Lincoln Electric Multi-Weld 350 Brochure & Specs

Multi-Weld
Connect Several DC
The Multi-Weld 350 is a 350 amp, DC+, 100% duty cycle welder capable of
CV-wire, CC-stick or arc gouging. With its high efficiency, the Multi-Weld 350
offers an entirely new and better way to build large structures. This unique
system offers a cleaner, safer job site, and allows operators to have high
performance welding control right where they need it — at the arc.

Processes (DC Processes Only)
Stick MIG Flux-Cored
Advantage Lincoln
• Independent arcs. Starting or stopping one Multi-Weld doesn't
affect the welding of the others.
• The Multi-Weld 350 is capable of continuous operation at 350
amps in 122°F (50°C) air temperature.
• No control cables are needed. Single weld cable output from the
power source to one or several Multi-Weld 350s.
• Controls are located close to the operator for quick access.
• High efficiency design uses less than half the power of other
grid systems.
• Lincoln Chopper Technology™ for quality welds with
instant control of the arc for superior welding results.
• Constant voltage (CV) for MIG or flux-cored wire welding.
• Constant current (CC) for stick welding or arc gouging.
• Additional stick welding controls include hot start, arc force,
electrode type selection (E7018 and E6010).
• Arc gouging capability with a single Multi-Weld 350 and up to
5/16" (8.0mm) electrode, or with paralleled units for up to 700
amps of power using a 3/8" (9.5mm) electrode.
• Manufactured under a quality system certified to ISO 9001
requirements and ISO 14001 environmental standards.
• Three-year warranty on parts and labor.
