Inverter based Multipurpose DC welder- CHAMP MULTI 400

The CHAMP MULTI-400 is a versatile, multi-process welding machine designed to handle various applications such as fabrication, pipe welding, and construction work. It supports MMA (SMAW), MIG/MAG (GMAW), and FCAW welding processes, making it suitable for welding mild steel (MS), stainless steel (SS), and aluminum using solid or flux-cored wires. Built with inverter-based technology, it incorporates advanced IGBT power modules, high-frequency transformers, and fast recovery diodes to ensure high efficiency and reliable performance even in demanding site conditions.In MMA mode, the CHAMP MULTI-400 supports all types of electrodes including CELWEL, which are commonly used for heavy-duty and industrial applications. The GMAW and FCAW modes allow semi-automatic and automatic welding with precise control, thanks to its single-point synergic control feature. The machine has both constant current (CC) and constant voltage (CV) output characteristics, making it flexible for different welding requirements.The welding system is equipped with multiple advanced features such as a digital front panel, remote controller, and adjustable parameters for crater voltage, crater current, arc force (MMA), and dynamic inductance (GMAW). It offers operating modes like 2T, 4T, SPOT, and Multi-Spot for enhanced control during MIG and FCAW operations. A unique pinch-off pulse function helps avoid globule formation during wire transfer, improving weld quality.To ensure safety and durability, the CHAMP MULTI-400 comes with several built-in protections. These include safeguards against over and under input supply voltage, single phasing, overheating of components, and output short circuits. It also features an auto "weld stop" when the torch is removed from the workpiece and an optional VRD (Voltage Reducing Device) for additional protection in SMAW mode. The equipment complies with the latest international standards, IEC EN 60974-1 and 60974-10.For easy troubleshooting, the machine displays digital error codes such as under-voltage (ERR 001), over-voltage (ERR 002), thermal trip (ERR 003), and others related to feeder and communication errors. Red LEDs indicate faults such as input voltage fluctuations or missing phases, and in any error state, the machine disables welding output to prevent damage.The complete CHAMP MULTI-400 system consists of the ICCCVR-401 power source, FEEDLITE 40 wire feeder, TW 402 or MTG 400 torch, optional gas pressure regulator, and CO? gas heater if required. With high efficiency over 85%, robust protection features, and user-friendly digital controls, the CHAMP MULTI-400 is a reliable and advanced welding solution for industrial and field applications.
