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.

Check out the Product Guides.

The Product Guides (at the start of each major section) briefly

describe and compare power sources within that section.

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.
