TIG 250DE
TIG/MMA Welder
- Built with RILAND self-developed RICHIP control chip and the latest high-end IGBT inverter technology.
- Wide input voltage range of 220V ±15% for better adaptability to site power conditions.
- Segmented display allows clear welding parameter viewing and adjustment.
- Supports HF TIG and MMA stick welding.
- In MMA mode, VRD, adjustable arc force, and anti-stick functions help improve safety and operating control.
- In TIG mode, adjustable post-flow gas time supports better tungsten protection, with an arc ignition success rate up to 99%.
- Built-in overvoltage, overload, and overheating protection.
- Intelligent fan control runs only when needed, helping reduce noise and internal dust buildup.
- Standby mode, power factor above 0.7, and overall efficiency above 75% support more energy-efficient operation.
- Compact 3.3 kg power source with 304 × 117 × 175 mm dimensions and an adjustable shoulder strap for portable welding in elevated, outdoor, and confined work areas.
