TIG/Stick Welding
Power Source
Input Power 208 – 575 V, 3- or 1-Phase Power
Amperage Range 1 – 280 A (DC)
Rated Output 200 A at 28 V, 60% Duty Cycle
Net Weight 47 lb. (21.3 kg)

Upgradeable and expandable.
Front panel memory card data
port provides the ability to easily
upgrade software and expand
product features.

DC TIG Features
Pulse. Pulsing can increase
puddle agitation, arc stability
and travel speeds while reducing
heat input and distortion. DX
models provide extended ranges.

for the latest software upgrades
and expansions.

Exceptionally smooth and
precise arc for welding exotic
materials.

Pro-Set™ eliminates the guesswork
when setting weld parameters.
Use Pro-Set when you want the
speed, convenience and confidence
of preset controls. Simply select
the feature and adjust until Pro-Set
appears on the display.

DC Stick Features
Dual schedule allows operators
to switch welding parameters
for specific electrodes without
readjusting the machine,
minimizing downtime and
enhancing quality. Base model
only (not DX).

Sleep timer conserves electricity.
This programmable feature will power
down the machine if it sits idle for a
specific time.
Maxstar 280

Allows for any input voltage hookup
(208 – 575 V) with no manual linking,
providing convenience in any job setting.
Ideal solution for dirty or unreliable power.
Cooler Power Supply (CPS). An
integrated 120-volt dedicated-use
receptacle to power the Coolmate™ 1.3.
The power switch on the Maxstar also
activates the receptacle to help prevent
torch failure. Available on select models,
see page 6.

Maxstar 280 DX

Wind Tunnel Technology™ protects internal electrical
components from airborne contaminates, extending the
product life.

DIG control allows the arc
characteristics to be changed
for specific applications and
electrodes. Lower the DIG
setting for smooth running
electrodes like E7018 and
increase the DIG setting for
stiffer, more penetrating
electrodes like E6010.

Fan-On-Demand™ power source cooling system operates
only when needed, reducing noise, energy use and the
amount of contaminants pulled though the machine.

Hot Start™ adaptive control
provides positive arc starts
without sticking.

Meter calibration allows digital meters to be calibrated
for certification.

Stick-Stuck detects if the
electrode is stuck to the part
and turns the welding output
off to safely and easily remove
the electrode. Menu selectable.

Blue Lightning™ high-frequency (HF)
arc starter for non-contact arc initiation.
Provides more consistent arc starts and
greater reliability compared to traditional
HF arc starters.

Power source is warranted for 3 years, parts and labor.
