Arc breaking voltage (U1)
It is located at “peak segment-voltage column-voltage (V)”, and it is used for seng the arc breaking
voltage during welding. This parameter is specially designed to meet the requirement in HF intermient
welding, and its resoluon is 0.1V. The arc breaking voltage indicates the maximum allowable arc voltage
during welding, that is to say, welding can be connued when the arc voltage is lower than U1, or else
welding will stop immediately. Generally, the arc breaking voltage should be higher than 40.0V.
Parameters in standard MIG/MAG
There are 16 adjustable parameters in standard MIG/MAG welding, namely pre-ow me, inial current,
inial speed, inial voltage, upslope me, peak current, peak speed, peak voltage, thickness of base
metal, arc characterisc, spot welding me, downslope me, crater current, crater speed, crater voltage
and post-ow me. 9 of these parameters, namely peak current, peak speed, peak voltage, thickness of
base metal, arc characterisc, spot welding me, crater current, crater speed, crater voltage can be
operated either through the control panel on the power supply or through the control panel on the wire
feeder part, and other parameters can be operated only through the control panel on the power supply
part. Select the desired welding mode, base metal type, gas type, welding wire type and operaon mode
before any operaon on parameters.
1 Pre-ow me
It is located at “pre segment-voltage column-me (s)”, and users can set it according to their own
technical requirements.
2 Inial current
It is located at “inial segment-current column-current (A)”, and it varies with the change of the inial
speed. Therefore, it is unnecessary to set this parameter when the inial speed is set properly.

Arc ignion mode in MMA (arc force≠0)
Low current arc ignion: It can be also called li/so arc ignion. Set the arc ignion me to be a
value other than 0, and the arc ignion current (I1) to be a value lower than I2 and the machine
will enter into low current arc ignion mode. Touch the work piece with the electrode, and li the
electrode to the normal posion to weld aer arc is ignited.
High current arc ignion: It can be also called contact/hot start arc ignion. Set the arc ignion me to
be a value other than 0, and the arc ignion current (I1) to be a value not lower than I2 and the
machine will enter into high current arc ignion mode. Touch the work piece with the electrode,
and normal welding can be carried out without liing the electrode.
