** When using liquid cooled torches in freezing conditions, use an adequate cooling liquid.
Duty cycle
The duty cycle refers to the time as a percentage of a ten-minute period that you can weld at
a certain load without overloading. The duty cycle is valid for 40 °C / 104 °F, or below.

Liquid cooled torches
Return temperatures of more than 60 °C can shorten the lifetime of the torch or cause
damage or destruction of the torch. The cooler must always be filled with sufficient cooling
liquid, refer to the instruction manual for the cooling unit. In case of a high thermal load on
the torch, use a cooler with sufficient capacity. Use only special cooling fluid containing
