4.2.3 reMote control MoDule (optIonal)
pn-0558002605 (figure 16)
This optional control panel mounts to the front of the power
source to the right of the main power switch (see Figure 13).
The remote receptacle is designed for Tig current control
using a foot pedal or manual thumb control. The module
includes a toggle switch to select between PANEL or REMOTE
control of the welding current and contactor. See Instruction
Literature F15-618.

4.2.4 spool gun control MoDule (optIonal) pn-
0558002606 (figure 17)
This module mounts to the front panel just left of the Mig Gun
trigger connectors and allows the use of either the MT-250SG
or ST-23A spool guns with the Multimaster 300/300X (ST-23A
requires adaptor P/N 37301). The module has a switch to select
either spool gun or regular Mig gun operation. See Table 3 for
MIG Spool Gun Parameters. See Instruction Literature F15-619.

4.3 MIg WelDIng set-up
When the PROCESS switch is placed in the MIG position the
Multimaster 300/300X is set to turn "ON" when the Mig Gun
trigger is depressed.
Step 1. Choose the weld parameters based of the wire alloy,
diameter, material thickness and shielding gas from
Table 3 - MIG PARAMETERS CHART. Set the polarity
as shown in Table 3 for the process being used.
Step 2. Place the WELD PROCESS 1 switch in the MIG (cen-
ter) position then press the PRESET button.
Step 3. Turn the Wire Feed Speed Knob 3 to the desired
speed in the top digital display window.
Step 4. Turn the VOLTAGE 4 knob to the desired arc voltage
in the bottom digital display window.
Step 5. Set the shielding gas flow rate to 35 cfh by pulling
the gun trigger and turning the adjustment knob on
the R-33-FM-320 Flowmeter / Regulator.
Step 6. Pull the gun trigger and start welding. Trim the wire
speed and volts as needed for the desired arc char-
acteristics.
