Why do PM on Generators?
A PM program is the best way to see many issues before they take your unit out of service. This is where most of the problems are found & corrected.
How often should my equipment have this type of service?
That depends on two things, 1st how often you are running the equipment and is it safe. Weld Power will quote your needs and cover all the needed service schedules.
What’s included in the PM agreement?
Weld Powers comprehensive PM agreements include the factor recommended Oil & filter changes as well as the needed inspections. Oil & coolant samples are taken at the time of the PM and the results reported back to you.
Why do you sample the oil & coolant?
This very important step is required to help keep your engine running at its peak performance. The information gathered from our lab tells the story of engine wear, coolant protection levels, and the start of the internal engine and radiator issues before they become a catastrophic failure.
What else is included in your PM program?
The inspection of all the major components related to your emergency power system. This includes the engine, radiator, battery & starter, alternator, engine controls, safeties, shutdowns, fuel systems, and air movement around your generator.
What is done with the information you gather from the PM report?
The Tech that does the PM inspection will fill out the proper report electronically and send it to the office. Once we obtain all the data and get back your oil & coolant sample you will receive a copy of all the documents for your records.
What happens if something out of the ordinary is found during the inspection?
The Tech on-site will bring it to your attention ASAP and he will also report the finding to the office. We will discuss the options of a repair while we are on-site or quote to repair at a later date depending on the repair needed.
My generator will not start during the PM, now what do we do?
Our Tech on-site will look into the problem and see if it’s something simple that can be repaired while we are on-site or if more troubleshooting will be needed.
How are my batteries tested?
The batteries are one of the most important items that need to be checked and tested. We use a meter attached to the battery and then check for voltage drop during the crank cycle. If the voltage drops below manufacture standards or the battery is more than 24-36 months old (Based on application) we will recommend changing them.
How often should a generator be serviced?
At a minimum, a generator should be serviced by a professional at least once a year and the oil & filters changed during that time. However, Weld Power recommends that a generator be checked semi-annually or quarterly in order to ensure the generator is being properly maintained and to be able to identify any issues prior to failure.
What do you do to “service” a generator?
All of our technicians perform a “22 point inspection” on the unit at each visit.
How often should a generator be run?
It is recommended that a generator be run weekly to ensure that it not only starts but to ensure all mechanical parts stay properly lubed and functional. Most generators are set up with a built-in exercise clock to automatically run the generator weekly. If your generator is not set up to exercise weekly, call us at 1-800-288-6016 and we can ensure that it does.
How often should the batteries be changed in a generator?
It is recommended that batteries be changed every 24-30 months to ensure proper reliability.
How will I know that the generator has been serviced?
All of our technicians are equipped with iPads and fill out all records/paperwork from the service visit electronically, fully documenting what was performed. These service reports are then emailed to the address that we have on file.
How do I know when my generator is scheduled to be serviced?
Depending on the type of service plan that you are enrolled in, a member of our service department will contact you when the scheduled month of service is near. An appointment will be set for the generator to be serviced.
Your technician made a list of recommended repairs on their report. Do I have to do them?
Our technicians are required to report any issue that they see during a service that could potentially lead to a failure. It is our responsibility to report our findings and make the customer aware of any potential issues. Everything reported is in the best interest of the piece of equipment being serviced but ultimately it’s the customer’s decision on whether to follow our recommendations.
What’s the difference between a Major Maintenance and a Minor Check?
Both services include our “22 point inspection” however during Major Maintenance the oil, oil filter(s) & Fuel Filters (if applicable) are replaced.
There is an alarm on my generator, what should I do?
You should call our 24/7 Emergency Response line (1-800-288-6016) and we will dispatch a technician to investigate. We are available 24 hours a day 7 days a week to respond to your needs.
Weld Power services our generator but I can’t find my last service report, do you keep copies?
Weld Power keeps records of every piece of equipment we service for our customers. If you need a copy of a past service record, you can call our office and we will send you a copy.
Do you service all makes & models?
Weld Power’s technician fleet is factory authorized and certified for all makes and models of generators.
What is the cost of a generator planned preventative maintenance program?
Pricing varies per generator. The equipment’s specs are needed to price out the PM such as generator make, model, and kW size. Engine make, model # are also needed and appreciated to be able to confirm the necessary materials to replace during the inspection visit.
What kind of reporting do we receive?
Our customers receive real-time documentation of our service call inspections. Weld Power created an IPad application to create a one of a kind back-up power equipment reports. We interviewed hundreds of directors of operations, facility managers, and property managers and received feedback on what is appreciated and needed on these forms and we implemented it. We have been receiving phenomenal feedback on how well they suit individual site needs but most importantly the group regional contract needs. The easy readability along with the photographic evidence has made a really profound statement in the region. Our regional technician fleet is equipped with IPads, laptops, and printers in their fully stocked vans.
What is an ATS?
Automatic Transfer Switch. This mechanism is installed to transfer power from the normal source to the emergency source and then back again automatically with no need for any human interaction. This equipment is vital for the proper operation to follow any interruption of power.
How often should the Transfer Switch be tested & Preventative Maintenance performed?
Based on the application the test should be tested once a month and a PM performed once a year.
What’s included in the Transfer Switch Preventative Maintenance?
The Transfer Switch Preventative Maintenance includes the visual inspection of all components, the testing of the contactor, testing the relays & controls, Torque all lugs to factor specs, clean & lube of all moving parts, and full reporting & documentation of the findings.
Will the power need to be turned off during the Preventative Maintenance?
Yes, the best and most effective way to do proper Preventative Maintenance is to have the circuit to the Automatic Transfer Switch de-energized during the Preventative Maintenance. This will also mean taking the generator offline during the procedure.
Once the power is turned back on what will happen?
The Tech will test the ATS to make sure it transfers to emergency and back to normal as per spec. The generator will then be left in automatic and ready for service.
What will happen if the Transfer Switch does not work during the Preventative Maintenance inspection?

The Transfer Switch is deemed out of service, now what do we do?
Weld Power can install a temp Transfer Switch to keep you up and running while your Transfer Switch is repaired or replaced.
Our generator is working fine, why are we having Transfer Switch issues?
While the Transfer Switch & generator need to both be working together they are two separate pieces of equipment and work independently of each other. This is the reason for the PM on both pieces of equipment.
What happens after the Preventative Maintenance is completed?
Once the Preventative Maintenace is completed and the generator is back in automatic the Tech on-site will send in his report electronically to the office. Once the report has been gone over by the office staff you will receive a copy for your record.
What if items are noted in the report that needs to be addressed?
Weld Power will send you a quote for any needed repairs that could not be completed while we were on site.
Do you service all makes & models?
Weld Power’s technician fleet is factory authorized and certified for all makes and models of transfer switches.
What is the cost of a transfer switch maintenance program?
The cost of the transfer switch program does not vary per transfer switch manufacturer, but per the scope of work. We have basic planned maintenance programs for extremely robust transfer switch maintenance programs. The pricing will vary based on the time of the test as well: normal hours vs. off-hours.
What kind of reporting do we receive?
Our customers receive real-time documentation of our service call inspections. Weld Power created an IPad application to create a one of a kind back-up power equipment reports. We interviewed hundreds of directors of operations, facility managers, and property managers and received feedback on what is appreciated and needed on these forms and we implemented it.

During a Transfer Switch Preventative Maintenance, will I lose power to the building?
For the maintenance itself, it does not require powering down the building, however, there is a part of the maintenance that does require switching the contactor from the Normal to the Emergency position which will result in a slight interruption in power to the building which may affect computers or any sensitive electronic equipment on the Emergency circuit.
I can’t afford any interruption in power to the building during normal working hours; can this test be performed after-hours or late at night?
Yes. We service numerous critical care sites that cannot afford to interrupt daily operations. If testing needs to be performed after hours, we can accommodate
What is the purpose of testing the Transfer Switch?
The Transfer Switch is a critical piece of emergency equipment that first senses a loss of utility power and calls for the generator to start. By testing the Transfer Switch you are ensuring that it is functioning as designed and will operate in the event of a power outage.
If there is a fault light indicated on the Transfer Switch, should I open the door to investigate?
It’s not recommended that anyone other than a trained professional touch the Transfer Switch. This is a live piece of electric equipment and could result in serious injury if safety precautions are not followed. It’s best to call us at 1-800-288-6016 and we will dispatch a technician to your facility.
What if it is determined that the Transfer Switch is in need of repairs?
Depending on the make, model, and age of the Transfer Switch, most can be easily repaired. If the Transfer Switch is in need of major repair, we offer rental transfer switches that can be installed while your existing Transfer Switch is being repaired to ensure that your building has emergency coverage in the event of a power loss.
What if parts are obsolete for my particular Transfer Switch?
If parts are no longer available and your Transfer Switch is in need of repair, you would likely need to upgrade to a new model Transfer Switch. We have experienced technicians who have performed numerous in-field upgrades of Transfer Switch’.
I have an older Transfer Switch and am looking to upgrade to a new model, what information do I need to know in order to get a quote for an upgrade?
It is best to know the current, make, model, voltage, amperage, and phase of your current Transfer Switch. All of this information can likely be found on the equipment data tag. At the bare minimum, you should know the amperage, voltage, and phase of the ATS and our sales team can match up a comparable Transfer Switch for you.
I am unsure what this Automatic Transfer Switch controls, is there a way to find out?
Yes. Weld Power can assist in determining what circuits are currently on the emergency side of the ATS. This will require shutting down power to the building and will require the assistance of an on-site electrician. Contact our office for more information.
There’s a humming noise coming from the Transfer Switch, is this normal?
This is called “chattering” and could be a sign that the relays inside the Transfer Switch are starting to fail. If you notice a humming sound coming from the ATS you should call our office and we will dispatch a technician to investigate.
