This durable, heavy-duty multiple operator welding
system drives eight modules from a single main
transformer. Each welding module features remote

control capabilities, and a wide range of amperage
settings. Modules can be easily paralleled for extra
welding power.

The Mark VIII

®

-2 operates 24 hours a day with
exceptional productivity and durability. Housed
in a rugged steel enclosure, this performer has
repeatedly proven its ability to withstand the
punishment of the worst weather and construction
site elements.

Features Benefits

MagAmp technology

Eight welding modules

Multiple capabilities

Steel frame
115 VAC duplex receptacle

MagAmp technology provides good arc and puddle control and offers years of reliable operation. The tough mechanical
components handle the most demanding work environments.

Each module offers up to 300 amps output, or parallel modules for extra welding power. Each module can be connected
for either DC straight or reverse polarity.*

The Mark VIII-2 can handle Stick, DC-TIG welding, and wire welding (FCAW and MIG) with a voltage-sensing feeder.
You can also use this one unit for Air Carbon Arc cutting and gouging.

Rugged and durable enclosure protects system and simplifies transportation of eight welding arcs.
Supplies 10 amps of auxiliary power.
