Duty Cycle:
At full output: 0.5 seconds “ON” – 20 seconds “OFF”
The equipment can be fused based on less than the maximum amperage draw due to the duty
cycle. Refer to NEC Code Section 630.31 Ampacity of Supply Conductors and Table 630.31
(A) (2) Duty Cycle Multiplication Factors for Resistance Welders (NPFA National Electric Code
2011). Some areas refer to 2 phase instead of 1 phase. The incoming power goes directly to
an isolation transformer so the unit will operate identically on 1 or 2 phase power.
Note: To obtain full rated output the following conditions must be met:
1. No more than 30’ of 1000 MCM cable double 30’ 4/0 cables attached to each of the Output
Lugs on the front of the unit. If Output 2 and/or 3 are not used — No need to hookup ca-
bles to that output.
2. A power source of the proper voltage, frequency and phase (as designated on the
Mag-
naflux Data Plate
) capable of providing current per the nameplate for the power pack. It is
highly recommended that an electrical fused disconnect be installed either on the wall be-
hind the unit or on a pedestal near the unit.
