put positive and negative leads on backwards on my suitcase and welded for a bit will this effect my welder negatively?
---------------------------------------------------
shouldnt hurt anything. welding power sources are designed to be used on electrode positive as well as electrode negative.
swapping the leads is the normal way to change polarity on a lot of mig welding machines.
flux core wires typically...not always ..use electrode negative..
while bare wire mig uses electrode positive.
