Lincoln Electric LE31MP K3461-1 is a 120 V multiprocess welder for MIG, self-shielded flux-cored, stick and DC TIG work in home workshops, farms, repair shops and autobody applications.
Key Features and Benefits
- 120 V single-phase input suits the documented power supply; confirm the circuit can provide the required current.
- Separate MIG, stick and DC TIG output ranges support choosing settings for the process.
- Two-knob controls provide direct welding adjustments.
- Included Magnum PRO 100L gun, work cable and electrode holder support the listed MIG, flux-cored and stick configurations.
- An optional TIG torch and foot pedal add DC TIG capability; an optional compatible spool gun supports aluminum wire.

Applications and Compatibility
For shop, farm, home and autobody welding. DC TIG is identified for steel and stainless steel; do not treat this machine as an AC TIG welder for aluminum. Aluminum MIG requires the compatible spool-gun configuration. Match wire, shielding gas and polarity to the process and material.
What Is Included
- Magnum PRO 100L gun with 10 ft cable assembly (K530-7)
- .025 in and .035 in tapered contact tips, three of each
- MIG gas nozzle and Innershield gasless nozzle
- 8 in spool spindle adapter and .025–.035 in dual-track drive roll
- Gas regulator and 52 in hose for argon/CO2 blend gas
- Sample .025 in SuperArc L-56 MIG wire and .035 in Innershield NR-211-MP flux-cored wire
- Work clamp with 10 ft cable; electrode holder with 10 ft cable
- Instruction manual and Quick Start guide
Setup and Documentation
Follow the machine instructions for input power, wire-drive setup, gas connections and process polarity. TIG torch, foot pedal and spool gun are optional accessories, not part of the documented base package. CO2 shielding gas requires the specified bottle adapter. Do not treat maximum amperage as continuous output.
Frequently Asked Questions
Is this an AC TIG welder?
No. The documented TIG process is DC TIG; steel and stainless steel are identified applications.
Is a spool gun included?
No. The manufacturer identifies the compatible spool gun as an optional accessory for aluminum MIG welding.
Are the TIG torch and foot pedal included?
No. They are sold separately for the DC TIG configuration.
Does 140 A mean continuous output?
No. The MIG range extends to 140 A, while the stated rated MIG output is 95 A at 18.75 V and 60% duty cycle on 120 V input.
