Hi guys,
I built a battery spot welder out of a microwave transformer by just replacing the secondary coil with 6 AWG wire wrapped 3.5 times. I am measuring 5 volts on my multimeter (not under load, not during a weld). But when I try to weld some thin nickel strip it burns a hole right through and throws red sparks everywhere. I have tried adjusting the number of wraps on the new secondardy coil but still not getting a good weld. Is this issue too much voltage or too much current? And do I need to adjust the gage of the wire?
Extra note. my electrodes are 12awg solid copper, should this be adjusted?
Any insight would be great,
thanks.
