WARNING!
Exceeding duty cycle can damage power source or torch and void warranty.
Example:
If the power source operates at a 40% duty cycle, it will provide the rated
amperage for a maximum of 4 minutes out of every 10-minute period. The remaining time, 6
minutes, the power source must be allowed to cool down.
Figure 2. Example of 40 % duty cycle
A different combination of duty cycle and welding current can be selected. Use the graphs
below to determine the correct duty cycle for a given welding current.
