I'm not talking ship just being a friend. Get some leather gloves the gloves you are wearing will melt the instant molten metal heads them. Nice welding gloves are relatively cheap, you can get a set at harbour freight for 15-20 bucks.
U should get shielding gas for ur welder ur welds will turn out better as well as prep ur surfaces clean the paint off to metal for better results also maybe turn ur voltage down some on thinner material but it’s great u are trying to learn something new stay at it practice makes perfect
My turbo B20 Integra after 2 years of abuse decided I’d go for a little more power, took it up from 11 to 13 psi, log never shows it leaning out but blew cylinder 3. Probably should at least do the ring gap if anything if your planning for more than 300hp.
