first time I’ve picked up a torch in around four or five weeks, can’t remember exactly, due to being away with work. Seeing as I’ve got two weeks off I decided I’d knock a fire pit up for the summer. All was going well until I had an issue. The steel started to fizz and spit and I ended up with some hideous holes in the weld bead.
I’d cleaned everything up with acetone after I’d cleaned the metal with an abrasive flap disc and even used a stainless wire brush. All filler was cleaned down as well as the stuff I have is honking straight from the pack.
Now as I’m a novice I can’t begin to figure why this happens so hopefully someone here will have the answer. If it’s down to me then I want to know so I can square it away as it ruins what was quite a nice run.
This was an outside corner on 3mm cold rolled sheet, 80 amps. The pops happened before I even got filler into the puddle so doubt that’s the cause. Any ideas peeps?
And lastly some of the other runs. I did a bit on pulse, .7 frequency, 100 amps, 33% on time, 33% background current. Quite liked this as it gave me a nice little rhythm to settle into.
Cheers
Tom
