AC TIG Features
Independent amplitude/amperage
control allows EP and EN
amperages to be set independently
to precisely control heat input to
the work and electrode.
Balance control provides adjustable
oxide removal which is essential
for creating the highest quality
aluminum welds. These models
provide extended ranges.
Frequency controls the width of
the arc cone and can improve
directional control of the arc.

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.
Meter calibration allows digital meters to
be calibrated for certification.
120-volt auxiliary power
receptacle for cooling system
or small tools.
Wind Tunnel Technology™
protects internal electrical
components from airborne
contaminants, extending the
product life.
Fan-On-Demand™ power source
cooling system operates only when
needed, reducing noise, energy use
and the amount of contaminants
pulled though the machine.

AC Waveforms

Dynasty 350 Complete Package
with Wireless Foot Control

Lift-Arc™ start provides AC or DC
arc initiation without the use of
high frequency.
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.
Program memory features nine
independent program memories
that maintain/save your parameters.
Auto-postflow adjusts the length of
postflow time based on the amperage
setting, shielding your tungsten
and eliminating the need to set the
postflow time.

AC/DC Stick Features
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.
Hot Start™ adaptive control provides positive arc starts
without sticking.
AC frequency control adds additional stability when Stick
welding in AC for smoother welds.

Advanced 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.

DC TIG Features
Exceptionally smooth and precise
arc for welding exotic materials.
Pulse. Pulsing can increase puddle
agitation, arc stability and travel
speeds while reducing heat input
and distortion. These models
provide extended ranges.

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