The CLOOS GL 222 DC is a portable inverter-based welding power source designed for both DC TIG and MMA welding, offering excellent welding characteristics and a user-friendly interface. This device is suitable for a wide range of applications, including workshop, food industry, hydraulics, oil pipelines, and chemical plants. Its compact and intuitive design, combined with high precision adjustments for all welding parameters, makes it a reliable choice for various welding tasks.
Function Description:
The GL 222 DC is a versatile welding machine capable of performing both TIG (Tungsten Inert Gas) and MMA (Manual Metal Arc) welding processes. It features an inverter-based power source, which ensures stable and precise control over the welding current. The machine is equipped with a comprehensive user interface that allows for easy selection and adjustment of welding parameters.
For TIG welding, the GL 222 DC supports various torch trigger modes, including 2T Lift-Arc, 2T HF, 4T Lift-Arc, 4T HF, Bi-level Lift, Bi-level HF, 2T Spot, 2T Spot HF, and Pilot Arc welding. These modes provide flexibility for different welding scenarios, allowing for precise control over arc initiation, current ramp-up/down, and gas post-flow. The machine also offers special functions for TIG welding, such as Q-Start, Dynamic Arc, and Multi-tack, which enhance performance and ease of use.
For MMA welding, the GL 222 DC provides stable arc characteristics and allows for adjustments of parameters like welding current, max welding current, hot-start, and arc-force. These features ensure optimal performance across different electrode types and welding positions.
The device includes several alarm management features to ensure safe and reliable operation. These include overheating alarm, cooling device alarm, and torch change-over alarm, which alert the user to potential issues and help prevent damage to the machine or the workpiece.
The GL 222 DC also incorporates job management features, allowing users to save and recall up to 50 personalized welding settings or jobs. This is particularly useful for repetitive tasks or for maintaining consistent quality across different projects.
