Redefining IPM Teach Point
Purge
And
1 IPM
IPM determines the weld metal
deposition rate.
.
Redefining IPM is not normally
required unless special wire or
unusual joint design is needed.
Use front panel parameter select
button to move > to select IPM. Use
Display Control to select teach
point value.
Press and hold Purge button while
turning Display Control to redefine
the ipm teach point. For example:
there are teach points at 150, 200,
and 250 ipm; the teach point at 200
can be adjusted to a wire feed
speed of 151 to 249 ipm.
2 Vpk − Peak Voltage
Arc voltage during peak current
phase of the pulse waveform. This
determines arc length during
adaptive pulse welding.
3 Apk − Peak Amperage
4 Abk − Background Amperage
Peak and background amperage
depend on the range of the welding
power source.
5 PPS − Pulses Per Second Of
20-400
6 PWms − Pulse Width Of
1.0-5.0 Milliseconds
Use side panel controls to change
pulse parameters. See Menu Guide
for detailed programming steps.
After values are set, strike and
maintain an arc for five seconds.
Do this for each teach point.
End weld by releasing gun trigger,
not by pulling gun out of weld.
Repeat for each custom teach
point.
The taught arc length represents a
Trim (arc length) setting of 50.
Once the teach points are set, the
wire feeder adjusts parameters
between teach points synergically.
