Greetings All,
I have a handheld spot welder, the type used for autobody sheet metal
among other things. I am converting it to a stationary spot welder and
one thing that would be nice is to be able to limit the current for
thinner material. The input voltage is 220 volts @ 15 amps. Can I just
use an appropriately rated power resistor on the input side to reduce
the current? The welding current is 4000 amps and the suggested weld
times are specified in pulses at a pulse rate of 60 Hz. For example
the suggested weld time for .010" mild steel is 4 pulses. This is an
awfully short time period and I would like to make it a little longer
so that the timing periods allow more tolerance.
Thanks,
Eric
