An Engine Driven Welder is an autonomous device that generates electric current for arc welding and cutting. Such devices are often referred to as Mobile Engine Driven Welders because their design allows them to be transported by pickup truck or on a wheeled trailer.
The main components of a Mobile Engine Driven Welder include an internal combustion engine and an electric current generator. The generator converts the torque of a diesel or gasoline engine into electric current for welding.
Similar autonomous machines are usually equipped with auxiliary elements:
- An electric current generator to power electrical devices;
- A current control system;
- An idle voltage reduction unit;
*It is possible to additionally connect an electrode drying unit and air-plasma cutter, but by default, this is not available.
How is it used?
Mobile Welding Unit finds application in industries where welding is required without access to stationary power sources. Approximately 80% of such work takes place outdoors in harsh weather conditions, far from city utilities. For example:
- Repair and installation of urban heating networks, water supply systems, and other utilities;
- Laying and repairing gas pipelines and oil pipelines;
- Construction and repair of bridges;
- Shipbuilding and ship repair.
One distinctive feature of the design of Shindaiwa's Mobile Welding Unit is that during welding, electric tools can be connected to the working machines for additional and related work. Shindaiwa machines DGW400 are equipped with three 120/240V outlets and a 3-phase 15.0 kVA power connector. This allows supplying electrical power to a repair and installation crew without fluctuations in current.
The current generator in Shindaiwa units works with Simul Phase technology. The Simul Phase Generator allows simultaneous connection of 1-phase and 3-phase appliances and tools.
Thus, a Mobile Engine Driven Welder can serve as the basis for creating and operating an autonomous, versatile repair and installation team.
