Invertec® V310-T AC/DC
TIG WELDER
Excellent Welding Performance
New Cart
• Adjustable AC Frequency
• Expanded AC Balance Control
• Selectable AC Waveshapes
• High Speed DC TIG Pulsing
The Invertec® V310-T AC/DC is the most technologically
advanced AC/DC TIG welder in its class. It fits the bill
for serious fabrication, maintenance, and production
work. Its compact, lightweight size makes it ideal
for field applications like advanced motorsports,
aerospace, shipbuilding, and construction.
Makes a Complete Solution
• Dynamic LCD Display (patent pending)
• Adjustable AC Frequency and Selectable Waveshapes
• Soft, Crisp and AC Stick Modes
Adjustable AC Output Frequency
Expanded AC Balance
Higher Frequency narrows or focuses the arc cone,
Inverters can be set to a higher ratio of Electrode
Negative (%EN) for:
allowing precise control of arc and access into tight joints.
• Optional Cool Arc® 35 “Smart” water cooler
• 208-460 1/3 phase auto-reconnect
Lower Frequency widens the arc cone, minimizing agitation
of base metal.
• Better penetration with narrow bead profile
• Minimized tungsten erosion (keep a sharp point)
• Minimize etching adjacent to the weld
• High efficiency inverter

Selectable Half Wave Shapes
High Speed DC TIG Pulsing
Conventional TIG Pulsing (<10 Pulses per second pps)
• K2666-1 TIG Mate™ 17 Air Cooled TIG Torch Starter Pack
• K870 Foot Amptrol®
Not only can you choose Sine, Square or Triangular, the Positive
vs. Negative half of the wave shape can be independently
changed.
• Timed filler metal & consistent bead appearance
• K963-3 Hand Amptrol®
• More options at end of section
• Reduces heat input by alternating between peak current
and background to minimizes distortion

Options
Example: Select a square positive wave to minimize high peak
current that erodes the tungsten and select a triangular wave
for the negative half to minimize heat input to the weld.
