MOSA TS-405-EVO-MULTI4 Welder & Generator

The Mosa TS 405 EVO Multi4 is an Diesel KOHLER KDW1003 Engine Driven Welder with a Water cooled three-phase asynchronous Alternator. This combines powerful diesel-driven welding with versatile multi-phase AC power generation in a durable, field-ready package. Designed for professionals requiring high-performance welding and auxiliary power, it’s ideal for construction, shipbuilding, maintenance, and remote site operations.

Key Features & Benefits

• Powerful 400 A DC welding output with 60% duty cycle (330 A @ 60%) and extended capacity up to 300 A @ 100%—perfect for Stick and TIG processes

• EVO MULTI4 CONTROL

  Is the new panel for engine driven welders by MOSA, created with the purpose of giving to the user a complete new experience in which it is possible to control each parameter of the welding:

  • Customized programs
  • Voltage control
  • Current control
  • Arc force setting
  • Slope of the starting/stop current TIG
  • Switching frequency for pulsed Tig
  • PRE-SETTING
  • HOT START
  • LIFT ARC TIG
• Engine protection lovato:
  The Lovato RGK420SA control unit has an ignition key and push buttons for controlling the engine. A wide LCD display allows the visualization of alarms and the monitoring of machine parameters. The main features are:
  • User interface with symbols, codes and texts.
  • Setpoints adjustable via controller buttons or PC
  • Remote Start and Stop
  • Configurable inputs and outputs
  • NFC interface for wireless programming

• Multi-phase auxiliary power outputs: 14 kVA three-phase (400 V), 8 kVA single-phase (230 V), and 4 kVA (110 V), all available during welding operations

• Long runtime & fuel efficiency thanks to a 38 L diesel tank, ensuring 11.5 hours of continuous welding at full load

• Highly durable design: Stage V compliant Kohler engine (KDW1003), IP23 canopy, bunded base, engine/play service access for straightforward maintenance

• Robust features including VRD for operator safety, emergency stop, fuel level sensor, oil/water drains, central lifting eye, and audible overload warning

• Field-grade mobility with fork pockets, optional wheel or trailer kit, and reinforced chassis—all “Made in Italy” quality.
