Accu-Pulse
Accu-Pulse® is standard on all Auto-Axcess™ E models.
The Accu-Pulse process allows for precise control of the pulse arc. Accu-Pulse
provides optimum molten puddle control and has power to increase wire feed
speeds and deposition 20 to 25 percent in many applications. In most cases, slightly
different ratios of gas mixtures will perform well using a similar program and
adjusting arc length or the appropriate arc control for the selected process. Contact
Miller for more information on less common materials and gas combinations.

Accu-Curve
Accu-Curve™ is standard on all Auto-Axcess™ E models.
Accu-Curve is a variation of the Accu-Pulse process. The transitions from peaks
to background voltage are "curved". The curved transitions provide a "softer" feel

• Shorter arc lengths possible
• Better puddle control
• More tolerant of contact tip to work variation
• Less audible noise
• No arc wandering in tight corners
• Narrow arc plasma column
• Allows weld to fill in at toes increasing travel
• speed and deposition
• More tolerant of poor fit up and gaps
• (compared to standard pulse)
• Ideal for robot seam tracking applications
