Unique Features

The Lincoln Power MIG 180c MIG Welder comes with many useful features built in. These features include a unique tool-less design that makes this welder stand out from the rest in its class.

Diamond Core Technology

With Lincoln Electric’s Diamond Core Technology, this welder features an arc that is always forgiving and plenty of voltage range to make welding easier for beginners.

It also creates less splatter and better arc action overall.

Tool-less Design

This welder features no need to use tools when changing the polarity, maintaining the wire drive, mounting the spool, or performing other routine work on the device.

Aluminum Drive

The welder incorporates an aluminum drive and a unique dual drive roll design to create an easy-to-use, accessible setup.

This design reduces the risk of problems such as tangling and knotting while working.

Durable PC Board Protection

The PC board inside this welder nestles beneath a durable plastic tray to resist impact and shock from regular use.

With this design, the welder features a longer lifespan with fewer chances for the inner workings to become damaged.

Flux Core Capabilities

Although this welder features MIG specifications, it also includes flux core capabilities. Simply change the included gun for an aluminum spool gun instead.


Performance & Ease of Transportation

With a powerful performance output and a durable, portable design, the Lincoln Power MIG 180C MIG Welder K2473-2 pleases beginners and professionals both.


Customers who need a welder for home or garage use enjoy working on DIY and art projects with the Lincoln Power MIG 180C MIG Welder.

This welder offers plenty of capabilities to keep a beginner or intermediate hobbyist happy.

Experienced welders enjoy the benefits of working with such a small, portable welder. Professionals use it in their shops to complete precise jobs that are too small for traditional welders.

The durable casing and PC board protection help to create an even longer-lasting machine.

Ease of Transportation

The small size of this welder ensures hobbyists can move it around as needed to complete projects in different locations.

Despite being small, it packs a punch and continually puts out quality results with a lot of power behind each weld.

In comparison to other portable welders, however, the Lincoln Power MIG 180C MIG Welder comes in slightly heavier. It remains a good choice for transportation, but not the lightest option on the market.


Weld Quality and Available Options

The Lincoln Power MIG 180C MIG Welder provides quality weld results regardless of skill level.

Beginners learn to create beautiful welds in a short time with this product, and experienced hobbyists enjoy challenging the boundaries of their skills.

Customers change and adjust the settings easily with this product.

The Lincoln Power MIG 180C MIG Welder K2743-2 comes in just one option. However, it includes the following upgrades and potential add-ons:

  • Magnum Pro 100 SG Spool Gun: This spool gun comes as an add-on at an additional cost. It allows customers to use aluminum wire and flux core welding with the same machine.
  • Spot Timer Kit: This add-on allows the customer to set a short weld time and complete it with one pull of the welding trigger. It helps improve thin, small welding jobs.

Ease of Maintenance, Repairs & Warranty

The Lincoln Electric company makes it easy for existing customers to locate parts for repairs and replacements. The company web site offers a search via serial number, and the company also takes calls daily to help with this service.

The Lincoln Power MIG 180C MIG Welder requires regular maintenance, like any welding machine. It does not include interior serviceable parts, however.

If something malfunctions inside the machine, it must be serviced by a professional.

Once a month or more if needed, use compressed air to blow dirt and dust from the vents in the welder. Check the guide tube to see if it needs to be replaced, cleaned, or repaired.

Every 300 pounds of solid wire or 50 pounds of flux core wire, clean the gun cable. Take the contact tip off the gun and remove the gun cable from the machine. Use compressed air to flush out the cable.

The motor, fan, and wire spindle do not need routine maintenance.

This welder features a standard limited warranty. The warranty covers 7 years of parts and labor for the power rectifiers and 3 years of parts and labor for the machine itself.

It also covers 1 year for wire feeds, welding accessories, and wire. The warranty covers 90 days for the gun and cable and 30 days for any consumable items.

Contact Lincoln Electric at 1-888-935-3877 for more information about this warranty.
