400 Amp Welding Machine Kw

The 400 amp welding machine (kilowatt class) is built for heavy-duty welding, easily handling ultra-thick steel plates with strong weld penetration and high strength. This 400 amp welding machine (kilowatt class) supports multiple welding modes-ideal for thick plate splicing, root pass welding, and filler welding-eliminating the need for multiple devices. Whether you're working on ship hulls or heavy machinery, the 400 amp welding machine kw delivers the power and versatility required for heavy industry.

With a power output of 30 kW or more and a 50-400 amp current range, the 400 amp welding machine kw welds 3.0-12.0 mm thick steel plates, compatible with 4.0-8.0 mm welding rods and 1.2-1.6 mm welding wire. It operates on 380V three-phase power with an IP23 protection rating, and the heavy-duty all-steel shell with shock-absorbing feet ensures dust and splash resistance. Imported core components, redundant circuit design, and intelligent temperature control (high-power fan + large-area heat sink) guarantee long-term reliability.

Equipped with overvoltage, overcurrent, overheat, and electric shock protection, the 400 amp welding machine kw supports remote control for convenient operation. Its multi-mode adaptability meets diverse heavy-industry needs, and the ability to operate at full load for extended periods ensures productivity. Low maintenance costs and durability make this 400 amp welding machine (kilowatt class) perfect for heavy machinery manufacturing, large steel structures, shipbuilding, and pressure vessel processing-from shipyard hull welding to machinery plant heavy equipment fabrication.
