6.3 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 parameters of them, 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 part 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. Besides, 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 “preposed 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.
3) Initial speed
It is located at “initial segment-current column-wire feed speed (m/min)”, and it varies with the
change of the initial current. Therefore, it is unnecessary to set this parameter when the initial
current is set properly.
4) Initial voltage
It is located at “initial segment-voltage column-voltage (V)”, and it varies with the change of the
initial current or initial speed. Beside, this parameter can be adjusted within a certain range.
5) Upslope time
It is located at “upslope segment-voltage column-time (s)”, and it makes sense only in programmed
4T mode.
6) Peak current
It is located at “peak segment-current column-current (A)”. Since peak current, peak speed and
thickness of base metal are interacting parameters, if one of them varies, the other two will be changed.
Generally, users may choose one of the three to operate according to their own technical requirements
or operation habits, leaving the other two parameters out of consideration.
7) Peak speed
It is located at “peak segment-current column-wire feed speed (m/min)”. For the relative description,
see the contents of peak current above for reference.
8) Thickness of base metal
It is located at “peak segment-current column-thickness of base metal (mm)”. For the relative
description, see the contents of peak current above for reference.
9) Peak voltage
It is located at “peak segment-voltage column-voltage (V)”, and it varies with the change of the
peak current and its interacting parameters. Beside, this parameter can be adjusted independently
within a certain range.
10) Arc characteristic
It is located at “peak segment-current column-arc characteristic (-/+)”, and the recommended value
of arc characteristic is 0. If the arc force is big, the arc will be hard and there will be excessive
spatter. If the arc force is small, the arc will be soft and there will be little spatter. This parameter
