The preprogrammed wire types, wire diameters and shielding gases are
listed in Table 4-2.
The TRIM allows the operator to fine tune the pulse arc length and optimize the
welding. When the PROCESS switch is placed in the MIG position and the MIG
MODE switch is placed in the PULSE position, the Multipower 460PULSE is set
for CC over CC (constant current) pulse welding. The power source will output
open circuit voltage (OCV) when the Mig Gun trigger is depressed. The
Multipower 460PULSE provides a TRIM from either the wire feeder or power
source depending on the position of the PANEL/REMOTE switch characteris-
tics. The TRIM adjustment is calibrated such that the preprogrammed synergic
pulse data is approximately at the 12 o'clock position of the TRIM knob. The
operator should preset the voltage control on the wire feeder to the 12 o'clock
position and adjust for best arc characteristics.
The operator can change to STANDARD MIG (CV) by simply moving the MIG
MODE switch to the STANDARD position.
