CUTMASTER 10MM, 12MM
SYSTEM INTRODUCTION 2-2 Manual 0-5197AD
2.05 Power Source Specifications
CutMaster 10mm Plant Part No. 1-4730-6
CUTMASTER 10mm Power Source Specifications
Input Power 240 VAC (+/-15%), 1 Phase, 50/60Hz
Output Current 20-30 Amps @ 240VAC
CUTMASTER 10mm Power Source Duty Cycle (Note 1)
Ambient Temperature 104° F (40° C)
Duty Cycle 40% @ 240VAC
Rated Current 30 Amps @ 240V
SL60 Torch Gas Requirements (See Section 2T.02)
Note
1. Duty Cycle is the percentage of time the system can be operated without overheating. Duty cycle is
reduced if primary input voltage (AC) is low or the DC voltage is higher than shown in this chart.
2. Air supply must be free of oil, moisture, and other contaminants. Excessive oil and moisture may cause
double-arcing, rapid tip wear, or even complete torch failure. Contaminants may cause poor cutting
performance and rapid electrode wear. Optional filters provide increased filtering capabilities.

NOTE
IEC Rating is determined as specified by the International Electro-Technical Commission. These specifica-
tions include calculating an output voltage based upon Power Source rated current. To facilitate comparison
between Power Sources, all manufacturers use this output voltage to determine duty cycle.
TDC Rating is determined using an output voltage representative of actual output voltage during cutting
with a TDC torch. This voltage may be more or less than IEC voltage, depending upon choice of torch,
consumables, and actual cutting operation.
