About this opportunity

The Department of the Army Materiel Command Mission and Installation Contracting Command Fort Drum is seeking to procure a 400 amp portable welder designed for mounting on a flatbed truck with a diesel engine. The welder must meet extensive technical specifications including an amperage range of 20-400 amps, capability to weld stainless steel and steel with rated carbon diameter of 3/16 inch, and DC current type with maximum open circuit voltage of 85 VDC. Key requirements include a Kubota engine with T4F compliance, minimum 20.2 horsepower, 11.5 gallon fuel tank, and specific operational speeds of 1500 RPM for idle and 1800 RPM for welding. The equipment must provide dual auxiliary power outputs of 10,000W continuous and 12,000W peak, maintain sound ratings of maximum 66 dB at idle and 71.6 dB while welding, and include dimensional constraints with maximum dimensions of 60 inches length, 28 inches width, 32 inches height, and 1000 pounds weight. The solicitation was posted on August 26, 2025, with responses due by September 8, 2025, providing a tight 13-day response window.

This procurement opportunity is designated as a Total Small Business set-aside under NAICS code 333992 for Welding and Soldering Equipment Manufacturing and PSC category 3431 for Electric Arc Welding Equipment. No incumbent contractors or potential award values are specified in the solicitation notice. The equipment must include a three-year warranty and specific features such as engine block heater and glow plugs for cold weather starting, eye lift capability for portability, and rated output specifications of 400A at 24V with 100% duty cycle minimum and 350A at 27V with 100% duty cycle minimum. Performance will take place at 1 C Tree Road, Building 4, in McAlester, Oklahoma 74501. The solicitation indicates procurement of a single unit based on the singular reference to "a 400 amp portable welder" rather than multiple units, suggesting this is likely a one-time equipment acquisition rather than a multi-year service contract.
