The Power of Blue®.
Standard gas solenoid
controlling gas flow.
Totally enclosed, impactresistant, flame-retardant
case provides strength
and durability, protecting
components and weld wire
from moisture, dust and
contaminants.
Remote voltage control — standard.
Quick-change
drive rolls are
easy to change —
no tools required.
Drive roll accessibility
makes it easy to install
wire, adjust tension and
change drive rolls.
Versatile feeders can
run wire diameters up to
5/64 in (2.0 mm).
Gas purge purges gas
line without feeding wire,
or energizing weld wire
with OCV.
Thermal overload
protection protects motor
and control circuit against
possible damage due to
overloading conditions,
or loose cable connections.
Digital meter option
available for wirefeed
speed or voltage display.
Improved trigger strain
relief
Component assembly
is easily removed for
servicing.
Specifications (Subject to change without notice.)

Updated front panels!
Improved trigger strain relief!
