the exceptions are described as below.
Voltage type parameters
Voltage type parameters include initial voltage, peak voltage and crater voltage, and they are used for
adjusting the arc length. When voltage is high, arc length will be long, and when voltage is low, arc length
will be short.
Arc characteristic
It is located at
“
peak segment-current column-arc characteristic (-/+)
”
. Besides the function described
in standard MIG/MAG welding, fine adjustment of arc length can be achieved through this parameter.
Parameters in double pulse MIG/MAG
There are 21 adjustable parameters in double pulsed MIG/MAG welding, namely pre-flow time, initial
current, initial speed, initial voltage, upslope time, LF peak current, LF peak speed, LF peak voltage,
thickness of base metal, arc characteristic, LF pulse duration ratio, LF frequency, LF base current, LF base
speed, LF base voltage, spot welding time, downslope time, crater current, crater speed, crater voltage
and post-flow time. 11 parameters of them, namely LF peak current, LF peak speed, LF peak voltage,
thickness of base metal, arc characteristic, LF pulse duration ratio, LF frequency, 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.
ø Operation tips Arc ignition in pulsed MIG/MAG
It is very important to set the arc ignition parameters in pulsed MIG/MAG, especially for welding
aluminum. The initial parameters (initial current and initial voltage) and upslope parameter (upslope
time) available for the machine should be set properly, for they affect the arc ignition performance to a
great extent. When welding aluminum, users may select higher initial current and initial voltage
generally.
