•
Based on 3% drop and max. 7% below nominal at input power
connection during weld
The same guideline applies to power drops from the input power high
current buss to disconnect boxes for machine connection. Even though
slow-blow fuse size may be smaller than nominal for the cable size, the
high peak currents of stud welding necessitate appropriate cables. This
table is based on a 1500 Amp output.
