What is the duty cycle of the XMT 350 CC/CV, and what happens if I exceed it?

The duty cycle is 60%, meaning the unit can weld at rated load for 6 minutes out of every 10-minute period. Exceeding the duty cycle can damage the unit and voids the warranty. If overheated, a 'HELP' message appears and the unit stops producing output until it cools. (Page 11)
