Multi-Weld 350 MULTI-OPERATOR TM Connect Several DC+ Welders to One Power Supply. 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 Description Gouging Output Input 80 VDC Advantage Lincoln Recommended General Options • Independent arcs. Starting or stopping one Multi-Weld doesn’t affect the welding of the others. Distribution Box, Welding Cable Connectors, Input Cables, Remote Output Control, Undercarriage • 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. Recommended Power Source Options SAE-400, Vantage 500, DC-655, DC-1000, DC-1500 • 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). Recommended Wire Feeder Options LN-15 Across-the-Arc, LN-25 Across-the-Arc Order K1735-1 Multi-Weld 350 • 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.

A CLOSER LOOK SUPERIOR WELDING PERFORMANCE • Superior starting compliments the soft, stable welding arc yielding very low spatter levels. Chopper control has an extremely fast response for tighter output control than tradition weld control. Chopper Technology for extremely fast response for smoother output control. • High efficient design and low input current draw means more welding. Chopper Technology CV-Wire Mode Traditional Reactor Technology CV-Wire Mode Traditional weld control is more variable around the desired output. Patented and award-winning Lincoln Chopper Technology delivers...
