please see Operators Manual.

B) Install Spool

• Open side panel of 140i 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 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.

2. SETUP Gas Regulator

A) Attach the regulator to the cylinder valve and tighten securely with a wrench.

B) Purge the regulator by SLIGHTLY opening the cylinder valve for 3-to-5 seconds

and then close.

C) Connect the 140i gas hose to the gas outlet on the regulator. Wrench tight 1/4 turn.

D) Slowly and carefully open the cylinder valve until the maximum pressure

shows on the High-Pressure gauge.

E) Adjust regulator knob on the Low-Pressure gauge so the needle is

in the MIG, (Green Section).

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

recommended).

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 140i.

Check for Positive polarity setting — see picture.

G) Attach Work Clamp to work piece.

3. SETUP MIG Gun

4. SET Welding Parameters

OPTIONAL: Installing or Replacing Nozzle or Tip

1.) Unplug the 140i.

2.) Unscrew worn nozzle and pop out the tip.

3.) Slide new contact tip into the conductor tube end.

(Tip does not screw in.)

4.) Replace the nozzle. Hand tighten (Nozzle secures tip).

NOTE: For proper operation the nozzle MUST be tight.

5.) Trim wire to desired stick out.

140i Shut Down

A) Turn the Power Switch OFF.

(Located on the rear of the machine.)

B) Turn cylinder valve OFF and

bleed downstream gas line by loosening

hose at back of 140i.

When nished welding, remember to

properly shut down the 140i.

C) Turn the Power Switch ON. (Located on the rear of the machine.)

D) Select MIG PROCESS.

E) Select 2T for TRIGGER.

F) Turn WIRESPEED Dial to Five. (Halfway between 4 and 6 marks)

G) Switch the LOCAL/REMOTE switch inside the wire feed

compartment to LOCAL.

H) Lay the MIG Gun out so the cable is straight with NO twists or kinks.

• 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.

• Close the 140i side panel.

Read and understand this entire guide, the Operating Manual and your

employer’s safety practices before installing, operating, or servicing the equipment.

While the information contained in this guide represents the Manufacturer’s

best judgment, the Manufacturer assumes no liability for its use.

Refer to the 140i Operation Manual for detailed safety and operation instructions.

WARNINGS and CAUTIONS

• ELECTRIC SHOCK can kill. Touching live electrical parts can cause fatal shocks or severe burns.

• Incorrectly installed or improperly grounded equipment is a hazard.

• The MIG welding wire and work circuit is electrically live whenever the output is ON.

• The MIG wire, wire reel, drive roll housing, and all metal parts touching the welding wire are

electrically live whenever the output is ON.

• STICK Electrode is electrically live as soon as it is in the Electrode Holder.

• Never stand in front of or behind a regulator when opening the cylinder valve!

• DO NOT attach or use the regulator if oil, grease, ammable substances, or damage is present!

Stand to the side of the cylinder opposite the regulator when opening the cylinder valve.

Keep the cylinder valve between you and the regulator.

• NEVER use a compressed gas cylinder without a pressure reducing regulator attached to the cylinder valve.

• Always use a regulator designed for the type gas used.

• DO NOT point MIG Gun at your face.

• Maintain an adequate distance of the wire from metal objects to avoid burnbacks to conduit or conductor tube.

• Always wear a welding helmet tted with a proper shade of lter (see Safety Standards in the Operation manual) to

protect your face and eyes when welding or watching, and safety equipment when welding.

NOTES

• If the wire does NOT advance through the MIG Gun, release MIG Gun trigger, lay the gun down,

unplug the machine and adjust the Wire Drive Tension Screw inside the 140i side panel.
