Magnum MIG 501-S WDP15 LCD MIG/MAG welder
The Magnum MIG 501-S WDP15 LCD is a powerful industrial welding power source designed for the heaviest tasks in production plants and in heavy industry. Its modular design, with a separate four roll wire feeder and an efficient liquid cooling unit, together with a welding current of 500A and advanced functions such as double pulse, makes it an uncompromising tool for high output welding of thick steel and aluminium structures.
Key features
Industrial power of 500A at a high duty cycle of 60%
Modular build with a separate wire feeder and an integrated liquid cooling unit
Advanced functions: full synergy, pulse and double pulse (Dual Puls)
Professional four roll wire feeder (4×4) for stable feeding
Ideal for welding stainless steel and aluminium with the weld appearance of TIG
Three phase 400V supply for stable operation at full power
Built for continuous work on production lines and in hard conditions
Technical details
A look at the technology
At the heart of the machine is synergic microprocessor control, which selects the welding parameters automatically once the material, the wire and the gas have been chosen. The key technology is double pulse (Dual Puls), which modulates the current and the pulse frequency and gives a perfectly even weld with a "scale" appearance, comparable with the TIG method, while keeping MIG/MAG productivity. The integrated liquid cooling unit keeps the welding torch at the right temperature during long work at maximum power, which is essential in industrial use.
Recommended applications
- Heavy industry, shipyards, production of agricultural machinery
- High output production and welding lines
- Welding of thick steel, aluminium and stainless structures
- Reconditioning and hardfacing of machine parts
- Professional metalwork and structural workshops
Control panel
The machine has an advanced control panel with a large, clear LCD display. The interface makes it easy to select the welding process, to switch on the synergic programs and to set all advanced parameters precisely, including the pulse and double pulse characteristics. The panel allows your own settings to be saved and recalled, which speeds up work on repeating tasks a great deal.
