PHASE

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 Fleetweld

5P, 35, 37, 180 and Excalibur®7018.

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.
