Auto-Set™: The right settings automatically —
• Set the wire diameter, a blue light shows
that Auto-Set ™ is activated
• Dial in the thickness of what you’re welding
• Start welding with the exact parameters
you need!
Infinite voltage control gives you the
flexibility to manually set the machine
when welding aluminum, stainless steel,
or anytime you want to set your own
parameters on mild steel.
Smooth-Start ™ patented technology
provides a smooth, spatter-free start.
It’s the best-starting machine in the
small MIG machine category. No pop
gun starts and no spatter to clean up.
Comes Complete With:
Power source
6 ft (1.8 m) power cord and plug
10 ft (3 m), M-10 MIG gun and cable assembly
10 ft (3 m) work cable and clamp
Smith® Argon and AR/CO2 mix regulator/flow
gauge with hose
Spool of Hobart® .030 in (0.8 mm) solid wire
Two contact tips for .024 in (0.6 mm) wire and
two contact tips for .030 in (0.8 mm) wire
Dual groove quick-change drive roll for .024 in
(0.6 mm) or .030/.035 in (0.8/0.9 mm) wire
Factory-installed gas
solenoid valve

Material thickness gauge ➤
#229 895
Note: Shielding gas and safety
equipment not included.
Durable cast aluminum drive system
incorporates dual-groove quick-change
drive roll and spring-loaded tension arm
with calibrated tension knob, all designed
to make set up easier and faster.
Easy access to output studs
provides convenient polarity
changeover when changing
from solid or flux cored wires.
Thermal overload protection
shuts down unit and activates
over temperature light if airflow is
blocked or duty cycle is exceeded.
Automatically resets when fault is
corrected and unit cools.
Semiautomatic constant voltage
wire welding package is capable
of welding 24 gauge up to 3/16 in
(0.8 – 4.8 mm) mild steel.
Standard built-in solid-state
contactor circuit makes wire
electrically “cold” until trigger is
pulled, making the unit safer.
It’s also easier to position torch
to work before starting weld.
Miller’s exclusive “Tip Saver” short
circuit protection shuts down output
when tip is shorted to the work.
Extends contact tip life and protects
internal components from damage.
Trigger reset permits quick reset at
torch rather than unit.
Uses 4 or 8 in (102 or 203 mm)
spools and can be set up to weld with
wire sizes .024–.030 in (0.6–0.8 mm)
mild/stainless steel and .030 –.035 in
(0.8 – 0.9 mm) flux cored.
Self-resetting motor protection
circuit eliminates the need to find
and replace fuses.
Welder is warranted for 3 years, parts and labor. Original
main power rectified parts are warranted for 5 years.
Gun warranted for 90 days, parts and labor.

Auto-Set Feature
™
The Millermatic® 140 Auto-Set™ offers all the
benefits of the standard Millermatic 140, but
adds Auto-Set to eliminate the guesswork.
Auto-Set Mode
• Turn wire speed control fully clockwise to
select Auto-Set mode. Set the wire diameter
to either .024 or .030 in.
Use Auto-Set when you want the speed,
convenience and confidence of pre-set controls.
Simply set the wire diameter, set the material
thickness, and go! The Auto-Set control
automatically sets your welder to the proper
parameters. It is available when welding mild
steel with solid wire and only works with .024
and .030 solid wires and C25 shielding gas
(75% Argon, 25% CO2).
• Light indicates Auto-Set mode is activated.
• Set the material thickness within Auto-Set
range for 24 gauge through 3/16 in mild steel.
The welder automatically sets itself to proper
parameters, and is ready to weld!
When not within the Auto-Set profiles, use the
manual mode to set the weld parameters you
desire. The parameter door chart lists voltage
and wire feed speed settings options.
