Hi, I have a somewhat cheap spotwelder that uses a lipo battery thats 3s2p 15Ah 100c so 1500A, and I have a major issue with heat. The cables get hot allready at 4-6 welds. The spotwelder is plugged in with the 10awg negative from battery + a 22awg that splits from the 10awg positive. The negative electrode/probe wire comes out of the welder while the positive goes straight out from the battery. <--[W]--(B)--> / (Probes <--/-->) (Welder [W]) (wire --) (Battery (B)). Is there a way for me too counteract this by lowering current too the welder or do I have too switch out the cables for thicker ones? I'd rather not change cables on the battery as I have never dealt with lipo before. Also just too see, is there a way too stop backcurrent from flowing back too the battery at this high current? Or can i parallel some superfaradcapasitors with the battery too help protect it?
Spotwelder help.
