3. GENERAL NOTICE OF OPERATION
3.1 Rated duty cycle
CAUTION
Use at the rated duty cycle or under. If exceeding the rated duty cycle, the welding machine
may be damaged.
•
TURBO PULSE 350 (CPDP-350) Rated duty cycle is 60% at 350 A.
TURBO PULSE 500 (CPDP-500) Rated duty cycle is 100% at 500 A for CO
2
, MAG, & MIG;
60 % at 500 A for Pulsed MAG, & Pulsed MIG
•
The duty cycle is the percentage of a ten-minute period that the welding power source can be
operated at the rated output without causing overheating and damaging the welding power
source. This welding power source can be operated for six consecutive minutes, but it must
rest at no load for the remaining four minutes to allow for proper cooling.
ON OFF
6 min. 4 min.
10 min.
•
If exceeding the rated duty cycle, temperature rise of the welding power source and torch can
exceed the allowable limit, and will damage the equipment.
•
The following figure indicates the combination of welding current and duty cycle.
Observe the duty cycle in accordance with welding current.
•
The duty cycle is affected by other equipment such as the welding torch, etc.
Therefore, observe the lowest rated duty cycle of combined products.
