2. SETUP Gas Regulator
A) Attach the regulator to the cylinder valve and tighten securely with a wrench.
B) Connect the 141i gas hose to the gas outlet on the regulator.
C) Purge the regulator and 141i gas hose by SLIGHTLY opening the
cylinder valve for 3-to-5 seconds and then close.
D) Connect the 141i gas hose to the gas port on the back of the 141i.
Wrench tight to 1/4 turn.
E) Slowly and carefully open the cylinder valve until the maximum pressure shows
on the High-Pressure gauge.
F) Adjust regulator knob on the Low-Pressure gauge so the needle is
in the MIG, (Green Section).
3. SETUP MIG Gun
A) Loosen Thumb Screw (located inside side panel), then fit the wire into the MIG Gun
connector as you slip the Connector into the MIG Gun Adaptor, then tighten the
Thumb Screw (clockwise).
B) Fit the 8 pin plug into the 8 pin socket and rotate
threaded collar fully clockwise to lock the plug into position.

1. INSTALL Wire Spool
A) Drive Roll installed on machine is .030". If running other wire sizes and wire types
please see Operators Manual.
B) Install Spool
• Open side panel of 141i and mount the 8" diameter Wire Spool on Spool Hub.
Ensure Wire Spool seats onto Spool Hub Pin. (See Operator's Manual for
alternate 8" and 4" diameter spool set up.)
• Hand feed the wire from the spool into the Inlet Guide. (Wire is under tension.)
• Tilt the Wire Drive Tension Screw Arm toward the front of the machine and
feed the wire through the Outlet Guide until it comes out the front of the 141i about 3".
• Return the Wire Drive Tension Screw Arm to the upright position locking the
Pressure Roller Arm underneath it. Ensure wire is seating in drive roll groove.
• Turn Wire Drive Tension Screw clockwise until drive roll grips wire.

I) Lay the MIG Gun out so the cable is straight with NO twists or kinks.
MIG GUN
• Unscrew nozzle and pop out the tip from MIG gun.
• Point the MIG Gun AWAY from your body. Press and hold the
MIG Gun trigger. The wire will advance through the cable and
out the MIG Gun conductor tube. Release the MIG Gun trigger.
• Reinstall MIG Gun tip and nozzle.
• Trim the wire at the MIG Gun nozzle to desired stick out.
TRIGGER
• Close the 141i side panel.
4. SET Welding Parameters
A) Select MIG PROCESS.
B) Determine what material type and thickness you plan to weld (24 ga. through 1/16" thickness).
C) Determine what wire type and diameter you plan to use (.030"recommended).
D) Determine what shielding gas you plan to use (75% Ar/25% CO
E) Quick Start Parameters:
for 16 gauge (1.6 mm)
1) Wirespeed Display: 220
2) Voltage Display: 16.0 (16V)
3) Inductance Setting: 10 (+HARD)
Otherwise, refer to your 'Recommended Settings Chart' below for
Wirespeed, Voltage, and Inductance Settings.
F) Attach Work Clamp connector to 141i.
Check for Positive polarity setting — see picture.
G) Attach Work Clamp to work piece.
