Multiquip DAW500SA4 Welder Generator 500A 3KW 120 through 240V

Multiquip DAW500SA4 Welder Generator

The Multiquip DAW500SA4 is a high-capacity, industrial-grade welder-generator designed for the heaviest structural applications. Powered by a liquid-cooled Kubota Tier 4 Final diesel engine, it delivers a massive 500-amp DC output, providing the raw power required for heavy-duty Stick welding and high-volume Carbon Arc Gouging (ACAC)

Features: 

500 amp DC output & 3 kW AC

• Engineered for maximum utility on large-scale builds, the DAW500SA4 provides the raw strength of 500 amps of DC current alongside a versatile 3,000-watt AC generator, ensuring you have both the arc for heavy-duty carbon cutting and the power for peripheral equipment

CC and CV welding capabilities

• Maximize your equipment ROI with dual CC/CV functionality; this advanced power management system provides the stable current needed for critical Stick welding and the precise voltage control required for high-speed wire welding.

Voltage regulation is maintained at ±10%

• Built for the rigors of the construction site, the generator maintains a consistent $\pm$10% voltage regulation, providing the stable electrical flow necessary to keep heavy-duty industrial tools and lighting systems running smoothly

Showcases a clean burning Tier 4 final EPA-approved Kubota diesel engine 

• Equipped with a legendary Kubota liquid-cooled powertrain, this machine features advanced clean-burning technology that ensures full environmental compliance without sacrificing the high-torque performance required for 500-amp welding.

Electric-start, Lifting bail, external oil/fuel drains come as standard features

• Engineered for convenience in the field, this model features a standard electric-start and an industrial hoist-ready lifting bale for easy maneuverability. Maintenance is simplified through external fluid drains, ensuring your oil and fuel changes are fast, clean, and efficient

SMAW, FCAW, GMAW, GTAW and ACAC welding processes

• Maximize your operational capacity with a true multi-process power source; whether you need precision TIG beads or the raw force required for 500-amp Carbon Arc Cutting, this machine handles all major welding processes with professional-grade stability.

Sound attenuated cabinet reduces noise output to 74 dBA @ 23'

• Minimize jobsite noise pollution without sacrificing performance; the fully enclosed, vibration-dampened housing suppresses mechanical roar to a manageable 74 dB(A) at 23 feet, making it ideal for large-scale construction in urban areas

Full panel GFCI protection - OSHA and NEC compliant

• Prioritize operator security with integrated, system-wide GFCI circuitry; this unit delivers 100% code-compliant auxiliary power that meets all OSHA and NEC requirements for heavy industrial welding environments

Options - Wire remotes, welding cable, cable carriers, tool box and trailers are available for this model.

• Convert your unit into a fully mobile repair center with available factory options; choose from custom-fit highway trailers and cable carriers for maximum portability, or add secure storage solutions to keep your specialized gouging and welding gear organized
