Multi-Weld
™
350
Connect Several DC+ Welders to One Power Supply
Inverter Racks
Ideal for grouping several inverter power sources in
a portable industrial-grade package. These inverter
racks are constructed of heavy gauge square tubular
steel to ensure long life, yet maintain an extremely
compact size.

The Multi-Weld
™
350 system offers a cleaner, safer job site, and allows operators to have high
performance welding control right where they need it—at the arc.
• 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, and electrode type
selection (E7018 and E6010).
• Three-year warranty on parts and labor.
