The teach mode allows the user to
create custom pulse programs. The
teach mode has 15 teach points. At
each teach point, the user can ad-
just five parameters to shape the
pulse waveform of the weld output.
The five parameters are: IPM
(MPM), Apk, Abk, PPS, and
PWms.
Apk, Abk, PPS, and PWms acting
together provide the energy neces-
sary to burn off welding wire at a set
wire feed speed. The graph below
shows that as wire feed speed in-
creases, energy increases (Apk,
Abk, PPS, and PWms acting syn-
ergically).
Under some conditions, the wire
feeder limits wire feed speed to
maintain all pulse parameters with-
in the capability of the system.
