4.2.1 MIG WELDING SET-UP

When the PROCESS switch is placed in the MIG position
the Multimaster 160 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 Filgure 10 for the
process being used.
Step 2. Place the WELD PROCESS (1) switch in the MIG
(FAR RIGHT) position.
Step 3. Turn the Wire Speed Knob (2) to the desired
speed.
Step 4. Turn the VOLTAGE (3) knob to the desired arc
voltage.
Step 5. Pull the gun trigger and start welding. Trim the
wire speed and volts as needed for the desired
arc characteristics.
Option: If using one, set the shielding gas flow rate to 35
cfh by pulling the gun trigger and turning the ad-
justment knob on the R33-FM 580 Flowmeter.
