Overview of Features

Diamond Core Technology: A patented piece of equipment which will “deliver a forgiving arc” helping you lay beautiful beads. This unit definitely has a stable arc, which makes using this unit much more pleasurable.

Industrial Cast Aluminum Drive: Made from one piece of Aluminum ensures durability, and unlike plastic counterparts won’t get brittle with heat or age. The closed-drive motor improves torque and delivers trouble free performance, as it’s shielded from contaminants.

Tool-less Design: No need to carry around any extra tools for input power changes, wire spool mounting, wire drive servicing and polarity changes. Convenient if you don’t own a range of tools, and no hidden surprises if something goes wrong.

PC Board Protection: Sensitive components are sealed from airbourne contaminants, as they’re sealed in a tough plastic tray. According to Lincoln this method of sealing electronics provides shock resistance, a great bit of reassurance should you drop/move the unit.

Spool Gun Ready: When connecting a gun to this machine, it will automatically detect if it’s a MIG or Spool Gun and adjust accordingly. Reducing the need for user input, and remembering another setting to change.

Will this welder suit my needs?

Due to the maximum output being 140A, and only supporting 115V input voltage does limit the application of this welder. If you only require thin metal such as car body panels, or for DIY projects this machine would be perfect. Compared to other models on the market, Lincoln is a briliantly designed machine as well as a respected brand. This makes the warranty Lincoln offer more attractive, you can find exact details of what is covered here.

Due to the input power limitation, this would be best suited to a domestic setting or light shop work. The Power MIG range by Lincoln offer units with higher output amperage and improved duty cycles, however this may be unescessary depending on your requirements.
