just out of curiosity... when you say "wire brush all your connections" are you talking about where the flange/materials meet? Are you also talking about for stainless? Just curious... cause im a stainless sheetmetal working and ive never wire brushed stainless before welding....stainless as far as i know is not like aluminum and doesnt require brushing/cleaning before welding... assuming you dont get any dirt and greese where you are welding lol
