NOTES

The table above is based on the following output current and voltage:  130vdc @ 60A

An energy limiting fuse UL Class RK-1 (examples:  BUSS LPS/LPN-RK or Gould-Shawmut AZK-A6K) should be
used to minimize damage to Plasma Cutting, Welding or power distribution equipment.

NEVER

 use replaceable element fuses like UL Class H, or "one-time" fuses like UL Class K5.

Primary input power cable must have an outside diameter of 0.69 inches  / 17.5 mm or greater.
