Beginner welds

[1984clg]

Don't seem to be getting much penetration on 2mm thick plate just wondering if anyone had any suggestions. Thanks

For a 'beginner' as you call yourself, I would say there are some very good welds and close to penetrating through, in my opinion they would hold anything you welded, there is one or two that is sitting on the top, was that a different setting?

They were lower settings, I've only had a couple hours practice using thin steel(holes galore) but after reading a few posts decided to get some thicker steel much easier to practice on. Thanks for the reply! Is it normal for all the brown around the weld ? There's quite a bit.

The brown usually means a lack of gas coverage or low torch angle.

The gas dial says 10 lpm. The angle I've been using is just off vertical. Cheers for the reply

The brown around the welds is oxides from the weld pool, it will brush off.

If it is sooty deposit then it's usually a sign of lack of sheilding gas, 10lpm is about the norm if your regulator is accurate, I had the same and found any setting less than 12 caused it

I'll try turning it up a little see what happens.
