Portable in the shop or at
the job site — at 41 lb the
CST 280 is easily moved
from location to location.
Superior Stick arc performance
even on the difficult-to-run
electrodes like E6010.
Adaptive Hot Start ™ for Stick
arc starts automatically
increases the output amperage
at the start of a weld should
the start require it. Prevents
the electrode from sticking
and creating an inclusion.
Remote amperage control
provided through 14-pin
receptacle on front of the
machine. This permits use
of standard remote
amperage control devices.
Tweco ® or Dinse-style
connectors are available
on the CST 280.
6 ft power cable included.
Easy To Install with a new
switch on the outside of the
package, the machine can be
changed between low and high
input voltage ranges. Also,
since the switch is on the
back, input voltages can be
changed without removal
from inverter racks.
Optional 4- or 8-pack racks
are available for multiple
operator applications.
These are commonly used
in construction and shipyard
applications. All CST controls
including the power switch
are located on front of the
machine for easy access.
Power source is warranted for 3 years, parts and labor.
Original main power rectified parts are warranted for 5 years.
