3.4 Power supply input connection
The HST201 AC/DC PULSE PFC welding machine features electronic switching power
supply allowing it to be connected to any 115-240VAC, 1-Phase LINE power outlet.
208-240VAC LINE CONNECTION:
Machine is provided with NEMA 6-50P LINE Service
cord to be plugged into any 6-50R outlet with 208-240VAC, single-phase power and
50-amp
circuit breaker.
110-120VAC LINE CONNECTION:
Machine is provided with NEMA 6-50R to NEMA
5-
15P “Jumper” Service cord. This allows machine to be plugged into any 5-15R standard
outlet with 110-120VAC, single-phase power and
20-amp circuit breaker.
In the event NEMA6-50R or 5-15R outlets, with rated LINE circuit breaker
amperage are not available, they should be installed by a licensed electrician in
accordance to all national & local codes.
In the event LINE power supply is over voltage (>245) or under voltage (<195),
protection circuit inside the machine will illuminate alarm light and current will be cut off.
If the power supply voltage continually goes beyond the safe work voltage range, it will
shorten the life of the machine. If this occurs, the below measures should be taken:
Change the LINE power supply. Such as, connect the welder to a dedicated circuit.
Shut off other machines using LINE power supply at the same time as welding.
WARNING: Any modification or removal of factory installed service power cords
will VOID MACHINE WARRANTY!
