could occur if 4
6
0VAC or higher
is applied.
The following 400V Primary Current recommendations are required to obtain the
maximum welding current and duty cycle from this welding equipment:
WARNING
Exceeding the duty cycle ratings will cause the thermal overload protection circuit to
become energized and shut down the output until the unit has cooled to normal
operating temperature.
CAUTION
Continually exceeding the duty cycle ratings can cause damage to the welding power
source and will void the manufactures warranty .
NOTE
Due to variations that can occur in manufactured products, claimed performance,
voltages, ratings, all capacities, measurements, dimensions and weights quoted are
approximate only. Achievable capacities and ratings in use and operation will depend
upon correct installation, use, applications, maintenance and service.
