    one that’s most appropriate for the application at hand, or for future appli- cations. For example, if the job calls for eight hours of welding day after day, an industrial-type wire feeder is most appropriate. These feeders typi- cally have more powerful motors, can run larger wire types and have more features than will a less costly and smaller wire feeder. While it’s important to note that these larger and more robust feeders may cost more upfront, they will generally pay for themselves over the long term.
Along with the right feeder require- ments, other key considerations include amperage and duty-cycle capa- bilities. Be sure that the power source and welding gun provide the required duty cycle and amperage for the job, and that they are compatible in terms of their amperage capacity. Portability of the wire feeder also might be an important consideration, depending on the application.
Next, it’s important to match the
interconnecting cables to ensure they are compatible with the available fea- tures of the wire feeder and power source. Some systems are digital, oth- ers analog; be sure to match the inter- connecting cable to the appropriate system type. This may require assis- tance from the equipment manufac- turer or distributor during the equip- ment-selection process.
Investing in a welding system may be a more expensive choice up front, but in many cases it can end up costing less in the long term, by eliminating downtime, improving quality and pre- venting lost productivity. Equipment manufacturers research and design welding systems to work together to enhance equipment features, increase productivity and ensure ease of use. For questions about the potential ben- efits of welding systems, or for help with selecting the right system for a given application, consult with a trust- ed welding distributor or equipment manufacturer.
