Multi-Operator - Lincoln Electric AC-225C Specification Sheet

Multi-Weld
Connect Several DC+ Welders to One Power Supply
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
• 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
• 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 ®
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.

Inverter Racks
Featuring Invertec ®
with Tweco ® Output Connectors
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.
• One easy connection allows power sources to be
connected with one easy primary drop.
• The power sources are factory installed in the rack
and wired to the main power distribution panel.
• Entire system meets National Electrical Code (NEC).
• 200 amp, 600 volt, 3 phase main disconnect switch.
• Individual fuses provide overcurrent protection for
each power source.
• Standard length input cord insures the power sources
can be placed in any position on the rack.
• Three-year warranty on parts and labor.
