Mark VI Multiple Arc
Welding System
Issued January 2006 • Index No. DC/9.8
Work connections are electrically isolated
from the frame, and service panels in
chassis provide easy access to internal
parts for routine maintenance.
Capable of four to six welding arcs,
Miller’s unique modules are designed
for easy removal and connection.
If you need only four arcs today,
purchase the Mark VI-2. If you
have a requirement for more arcs,
additional modules (CC or CV)
are available for purchase.
Optional Low OCV in CC/CV modules reduces maximum
open-circuit voltage to 26 volts in CC and CV modes when
not welding.

Adjustable arc control lets you get in
tight without sticking the electrode. An
electrode compensation circuit ensures
arc control performance regardless of
the electrode size.
Multiple capabilities CC or CC/CV.
Versatility and outstanding arc
welding performances in both CV
(MIG) and CC (TIG and Stick). The
CC/CV module has a high quality
arc for welding with cored wires.
Miller does not recommend that
the CC/CV module be used for short
circuit transfer MIG welding. The CC
module has the same great arc
characteristic as the Gold Star 302.
Operator identification label helps
operators remember who is using
which module.
Welder is warranted for 3 years, parts and labor.
Original main power rectified parts are warranted for 5 years.
14-pin receptacle provides quick, direct
connection to Miller wire feeders and
accessories.
Weighs less than one ton which
makes it portable when secured on a
flatbed, construction truck, or when
moved by one-ton hoist. Fits through
36 in (914 mm) door opening.
60 Hz models have two 115 V GFCI duplex
receptacles which supply 15 amps of
auxiliary power. 50 Hz models have one
220 V and one 115 V duplex receptacle.
Line voltage compensation keeps
output power constant even if primary
input power varies by ±10%, ensuring
consistent weld performance.
Hot Start™makes it easy to start difficult-
to-start Stick electrodes, such as E-6010
and E-7018.
