Thanks Allan. I am going to ask you a lot of questions over the next couple of months if you are up for it? Thanks

I just bought a Bossweld Treo welder and set it up yesterday for MIG. Its not the best brand but I must say that the performance is smooth. I tested it doing a little stitching and it performed very well.

Used a cutting wheel to put a 1mm gap in a piece of scrap and tried the stitch. I think I just need to up the gas rate a little, other than that I would be pleased with this on the hidden panels. What should my gas be set at for MIG? I have Argon\CO2 mix.

I run gas at 10 it's not unusual with a gap to go from side to side to fill the gap with weld if the power controll is 1 to 5 set it on 2 and wire on 2 if it spits. It's the wire speed move it back or forward until it sounds smooth with a crisp crack. It's real hard to explain it mate. I see nothing wrong with what you have done on that panel

Gas looks fine mate. In all honestly, if i were you I would set it as low as you can get it as it is bloody expensive and you really don't need it full bore anyway.

As for the gap, well, some may say differently, but I would butt the panels together instead if having a gap. If you are inexperienced then you will chuck more heat in than necessary chasing that gap and end up buckling your panels.

As I said, others may say different, but try butting the panels up and then weld, you will notice a difference.

Another trick I have learnt over the years when tacking thin sections is to lay the torch as flat as you can and run the wire over the top of it if you know what I mean......

This way the wire hits one edge and as it melts if catches the other edge and providing a flatter and more consistent tack area.

Ash is right In all honesty I myself set my gas till I can just hear it but I wanted to tell you what the experts say. But you can experiment. If you need a gap then ok but as Ash says when welding body steel together I also butt it up close together

Ok, so if I butt them together I just need to make sure that I get enough penertration through the joint. I have a couple of sheets of .95 Zinc coated so I will cut some small pieces and have a bit of a practice.

Please keep the info coming as I go. Been a long time (25 years) since I finished my engineering apprentceship. Only really Arc welded 4mm steel since then, apart from blowing the crap out of everything with a cheap chinese MIG.

Ash, do you mind me asking what area of Brisbane you are located in?

OH!! Didn't even realise you were a brissie boy.

I am northside, I live near Strathpine. What about you mate?

Btw, won't take much to get peno on .9 stuff man. Butt it togetherr and see how you go. Also, turn your gas down for economy.

West side, Anstead.

Did I see that you had a Camaro in one of the build threads?

Slowly getting there. Built a table top today to bash stuff against and mount my vice on. Used the new welder and gasless for this.

The welder is a Bossweld Treo that comes in at ~$1000. Jeez its great to use a quality tool instead of the old Chinese POS I used to have.

Still got a bit of practice for the light body stuff by the looks of it!!!

Got a bit done today. Jeez these old girls don't let their secrets up easily huh? Everything was well and truly stuck and needed lots of grunt to get them moving. Still gotta get the frame off but nearly at a point where it can be blasted to reveal more horrors! Used a good deal of WD40 on the frame bolts.

Pasenger footwell. I have a patch panel coming for this and the firewall extension
