* Ratio of actual working time to total working time.
Note 1: This ratio is between 0 and 1 and may be expressed as a percentage.
Note 2: For this document, the duration of a complete duty cycle is 10 min. For example, with a duty cycle of 60
%, the load time of continuous 6 min is followed by an idle time of 4 min.
The duty cycle was determined at 40° C by simulation.
List of equivalent models: None
TIG guide value for shielding gas volume:
Gas nozzle diameter [mm]² / 17 = Shielding gas volume [l/min]
The gas consumption can be calculated on the basis of the gas nozzle diameter.
