Magnum SNAKE 405 LED 400A 400V inverter welder
The Magnum SNAKE 405 LED is a professional inverter welder made for the heaviest industrial and structural work. Supplied from three phases (400V) and giving a strong welding current of 400A at a 60% duty cycle, it is a dependable tool for professionals. This model, built on the proven SNAKE series, carries a digital LED display and full control of the key arc parameters, so the welding process stays precise in ordinary workshop conditions, from bench work up to demanding assembly on site.
Key features

Three phase 400V supply for stability and output in industrial conditions
Full control of the process: adjustable ARC FORCE and HOT START
Added safety from the built in VRD function (Voltage Reduction Device)
Modern IGBT inverter technology for a stable arc and high efficiency
Legible digital LED display for setting the welding current precisely
Able to weld with every type of covered electrode, basic and cellulosic included
Technical details
Technology in detail
At the heart of the SNAKE 405 LED sits an advanced inverter board based on IGBT transistors. This technology gives high energy efficiency and a stable welding arc free of disturbance. The strong point of this model is full control over the arc character. The adjustable ARC FORCE function (arc dynamics) sets penetration depth and keeps the arc from dying away, which is needed when welding in difficult positions. The adjustable HOT START makes striking the arc easier by raising the current for a moment at the start, which counts above all with demanding electrodes. The VRD function (Voltage Reduction Device) is a safety system that lowers the open circuit voltage and cuts the risk of electric shock in damp surroundings.
Recommended applications
- Heavy industry and shipbuilding
- Steel structures and construction
- Assembly and repair work on site
- Welding pipelines and critical infrastructure
- Heavy production and repair shops
Control panel
The control panel of the SNAKE 405 LED was drawn up for simple operation and precision. Its central element is a large, legible digital LED display that shows the welding current setting without doubt. Current is set smoothly with a comfortable knob. Dedicated knobs for ARC FORCE and HOT START and a switch for the VRD system let the welder match the machine to the job in a moment, with no need to work through complicated menus.
