i want to make a roof rack with my 90A flux core welder. any tips and tricks i should know about? I've also been practicing on scrap metals and I am having a hard time welding thin sheet metals.
if you are still using the original wire that came with the HF 90amp then you will keep getting ugly welds till you change it. That wire that comes with it is worthless! Get some new wire and you will notice a huge improvement in splatter and bead quality.
thats some good welding! also thin metal do a start stop teqnique. it works for me keeps the heat from building up. also thin its good to lower voltage and up the wire speed
