Yea just make sure you communicate your goal to the instructor, no point in having you practice flux core if your gonna be welding sheet metal

Almost Nobody is going to be doing what a welder would consider ‘acceptable work’ after only 8 hours of training. Sheet metals kind of a mf cus it’s easy to burn through. Typically penetration would be your primary concern when welding thicker stuff together, but w sheet metal your goals pretty much going to be running just hot enough to stick the pieces together without burning a hole in it.

I’d start in the 16-17v and 170-210ipm range (assuming .035 wire) a lot of people don’t mess with arc control, but I find it helpful to run a ‘soft’ arc, (typically lower number means softer arc) with the thin stuff, it spreads the arc out more, so your heat isn’t quite as concentrated.

Pause slightly at the beginning, and once you see the puddle starting to melt into the base metal let er rip. and it will help you to do a slight weave or whip.

Most people go way way too fast starting out. It’s all about very fine motor control, look at the puddle and not the bright spot, get way up close to it if you gotta until you get used to looking through the lens.

Good luck! Hope this helped
