11 Downslope time
It is located at
“
downslope segment-voltage column-time (s)
”
. The craters can be filled by adjusting
this parameter properly in non programmed 4T mode.
12 Crater current
It is located at
“
crater segment-current column-current (A)
”
, and it varies with the change of the crater
speed. Therefore, it is unnecessary to set this parameter when the crater speed is set properly.
13 Crater speed
It is located at
“
crater segment-current column-wire feed speed (m/min)
”
, and it varies with the
change of the crater current. Therefore, it is unnecessary to set this parameter when the crater current is
set properly.
14 Crater voltage
It is located at
“
crater segment-voltage column-voltage (V)
”
, and it varies with the change of the crater
current or crater speed. Beside, this parameter can be adjusted independently within a certain range.
15 Post-flow time
It is located at
“
postposed segment-voltage column-time (s)
”
, and users can set it according to their
own technical requirements.
Parameters in pulsed MIG/MAG
There are 16 adjustable parameters in pulsed 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. Nine of the 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.
For most of the parameters in pulsed MIG/MAG, see the MIG section above for reference. While a few of
