Arc breaking voltage (U1)
It is located at
“
peak segment-voltage column-voltage (V)
”
, and it is used for setting the arc breaking
voltage during welding. This parameter is specially designed to meet the requirement in HF intermittent
welding, and its resolution is 0.1V. The arc breaking voltage indicates the maximum allowable arc voltage
during welding, that is to say, welding can be continued 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-flow time, initial current,
initial speed, initial voltage, upslope time, peak current, peak speed, peak voltage, thickness of base
metal, arc characteristic, spot welding time, downslope time, crater current, crater speed, crater voltage
and post-flow time. 9 of these parameters, namely peak current, peak speed, peak voltage, thickness of
base metal, arc characteristic, spot welding time, 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 operation mode
before any operation on parameters.
1 Pre-flow time
It is located at
“
pre segment-voltage column-time (s)
”
, and users can set it according to their own
technical requirements.
2 Initial current
It is located at
“
initial segment-current column-current (A)
”
, and it varies with the change of the initial
speed. Therefore, it is unnecessary to set this parameter when the initial speed is set properly.
ø Operation tips
Arc ignition mode in MMA (arc force
≠
0)
Low current arc ignition: It can be also called lift/soft arc ignition. Set the arc ignition time to be a
value other than 0, and the arc ignition current (I1) to be a value lower than I2 and the machine
will enter into low current arc ignition mode. Touch the work piece with the electrode, and lift the
electrode to the normal position to weld after arc is ignited.
High current arc ignition: It can be also called contact/hot start arc ignition. Set the arc ignition time to
be a value other than 0, and the arc ignition current (I1) to be a value not lower than I2 and the
machine will enter into high current arc ignition mode. Touch the work piece with the electrode,
and normal welding can be carried out without lifting the electrode.
