Multiquip DLW400ESA4 Welder/Generator

The Multiquip DLW400ESA4 is a high-performance CC/CV welder and generator engineered for demanding industrial, construction, and maintenance applications. Delivering up to 400 amps in single-operator mode or 200 amps per side in dual-operator mode, this unit offers exceptional flexibility and power. As a generator, it produces up to 14 kW of clean, stable 120/240V AC output, allowing operators to run tools and equipment while welding. Equipped with Smart Stick, E-Mode, and Arc Force Control, the DLW400ESA4 provides smooth, efficient, and precise performance, all powered by a Tier 4 Final Kubota diesel engine. Designed for low-noise operation and jobsite durability, this machine sets the standard for productivity and reliability.

FEATURES:

• Delivers up to 400 amps of welding power with the convenience of 14 kW of AC generator output
• Dual operator output capability for increased productivity and versatility
• Simultaneous AC power draw while welding for full operational efficiency
• Exceptional voltage regulation within ±1.5% ensures stable and reliable power delivery
• Powered by a Tier 4 Final Kubota D902 diesel engine for long-lasting, fuel-efficient performance
• Arc Force Control allows precise tuning of DC current to prevent electrode sticking during low-voltage welding conditions
• Provides smooth, consistent arc characteristics for superior weld penetration and quality
• E-Mode improves fuel efficiency by allowing one operator to weld up to 200 amps at idle speed Two operators can also use this feature when combined amperage does not exceed 200 amps
• Smart Stick automatically shuts the engine down during idle periods; tapping the welding rod restarts the unit instantly, ideal for elevated or hard-to-access welding applications
• Supports multiple welding processes including SMAW, FCAW, GMAW, GTAW, and ACAC
• Sound-attenuated cabinet reduces operating noise to 70 dBA @ 23 feet
• Full panel GFCI protection, OSHA and NEC compliant for jobsite safety
