9.1 Parameter settings for MMA welding
Select the STICK method using button (
3
). Current is adjusted with knob (
4
). Welding current is
limited to 160 A. The VRD (Voltage Reduction Device) function is activated with the button (
6
),
which increases the safety of the welder especially when welding in places with an increased
risk of electric shock. The VRD function reduces the idle mode voltage from the level of
60 V to 12 V. The active VRD function makes it difficult to ignite the arc, however, therefore user
needs to scratch the electrode several times. No other welding functions are available.
