Default Re: Welding newbie need advice

Venice gives good advice. Trying to get good penetration when welding thin metals sometimes requires a stop-and-weld method. This means doing a short bead, stopping and then welding again. Practice on some scrap metal. Find some about the same thicknes of the project you're working on and give the weld-stop-weld method a try.
Running long or continous beads on thin material is hard and requires a lot of practice. The stop-and-go method will help.
Also on a MIG machine, the slower your wire feed speed, the hotter the weld. I don't know if your machine has an adjustable wire feed speed but try speeding it up for thinnner material.
