1.4

DUTY CYCLE AND OVERHEATING

The duty cycle is the percentage of a 10 minute period for which
the welder can continue to weld without overheating. If the ma-
chine overheats, the welding current is shut off and the relative in-
dicator lamp illuminates. In this case, leave the machine to cool for
approx. 15 minutes and, before restarting, lower the welding cur-
rent value and relative voltage or reduce the work time.
Example: 400 A - 60% means working for 6 minutes at 400 A with
4 minutes rest time.

VOLT - AMPERE CURVES

The volt-ampere curves show the welder's maximum output cur-
rents and voltage (see page XVI - XVII).
