4.2.3 STICK WELDING SET-UP
When the PROCESS switch is placed in the STICK
position, the Multimaster 160 turns “ON” the weld
contactor so that power is immediately available to the
output connection. This means that the STICK electrode
holder is “HOT”, and an arc will strike when the electrode
comes in contact with the workpiece or any other object
at ground potential.
When the WELD PROCESS switch is moved to the
TIG or STICK position, electrode becomes electrically
“HOT”. Do not allow the electrode to contact ground
potential until you are ready to make a weld.
Step 1. Choose the weld parameters based on the Stick
Electrode and diameter being used from Table 5
- STICK PARAMETERS CHART.

Step 2. Be sure to set the polarity to DCEP (Electrode
Positive) by placing the Electrode Holder cable in
the Positive connection terminal on the front of
the power source.
In general, choose a polarity based on electrode being
used. Some can be run with straight polarity - electrode
negative. Some can be run with reversed polarity - elec-
trode positive.
Reversed polarity is used when more penetration is re-
quired; typically for thicker material. Straight polarity is used
when you want less penetration; typically for thinner mate-
rial.
Step 3. Place the WELD PROCESS (1) switch in the
STICK (FAR LEFT) position.
Step 4. Adjust the CURRENT (4) knob to the desired weld
current in the top digital display window.
Hot Start gives you a burst of current to ensure easy
arc start. The higher the setting, the bigger the burst.
Step 5. Strike the electrode and start welding. Trim the
welding current as needed for the desired puddle
control.
NOTE: The Wirespeed STICK (2) and Voltage (3) knobs have no
effect in the STICK mode.
