3) Inductance Setting: 8 (+HARD)
Otherwise, refer to your ‘Recommended Settings Chart’ below for
Wirespeed, Voltage, and Inductance Settings.
F) Attach Work Clamp connector to 220i.
Check for Positive polarity setting — see picture.
G) Attach Work Clamp to work piece.
4. SET Welding Parameters
OPTIONAL: Installing or Replacing Nozzle or Tip
1.) Unplug the 220i.
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.

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 220i 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.
