The Power of Blue

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.
