Cooler activation
− ON= The cooler is always running when the power source is switched on. This mode is preferable for heavy duty and automatic welding
procedures.
− OFF= The cooler is always disabled because an air-cooled torch is in use.
− AUT= When the unit is switched on the cooler is switched on for 16 s. During welding procedures the cooler runs constantly. When welding is
terminated the cooler continues to run for 90 s + a number of seconds equivalent to the average current value shown using the HOLD
function.
Current HF
This parameter establishes the current value during HF discharge. The value of this parameter can be set as an absolute value or in SYN.
With SYN setting the HF current value is calculated automatically on the basis of the preset welding current value.
Consequences of a higher value:
− Arc striking is facilitated, even on very dirty workpieces.
− Risk of piercing excessively thin gauge workpieces.
Pilot arc
The function enables the output of a low current between the 1st and 2nd times of the torch trigger to shield the mask in advance and avoid the
risk of blinding flashback caused by the welding current.
