What ENTRON Controls does
ENTRON Controls, LLC is a privately held US manufacturer of microprocessor-based solid state resistance welding controls, headquartered in Greer, South Carolina and founded in the early 1970s. The company designs and builds a broad portfolio of welding controllers across three technology families — MFDC (Medium Frequency Direct Current) inverters (including the iPAK2v2 family supporting up to 300 kA weld current and up to 8 transformers), single phase constant current AC controls (EN6001, EN7000, WS500 series), and a deep installed base of legacy controls (EN1000/2000 series, WS2003, WS4000, Microstar 700, IPSC System) — complemented by accessories such as the Hi5 Weld Monitor (five-variable millisecond-interval process monitoring), H5 Heat Controller, WA2 Weld Analyzer, and Welder Interlock. The portfolio supports spot, seam, projection, flash/butt, and crosswire welding with programmable schedules, multiple weld intervals, and cascade/multivalve operation, integrating with industrial automation environments via Profibus, DeviceNet, EtherNet/IP, Modbus-TCP/RTU, ControlNet, InterBus, Ethernet, USB, and 4G.
The company operates through a wholly-owned UK subsidiary (BF Entron Ltd., acquired in 2002 and headquartered in Dudley, England) and a Mexican manufacturing joint venture (ENTRON de México S.A. de C.V., established in 2015 in Saltillo, Coahuila), giving it a three-country manufacturing and service footprint spanning North America and Europe. Revenue is generated through quote-based hardware sales of welding control systems, custom configurations, spare parts, and ancillary repair and training services — pricing is not publicly disclosed. The go-to-market model is a regional field sales organization with Technical Sales Consultants, Territory Sales Managers, an Inside Sales Representative, and a Mexican country manager covering USA, Canada, Mexico, UK, EU, and Rest of World.
Customer concentration is heavily skewed to the automotive sector, with explicit named relationships with Chrysler, Ford, GM, Jaguar, and BMW/Mini plus their global Tier 1 suppliers (via BF Entron heritage), and supplemental exposure to industrial welding (drums, barrels, coil joining, military/aerospace) and consumer goods (appliances, hot water tanks, battery tabs). The company is ISO 9001:2015 certified across both US and UK operating entities and maintains technical documentation, software downloads (NetFlash PC Software, ENLINK), and a YouTube channel for customer education.
