A welding unit is a standalone installation that combines a power generator and a welding machine (welding station). The generator within the welding unit generates electrical current for welding and cutting through arc welding. The welding station (or two stations) ensures the welding process, control, and monitoring of the welding. Such equipment, also known as mobile welding units, is designed to be easily transported by motor vehicles or wheeled trailers.
These devices enable the execution of various types of welding. For instance, the DGW400DMK Shindaiwa unit can be utilized for the following types of welding:
- MMA (manual arc welding);
- MIG/MAG (semi-automatic);
- FCAW (semi-automatic with flux-cored wire)
- GOUGE (arc gouging and cutting)
Where use Mobile Welding Units
Mobile welding machines are used in industries where welding is required but there is no access to fixed power grids. Examples include:
- laying and repairing gas and oil pipelines;
- shipbuilding and ship repair;
- bridge construction and repair;
- maintenance and installation of municipal utilities.
Mobile welding units powered by diesel fuel are suitable for prolonged continuous operation. Diesel units differ from gasoline models in moderate fuel consumption, lower engine RPM, enhanced durability, and the ability to operate for extended periods without overloading.
Usually, self-contained diesel units are equipped with auxiliary elements necessary for convenient operation. For example:
- current control system;
- idle voltage reduction unit;
- a power generator for powering electrical appliances;
- devices for air-plasma cutting;
- remote control;
- special connector for connection of the welding wire feeder;
- displays and signal lamps for monitoring welding parameters.
Diesel welding units are easy to maintain and more resilient to harsh environmental conditions, which makes them the preferred choice for those who value quality, reliability, time, and efficiency.
