The Power of Blue.
Two wide amperage ranges for fine
adjustment allows exact control of
weld amperage.
Superior arc welding performance
provides outstanding Stick welding and
eliminates the need for rewelds.
Remote amperage control
receptacle can easily connect
remote amperage control.
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.
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.
Control-circuit overload breaker allows
for quick resetting and eliminates the
need to keep fuses on hand.
