Magnum MIG 501-S WDP15 Dual Puls MIG/MAG welder
The Magnum MIG 501-S Dual Puls is a powerful industrial power source designed for the heaviest tasks in production plants and factories. This modular unit, with 500A of welding current, was created for the highest output and dependability. Thanks to advanced functions such as full synergy, double pulse and an integrated liquid cooling unit, it is an uncompromising answer for high quality welding of thick steel structures, stainless steel and aluminium in the most demanding industrial conditions.
Key features
Huge welding power of 500A at a high 60% duty cycle
Advanced Dual Puls technology for welds with the finish of TIG
Full synergic control that simplifies the settings for different materials
Modular build with a separate 4 roll wire feeder
Efficient liquid cooling unit for long welding at high power
Professional four roll feeder (4x4) that keeps the wire feeding steady
The right answer for heavy industry, production lines and welding thick material
Technical details
Technology in detail
The heart of the machine is advanced double pulse technology (Dual Puls), which modulates not only the welding current but also the wire feed speed. That gives full control over the weld pool and over the look of the bead, creating the typical fish scale effect, ideal for visible joints on stainless steel and aluminium. Full synergic programs automate the choice of parameters and ask the operator only to set the material type, the gas and the wire diameter. All of it rests on a solid modular build with a separate four roll wire feeder and a cooling unit, which guarantees dependability when working with long torches and during production cycles that run for many hours.
Recommended applications
- Heavy industry and production lines
- Welding thick steel and aluminium structures
- Production plants and factories
- Shipbuilding and rail industry
- High output and automated welding processes
Control panel
The control panel was designed for professional industrial use. It has a legible digital display plus clear knobs and buttons that let you pick the welding method precisely, switch the pulse functions on and move through the extensive synergic programs. It gives full control over every key process parameter, including current, voltage, pulse balance and arc dynamics, so the welding characteristic can be matched to the specific demands of the job.
