Selectable Half Wave Shapes
Not only can you choose Sine, Square or Triangular, the Positive
vs. Negative half of the wave shape can be independently
changed.
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.

• Adjustable AC Frequency
• Expanded AC Balance Control
• Selectable AC Waveshapes
• High Speed DC TIG Pulsing
Excellent Welding Performance
Expanded AC Balance
Inverters can be set to a higher ratio of Electrode
Negative (%EN) for:
• Better penetration with narrow bead profile
• Minimized tungsten erosion (keep a sharp point)
• Minimize etching adjacent to the weld
High Speed DC TIG Pulsing
Conventional TIG Pulsing (<10 Pulses per second pps)
• Timed filler metal & consistent bead appearance
• Reduces heat input by alternating between peak current
and background to minimizes distortion
High Speed TIG Pulsing (Up to 2500 pps)
• Increased puddle agitation for improved weld microstructure
• Focused stable arc
• Increased travel speeds
• Reduced heat input
Adjustable AC Output Frequency
Higher Frequency narrows or focuses the arc cone,
allowing precise control of arc and access into tight joints.
Lower Frequency widens the arc cone, minimizing agitation
of base metal.
