Specs
The Power of Blue® .
Infinite amperage control allows
precise weld output adjustment; you
always get the exact heat you need to
produce a better weld.
Superior 6010 Stick electrode
performance offers reliable puddle
control with open root, full-penetration
welding.
Control-circuit overload breaker allows
for quick resetting and eliminates the
need to keep fuses on hand.
High/low output terminals conveniently let
you choose between two different amperage
ranges for improved output control.
Two wide amperage ranges for fine
adjustment allows exact control of
weld amperage.
Remote amperage control
receptacle can easily connect
remote amperage control.
Easy-to-install running gear has
large wheels for smoother mobility.
Built-in Hot Start™makes it easy to
start difficult-to-start Stick electrodes,
such as E6010 and E7018.
Power source is warranted for 3 years, parts and labor.
Original main power rectified parts are warranted for 5 years.
Superior arc welding performance
provides outstanding Stick welding and
eliminates the need for rewelds.
