Input power
Does your machine need to be self-powered, or will AC power
be available at the location where it’s primarily used?
For locations where an electrical hookup is not practical,
• consider
a diesel-powered engine-driven welder/generator
Output power
Light industrial products are suitable for the hobbyist or
occasional light industrial user. They are designed to be easy
to operate, are affordably priced and typically have a low duty
cycle and lower-rated output.
Industrial products are suitable for applications that do not
require high-volume production. They typically have a 60 percent
duty cycle and/or rated output of 300 amps. Industrial products
are an appropriate choice for professional welders.
Heavy industrial products are suited to high-volume
production and/or welding of thicker materials. They typically
have a duty cycle of 60 to 100 percent and a rated output of
at least 300 amps. Heavy industrial products are designed
with the arc characteristics and product features professional
welders demand for code-quality work.
Note: Units listed in more than one classification share attributes of both.
Portability
Can you bring the work to the machine, or does the machine
need to go to the work? Check the Product Guide pages for
types of portability:
• Shoulder strap, handles, running gear, carts, etc.
engine-driven welding generators fit in the back of a truck,
• Many
enabling them to be driven to wherever the welding is needed.
Heavy-duty trailers are also available for engine drives.

you’re considering:
Out in the field, you may need an engine-driven welder/generator
to supply AC power to run tools and lights, or supply 12-volt
DC power to charge automotive batteries and jump-start
vehicles. Miller®welder/generators are packed with power;
larger units even offer option packages that add 10 to 20 kW
of generator power.

About duty cycles
Duty cycle is an indication of how long a power source
can continuously weld (at a specific amperage and voltage)
in a 10-minute period of time before it needs to cool down.
For example, a machine with a 60 percent duty cycle at
300 amps and 32 volts of welding output can be used
(at 300 amps and 32 volts) for 6 minutes out of a 10-minute
period. When comparing two similar-sized power supplies it
is important to pay close attention to both the amperage
and voltage values that determine the rated load.

Processes
Manual mode allows for simple manual setting of parameters for
welding on a broad range of applications.
Thermal overload protection shuts down the power source output if
the main transformer or rectifier overheats.
Industrial dual-gear-driven system features a no-tool, quick-change
reversible drive roll (0.8/1.0 mm) and an easy-to-set tension
adjustment knob.
Traditional tapped design and laminated inductor provide a stable,
smooth arc for consistent weld quality.
