For many Miller (Fig. 3) and Lincoln (Fig. 4) welding power supplies, a 14-pin
connector offers power to the SP-1 module and the trigger signal for contact
closure.
Figure 3
In addition to Miller and Lincoln units, many other manufacturers also utilize
the same type of 14-pin connector, with the same pinouts and clocking.
Consult the power supply owner’s manual and or manufacturer for pin
location and labels.

Once the power is connected and turned on, the gun motor is live. Pull the gun
trigger to engage the motor and use the knob on the SP-1 to adjust the wire
speed.
To measure wire speed, pull trigger for 6 seconds and measure wire length.
Multiply measured length of wire by 10 for true IPM (inches per minute).
Approximate wire speeds, by diameter, to achieve 80-100A @ 18-20VDC,
depending on aluminum wire alloy and power supply output:
.023 wire: 525ipm .030 wire: 425ipm .035 wire: 350ipm
