Inverter Based DC Welder- CHAMP 400 X

The CHAMP 400 X from ADOR WELDING LIMITED is a rugged, reliable, and highly efficient DC welding machine designed to meet the needs of industrial-scale applications. Built on inverter-based technology, it offers smooth and stable welding performance across a wide range of operations. While primarily used for SMAW (Stick) welding, it can also be adapted for TIG welding using an optional external HF unit, adding to its versatility on the shop floor or job site.This machine stands out with its tropicalized design and zero-maintenance operation, making it ideal for demanding environments. The CHAMP 400 X is equipped with features like Arc Force and Hot Start adjustment for easy arc ignition and control, along with a built-in VRD (Voltage Reduction Device) for enhanced operator safety. With a VRD ON/OFF switch, users can manage output voltage levels in line with their safety protocols.The CHAMP 400 X is engineered for heavy-duty use, offering high efficiency and a high power factor. It complies with international safety standards (IEC 60974-1) and incorporates intelligent protections such as over-voltage, under-voltage, over-temperature, and single phasing—each with an auto-reset function for uninterrupted workflow. Despite its industrial capabilities, the unit is surprisingly lightweight and compact, ensuring easy handling and portability across workspaces.Technically, the machine operates on a 415V ±15% three-phase supply and delivers a welding current range of 10–400A DC. It provides 310A at 100% duty cycle and 400A at 60% duty cycle under standard ambient conditions (40°C). The open circuit voltage is maintained at 70V (±5V), and both the Arc Force and Hot Start can be adjusted from 0 to 100 for fine-tuned performance. It supports welding electrodes such as E6013 and E7018, in diameters from 2.5mm to 6.0mm.Additional features include forced air cooling, Class H insulation, IP23(S) ingress protection, and compatibility with an optional 10-meter remote controller for current setting. The CHAMP 400 X measures 580mm x 237mm x 440mm and weighs approximately 24 kg, striking an excellent balance between performance and portability.Backed by a one-year warranty from the date of commissioning, all CHAMP 400 X units are guaranteed to be free from manufacturing defects and fully compliant with the stated specifications. With a legacy of reliability and support, ADOR WELDING LIMITED ensures every product is delivered with peace of mind and ongoing customer care.
