WIRE FEEDER/WELDERS

 

Power MIG®. The Professional’s Cho

Home projects and repair, sheet metal autobody work, farm and small shop welding—the Power MIG® 140C designed fo 120 volt household power does it all!

Use the continuous voltage control to precisely dial in the settings some thin sheet metal and aluminum applications require for optimal results.

Diamond Core Technologyand the rugged drive system aid arc performance for MIG welding on thin gauge steel, stainless and aluminum. Or, use gas-less flux-cored welding for deep penetration on thicker steel, even outdoors! Compare performance, features and price and you’ll agree. . . Power MIG®. The Professional’s ChoiceSM!

Advantage Lincoln

Superior Arc Performance:

Exclusive Diamond Core Technology™ delivers an outstanding arc you notice immediately compared to competitive models:

Great arc starts make getting started easy.

Wide voltage ‘sweet spot’ gives you a very forgiving arc, so setting controls is a snap.

Extremely low spatter reduces clean-up.

Outstanding aluminum & stainless performance, not just mild steel.

Wide 30-140 amp welding output range is the highest output in 120 volt input power welder class.

MIG weld 24 gauge up to 10 gauge (.135”) sheet metal in a single pass. Weld up to 5/16" steel using self-shielded Lincoln Innershield wires (FCAW-S).

Professional Features:

Industrial Cast Aluminum Drive features:

Dual gear-driven drive rolls for positive traction.

Patented split wire guides for optimal wire alignment.

Brass-to-Brass gun connections for enhanced connectivity.

Large industrial closed-design drive motor for improved torque and trouble-free performance.

Spool Gun Ready – add the optional Magnum®100SG spool gun for reliable operation at the high wire feed speeds aluminum welding demands. No expensive outboard modules required.

No Hassle Tool-less Design – for wire spool mounting, wire drive service and polarity changes.

Get More, Do More – Start out with more contact tips, nozzles, drive rolls and wire electrode for MIG or flux-cored welding.

Innovative contact tip, drive roll and nozzle storage keeps all your consumables close at hand.

Electrically ‘cold’ electrode provides an added measure of operator safety.

Superb Quality:

Patent-pending Power Chassis™ channels airflow to cool power systems, structurally secures key components and traps wires and cables to avoid unnecessary abrasion.

Toughest PC Board Protection in the industry – ‘Potted’ to seal sensitive components from the environment, ‘trayed’ in a tough plastic tray to add rigidity and shock resistance.

Three-year Lincoln warranty. Two-year extended warranty available – (U.S. and Canada only).
