You just need to get a water cooled torch and you will manage that no problem, well as long as it has a leakHaha
I’m almost there!

Keep practicing and one day you will be able to lay as nice a weld as I can]
Tbh under the circumstances it’s pretty good. I’ve seen worse achievements on non leaky set ups.

Well considering I couldn’t tack anything except in error I managed this earlier. (Excuse the first inch where I was getting a feel for it!)
I did manage to fill the 6mm hole you can see near the top too!
Manage this run last night but fusing 2 pieces together looks nothing like this!

Never turn that off mate. You’ll badly contaminate both the electrode and the job.
Down slope should have something on it too maybe a second to give you time to move the arc away from the tack before complete solidification. You get a crater on your tack it will almost always split. Check out my settings again.

I personally can’t do it with the slope down off. I end up with a good 50% of them cratered and 50% of them end up cracked. It’s not to say it can’t be done but my personal preference to get 100% spot on is to use a bit of slope on release.

Get yourself a welding table of a sheet of steel, so you can get sat down, its far easier then being stood at the vice.

I see lots of rookies here.
First one don’t scrub the plates
Just take your time and clean them up with solvent. It’s a common misconception that people think they need to rip off the aluminium’s oxide layer and you really don’t. Let the process take care of that. I would never go anywhere near a customer’s product I was making with a wire brush.
Second your adding filler too soon before the pool has developed. I can see massive amounts of black nasty speckles particularly at the start where your filler has melted across the arc and blobbed on the metal dragging in alsorts of nastys. Get that pool well fluid before adding and make sure you hit the pool. Keep that arc tight.
your material isn’t helping. It’s pretty nasty stuff with all that black crud on it. It’s not even good enough to practice on. You can’t fix that with a wire brush. Get some nice clean sheet that still has the plastic on. Peel and weld.
once welded leave welded. You can’t smooth it over with the arc that’s just gonna over heat the joint and give you false impressions of what you can and can’t do. Aim to get it on the first hit because again you can’t run over a customers part incase you push the metallurgy to crack.
Hi,
An interesting thread and I too am still learning. My box of practice pieces was filling up nicely until I stopped creating soot and puddle dipping. Stick with it you'll win in the end.
Kind regards, Colin.
Echoing Munkul's excellent advice to me; PRACTICE; PRACTICE; PRACTICE. I'm now not too bad on flat sheet but I'm finding curved surfaces a whole new load of fun.
