What is the duty cycle of the Maxstar 161 STL when running at 160 amps on 240V?

At 160A on 240V, the duty cycle is 20% for both TIG and Stick modes. For TIG at 160A, the rated output is 16.4 VDC, and for Stick at 160A, the rated output is 26.4 VDC. Exceeding the duty cycle may trigger thermal overload protection to prevent machine damage. (Page 2)
