Quick and easy setup
Auto-Set ™ automatically provides the right
settings to weld mild steel while infinite voltage
control allows the flexibility to manually set
your own parameters.
• Set the wire diameter, a blue light shows
Auto-Set is activated
• Dial in the thickness of what you’re welding
• Start welding with the exact parameters
you need!
Angled cast-aluminum drive system with
calibrated tension knob creates consistent feeding
and easy setup for up to 15-foot MIG guns.
Quick Select drive roll makes setup quicker
by offering three grooves — two for different
size solid wire and a third for flux-cored wire.
™
Auto Spoolgun Detect™ automatically detects
when a MIG gun or spool gun is connected
eliminating the need for a switch.
Smooth-Start ™ provides a smooth, spatter-free
start. It’s the best-starting machine in the small
MIG machine category.
Thermal overload protection shuts down unit
and activates the over temperature light if
airflow is blocked or duty cycle is exceeded.
Automatically resets when unit cools.
Uses 4- or 8-inch (102 or 203 mm) spools
and can be set up to weld with .024 –.030 inch
(0.6 – 0.8 mm) solid wire and .030 –.035 inch
(0.8 – 0.9 mm) flux-cored wire.
Comes complete with:

Use Auto-Set when you want the speed, convenience and confidence of pre-set controls.
Auto-Set automatically sets your welder to the proper parameters. It’s available for welding
24-gauge through 3/16-inch mild steel, and only works with .024 and .030 solid wires and
C25 shielding gas (75% Argon, 25% CO2).

Auto-Set eliminates guesswork and saves you time on setup. Turn wire speed control fully
clockwise to select Auto-Set mode, and set the wire diameter to either .024 or .030 in.
The Auto-Set light indicates mode is activated. Then select material thickness using the
Auto-Set control.

When welding outside of Auto-Set’s
capabilities, or if you prefer custom
parameters, use manual mode. The
parameter chart on the inside of the
access door is an easy-to-use guide
for determining your voltage and wire
feed speed settings. Reference the
white areas on the controls when
welding in manual mode.
