Power MIG
®
350MP power source:
Pulse-On-Pulse
on 3 mm Aluminum
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 reduces spatter and
improves bead appearance,
even for low voltage
procedures on stainless.
Power Mode aids bead
wetting and penetration
on aluminum.
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. The
result is improved MIG welding performance, including
low spatter, very uniform, consistent bead wetting and
controlled penetration. Power Mode benefits are especially
apparent on low voltage applications on thin steel and
stainless steel material less than 20 gauge (0.7 mm). It
also delivers excellent arc characteristics on aluminum
and other alloys such as silicon bronze and nickel alloys.

Pulsed MIG varies weld current between peak (high heat)
and background (low heat) current to provide better control of
heat input, which minimizes warping and burnthrough on thin
materials. Pulsed MIG also enables flat, horizontal, vertical up,
or overhead welding without a slag system. It can be used in
hard automation, robotic, and high production semiautomatic
applications. Optimized GMAW-P waveforms are readily avail-
able to use on aluminum, carbon steel, high strength low alloy
steel, stainless steel, and nickel alloys.

Synergic MIG
Synergic control of voltage and wire feed speed allows you
to set weld procedures with only one control for simplicity
and ease of use.
Set the wire feed speed and your voltage is automatically
set. Override the setting with the voltage/trim control for
personal preference.
1. Use one
knob to set
procedures.
2. Voltage is auto-
matically set.
