Pulsed MIG
• Varies weld current between peak (high heat) and background (low heat) current to provide
better control of heat input.
• Reduces warping and burnthrough on thin materials.
• Enables in-the-flat, horizontal, vertical up, or overhead welding without a slag system. Great for
hard automation, robotic, and high production semiautomatic applications.
• Optimized GMAW-P waveforms are available to use on aluminum, carbon steel, high strength
low alloy steel, stainless steel, and nickel alloys.

Pulse-On-Pulse
®
• Uses a sequence of varying pulse wave shapes to produce a TIG-like bead appearance and
excellent weld properties when MIG welding aluminum.
• Pulse-On-Pulse
®
controls arc length and heat input together, making it easier to achieve good
penetration.

Power Mode
®
• Uses high-speed regulation of output power to deliver extremely fast response to changes in the
arc, for example, when using a whip technique.
• Improved MIG welding performance, including low spatter, very uniform, consistent bead wetting
and controlled penetration.
• Great for low voltage applications on thin steel and stainless steel material less than 20 gauge
(0.7 mm).
• Delivers excellent arc characteristics on aluminum and other alloys such as silicon bronze and
nickel alloys.
