TIG/Stick Welding
Power Source
Input Power 208 – 575 V, 3- or 1-Phase Power
Amperage Range 1 – 280 A (DC)
2 – 280 A (AC)

Rated Output 200 A at 28 V, 60% Duty Cycle

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

AC TIG Features
Extended AC balance (50–99%)
controls the amount of oxide cleaning
(amperage time in EN) which is essential
for high quality welds on aluminum.
AC frequency (20–400 Hz) controls
the width of the arc cone and the force
of the arc.

for the latest software upgrades
and expansions.

Pro-Set™ feature (professional
settings) eliminates the guesswork
when setting weld parameters.
Use Pro-Set when you want
the speed, convenience and
confidence of pre-set controls.
Simply select the feature and
adjust until Pro-Set appears on
the display. The Pro-Set feature is
available for Balance, Frequency,
Pulse, and DIG parameters.
Sleep timer conserves electricity.
This programmable feature will
power down the machine if it sits
idle for a specific time.

aluminum filler.

DC TIG Features

Meter calibration. Digital meters can be calibrated to a
standard device for certification.
Allows 208 – 575 V input voltage hookups.
Cooler Power Supply (CPS). An
integrated 120-volt dedicated-use
receptacle to power the Coolmate™ 1.3.
The power switch on the Dynasty also
activates the receptacle to help prevent
torch failure. Available on select models,
see page 6.

Advance Squarewave, fast
freezing puddle, deep
penetration and fast travel speeds.
Soft Squarewave for a soft
buttery arc with maximum
puddle control and good wetting action.
Sine wave for customers that
like a traditional arc. Quiet with
good wetting.
Triangular wave reduces the
heat input and is good on thin
aluminum. Fast travel speeds.

Wind Tunnel Technology™ protects internal electrical
components from airborne contaminates, extending the
product life.
Fan-On-Demand™ power source cooling system operates
only when needed, reducing noise, energy use and the
amount of contaminates pulled though the machine.

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

Exceptionally smooth and precise arc
for welding exotic materials.

Stick Features (AC/DC)
Tailored arc control (DIG) allows the
arc characteristic to be changed for
specific applications and electrodes.
Smooth running 7018 or stiffer, more
penetrating 6010.
Hot Start™ adaptive control provides
positive arc starts without sticking.
AC frequency control adds stability for
smoother welds when AC Stick welding.
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.

Power source is warranted for 3 years, parts and labor.
Original main power rectifier parts are warranted for 5 years.
