400A IGBT TIG MMA Pulse Welding Machine with Water Cooling – Multi-Process Inverter Welder

Product Overview

This full-digital inverter welding machine is a high-performance multi-process power source engineered for both professional fabrication shops and on-site mobile work. Built around high-power IGBT modules and full digital MCU control, it delivers exceptional arc stability, energy efficiency, and welding quality — making it an ideal upgrade from bulky conventional industrial welders.

Key Features

High-power IGBT inverter technology – high reliability and high working efficiency in a compact, lightweight body.
Multi-process versatility – dual TIG welding and MMA (stick) welding functions, plus carbon arc gouging, offering outstanding cost performance.
Full digital MCU control – pre-gas, arc-start current, ramp-up time, peak current, base current, pulse frequency, duty cycle, ramp-down time, crater current and post-gas time are all precisely adjustable.
High-speed pulse waveform output – excellent arc stiffness, minimal heat-affected zone and ideal fish-scale seams, perfect for ultra-thin-plate welding.
Optional water-cooling system – enables long-time continuous operation; integrated power-supply / water-tank / trolley design can also carry a gas cylinder for mobile operation.
Patented intelligent protection – against overvoltage, undervoltage and phase loss, safeguarding the machine from unstable power grids.
Wireless remote control – communication-band full-function remote controller supports convenient long-distance operation.
Duty-cycle performance – continuous load operation for 6 minutes at 40°C; compact design eliminates the bulk of traditional welders.
Energy-saving – complies with Grade 1 energy-efficiency standard GB 28736-2019.
High efficiency – 100% arc-striking success rate and superior pulse welding performance.
Eco-friendly – low high-frequency interference, no disturbance to peripheral equipment or welding robots.
Intelligent & connected – compatible with mainstream welding robots of various brands; upgradeable to an IoT welder for network-based group control and management.
Communication – supports analog IO and RS485 communication.
