Tips for Buying Pre-Owned Robots
Buying a pre-owned industrial robot provides the opportunity to save significant money while still capitalizing on the benefits of robotic automation. Previously owned industrial robots are an excellent option for those who are budget conscious. The affordability of a pre-owned robot allows users to earn their ROI quickly. Pre-owned robots are also the best option for those with pre-existing robotic systems. Popular arc welding robots available on the second-hand market include the FANUC Arcmate 120ic and Yaskawa Motoman MA1440.
It is important when shopping for a pre-owned robot to be a conscious consumer. You want to make sure you are getting the best value for your money and a high-quality robot. Below is a list of tips to consider when going through the pre-owned robot buying process.
- • Buy from a reliable source - There is no shortage of pre-owned robot suppliers and the online marketplace has made it easier than ever to access used robots. Just as it is important to research the robot you are considering buying, it is equally as important to research who you are buying from. Only buy from reputable robotic equipment companies. A reputable company will test robots to ensure they are in working condition and will make facilitating shipping easier. It is best to avoid auctions both in person and online as there is often no guarantee you will get a working robot.
- • Verify application compatibility - Ideally before buying you should know what process you are automating. This will help you narrow down the articulated robot you will need. If you are automating a welding process, then a used FANUC Arcmate 100ic or ABB 2400L could work. Knowing the application will prevent you from buying the wrong robot or wasting your time looking at robots that will not work for you.
- • Verify robot specifications - It is also important to verify the robot specifications to ensure the robot will be able to fulfill the tasks being automated. These include payload, reach, axes, weight, and repeatability.
- • Verify robot hours - The seller should provide the hours on the pre-owned robot. These may include operation, running, and servo hours. Robot hours provide buyers with an idea of its operating history. However, high hour robots are still a good buy as robots can operate for over 100,000 hours.
- • Check the robot condition - You want to make sure you get the full picture of the condition of a pre-owned robot. If it is in good, fair, poor, or refurbished condition. The condition of the robot can affect the purchase price. As the buyer you want to ensure there are no surprises after the sale.
- • Check for missing parts - Sometimes sellers will list six axis robots with missing or damaged parts. Usually when this is the case the sales price is lower. As a buyer you should be aware if a robot will need repairs or replacement parts immediately.
- • Verify if the controller is the original - Older robots may have had their controller replaced at some point during their lifetime. When buying a pre-owned robot check to see if the controller matches and is the original. Robot hours are stored on the controller, so if the controller is a replacement the robot hours may not be accurate.
