For TIG and Stick Welding
The Invertec®V205-T AC/DC is a compact, TIG power source intended
for critical AC or DC TIG welding. From maintenance to production fabrication, to motorsports, aerospace, nuclear piping and shipbuilding, this
feature-packed inverter is flexible enough for almost any job! Variable
AC frequency allows you to focus the arc when precise control is
required. The 115/230V input voltage auto-reconnect makes the V205-T
AC/DC extremely useful almost anywhere in the shop or in the field.

Precision Arc Performance
• Added Stick Crisp Mode for exceptional Fleetweld®5P and 5P+ (E6010)
Performance.
• Improved TIG starting. Now starts DC(-) to maintain a sharp tungsten.
• Adjustable DC strike mode – Allows adjustment of a hotter or colder start
depending on the tungsten diameter.
• AC/DC inverter for TIG with advanced inverter technology to optimize arc
performance.
• Adjustable AC output frequency allows the operator to focus the arc
minimizing the heat affected zone.
• Extended AC Balance Control helps maintain a pointed tungsten to direct
the arc in the weld joint.
• Selectable waveshapes – Square wave for fast travel speeds and
excellent puddle control, sine wave for a traditional softer sounding arc,
triangular wave to reduce the heat input into the weld at low amperages.
• High quality stick welding with such popular Lincoln

• Voltage Reduction Device (VRD). When enabled from the set up menu
• 200 amps @ 40% duty cycle is the highest output rating in this
machine class.
• Auto-reconnects for single phase 115/230V 50/60 Hz input allows
the flexibility to weld in the shop or take in the field where 230V
may not be available.
• Weighs in at a mere 38 lbs. (17.3 kg) making it easy to carry around the
shop or job site.
Simple Controls
• Full featured TIG control – up to 11 variable – including pulse, upslope,
downslope and balance control.
• Easy to read sequence diagram with LEDs displays selected parameter
for easy setting with a single knob.
Outstanding Quality
• Fan-As-Needed (F.A.N.) fan only operates when needed to reduce power

PERFORMANCE
TIG Welding
The ability to adjust Invertec®V205-T AC/DC’s output frequency
allows the operator to control the focus of the arc. This is ideal
for critical welds if trying to minimize the heat affected zone in
the weld. It is also a benefit for welding on cast aluminum where
lower frequency is desired to minimize agitation of impurities in
the base metal.
Start-only high frequency in AC mode minimizes high frequency
noise emissions.
FEATURES
• Selectable high frequency TIG starting for easy arc ignition or
Touch-Start™ DC TIG starting for areas where high frequency
emissions are a concern.
• Hidden start up menu offers the following additional controls:
– Preflow time for purging gas lines is adjustable between 0 and
25 seconds. Factory preset at 0.5 seconds.
– Selectable AC wave shapes.
