire was suitable for such welding and was capable of doing the job. However, the job wouldn't look so pretty. Until it was cleaned up. That's the nature of fluxcore and gal welding.
But a good, "proper" weld, yes.
I've attached the .pdf file that is the spec sheet.
The techie refuted the contention that the technology was basically wrong, not valid in such a wire size.
So that convinces me.
I can continue trying to weld this material with this wire. If I can find a way to see the job. Maybe a diopter lens and a nail fastened to the shroud and well chalked joint.
But no one - including that techie - is saying that it is easy. By its very nature there'll be spatter and a sloppy looking weld and even the wire seems to move around on its own.
So I might be better off dodging the whole thing and getting gas and 0.6mm wire. Or using oxy.
But first, considering all of this is about my desire to teach myself to be able to weld up car panels, I'd better get some practice on car panel non-galvanised material and see how that goes. What sort of material is that? What sort of typical thickness? Thinner than 1mm I think? What sort of steel? Someone told me car panels are made of special strong steel. But do we weld in ordinary mild steel or we have to get 'car steel' to weld in?
Maybe all those questions belong in another thread.
This thread was about seeing.
It got sidetracked into the validity of the job.
I think both of those questions are just about properly answered now.
1. There's various aids to seeing been mentioned. I've just got to try them all.
2. The job is valid but no one says it is easy.
And thanks very, very much to everyone who has helped by contributing to the thread.
regards,

Well if it's in the CIG pocket guide, it must be true.
"Smooth stable arcing and excellent fillet shape
and edge wetting are achieved when welding
galvanised steel fixtures."
They suggest it will work for 1mm.
I guess there's no harm still trying since you've already got the 0.8 wire!

Hi...
they 'suggest' alright:
"When ‘tuned in’ to the optimum current and voltage settings the wide range of wire sizes (0.8mm and 0.9mm) can easily be used in all welding positions, including vertical-up/down and overhead, on materials as thin as 1.0mm."
And 'trying' is what I'm doing all the time........ poor deluded fool that I am..
