A&A Equipment & Supply Co. Is Now Miller Certified

Certified Independent Repair Center for Miller Gas and Electric Welders

If your welding equipment is down, the job is down. That’s why A&A Equipment & Supply Co. is proud to announce we’re now Miller Certified—a true, certified independent repair center for Miller equipment. We provide warranty and out-of-warranty repairs on both:

• Electric welders / power sources (inverter and transformer-based)

• Engine-driven welders / generators (gas and diesel engine drives)

Whether you’re a contractor, fabricator, fleet manager, or maintenance team, you now have a local, reliable place to get your Miller equipment diagnosed and repaired correctly—without guesswork.

What Does “Miller Certified” Mean for You?

Certification isn’t just a badge—it’s a standard.

When you bring your machine to A&A, you’re working with a shop that’s set up to service Miller equipment properly, with the right process, tooling, and documentation. That leads to:

• More accurate diagnostics

• Faster turnaround times

• Repairs done to spec

• Clear communication and paperwork

• Confidence in the result—especially on higher-dollar units

Electric Welders (Shop, Field, and Truck Setups)

We service common issues like:

• No output / intermittent output

• Fault codes and control issues

• Feeding and arc stability complaints

• Connector, cable, and internal component failures

• Performance troubleshooting and functional testing

If your welder is “acting weird,” cutting out, or not welding like it used to—bring it in. The earlier you diagnose, the cheaper it usually is.

Engine Drives

Engine drives are workhorses, but they get abused: dust, vibration, weather, rough transport, long hours, and inconsistent maintenance. We can help with:

• Full engine rebuilds

• No-start conditions

• Charging / power generation issues

• Output and welding performance problems

• Engine-related service and troubleshooting

• Generator and weld circuitry issues

If it’s a Miller engine drive, we can handle it—warranty or not.

Warranty Repairs and Out-of-Warranty Repairs

Warranty Service

If your equipment is still covered, we can perform warranty repairs as a certified service center—so you don’t waste time chasing the right channel or shipping a unit far away.

Out-of-Warranty Service

If your machine is older or outside coverage, we’ll give you a straightforward repair path:

• Diagnostic evaluation

• Clear estimate

• Repair options based on cost/benefit (especially on older units)

• Quality repair you can rely on

Why Contractors Choose a Certified Independent Repair Center

You don’t just need “a repair.” You need:

• Correct diagnosis the first time

• Parts and repair decisions that make sense

• A team that understands your schedule and downtime cost

• A repair shop that works on equipment every day—not occasionally

A certified independent repair center is built for repeatable results, not guesswork.

What to Expect When You Bring Equipment to A&A

We keep it simple and professional:

1. Drop off your unit (or call ahead with model/serial details)

2. Diagnostic evaluation

3. Estimate + recommended path forward

4. Repair + testing

5. Pickup ready to work

If you’re running crews, we can also help you set up a practical plan for preventive maintenance and service intervals—especially for engine drives that see heavy seasonal usage.
