Description

This Lincoln Electric K5255-1 welder runs on 120V flux-core wire for light to medium welding projects.

Product Overview

The Lincoln Weld-Pak 90i FC turns a home shop into a capable welding station, thanks to its direct hookup to a standard 120V outlet. Compact and light at 15 lb, it plugs in and welds within minutes.

The flux-core process eliminates the need for shielding gas, a real advantage for welding outdoors or in a poorly ventilated garage. The adjustable 20 to 120A amperage covers light-gauge steel up to 0.25 in thick.

Care and Usage

First Use

Follow these steps before your first weld:

  1. Install the flux-core wire spool matching your chosen diameter (0.030 or 0.035 in).
  2. Set the amperage between 20 and 120A based on the thickness of the metal.
  3. Attach the ground clamp directly to the workpiece, never to the workbench.
  4. Run a test weld on scrap metal before starting your actual project.

Regular Maintenance

After each use:

  • Clean weld spatter off the nozzle.
  • Check the condition of the contact tip.
  • Store the gun away from dust.

Wire management:

  • Store the spool in a dry place to prevent rust.
  • Replace the wire as soon as it shows signs of oxidation.

Cleaning and Maintenance

  1. Ventilation: clean vents with compressed air to prevent overheating.
  2. Cables: regularly check the gun and ground cables for wear and cracking.
  3. Contact tip: replace as soon as the opening widens from wire wear.

Safety Precautions

For your safety:

  • Welding helmet with proper shade required at all times.
  • Proper ventilation: never weld in an enclosed space without airflow.
  • Dry environment: never use the welder in rain or damp conditions.
  • Unplug: always unplug the unit before any maintenance.

Storage Tips

Short-term storage:

  • Dry location, between 5°C and 40°C.

Winter storage in Canada:

  • Avoid extreme temperature swings.
  • Let the welder return to room temperature after cold transport before use.

Frequently asked questions about the Weld-Pak 90i FC welder

What steel thickness can this welder handle?

Up to 0.25 in (1/4 in) of steel thanks to its adjustable amperage of 20 to 120 A. Thicker pieces require a welder with higher amperage.

Does this welder need a gas cylinder?

No. The Weld-Pak 90i FC uses the flux-core process, which requires no shielding gas. That's an advantage for welding outdoors or without access to gas cylinders.

Is this welder compatible with solid MIG wire?

No, this model is designed exclusively for flux-core wire only. For gas-shielded MIG welding, a multi-process welder is required.

What's included in the box?

The welder ships with a welding gun, 0.030 and 0.035 in contact tips, a gasless nozzle, a drive roll and a ground clamp. See our welding gloves and welding helmets, sold separately.

What warranty comes with this welder?

Lincoln Electric offers a 1-year limited warranty covering manufacturing defects. Équipement Industriel Polar adds a 30-day satisfaction guarantee.

Is this welder suitable for beginners?

Yes. Its simplified interface and direct connection to a standard 120V outlet make it a popular choice for learning to weld, whether in a home shop or on the farm.

Can this welder be used in an unheated garage in winter?

The welder works well in a shop setting, but it's best to let it return to room temperature after cold transport before using it, to protect the electronic components.
