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 Technology
aid arc performance for MIG welding on thin gauge steel,
tainless and aluminum. Or, use gas-less flux-cored
s
welding for deep penetration on thicker steel, even
outdoors! Compare performance, features and price and
you’ll agree. . . Power MIG

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
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 sen-
sitive 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).
