IDEAL EXPERT MIG 550W PULSE Pro7 LCD Professional Water-Cooled Inverter Welding Machine

EXPERT MIG 550W PULSE Pro7 LCD is an inverter-based, synergistic and multifunctional welding power source designed for MIG and MAG welding, flux-cored welding, TIG Lift welding and manual metal arc welding with covered electrodes. The unit supports single-pulse and double-pulse welding modes, ensuring precise heat input control, arc stability and excellent weld appearance, especially when welding aluminium and stainless steel.

The device is suitable for maintenance work, structural steel fabrication, heavy industrial production and automotive body repairs.

The machine is used for brazing galvanized sheets and welding stainless steel, carbon steel, low-alloy steel and aluminium. Welding is performed using inert, active or mixed shielding gas depending on the selected gas and wire on the control panel.

The seven-inch touchscreen display enables fast and intuitive synergic adjustment of welding parameters. The user sets material type and thickness, and the intelligent arc control system automatically selects optimal parameters step by step. Manual arc length adjustment and weld appearance customization are also available.

Available modes include spot welding, two-step mode without trigger lock, four-step mode with trigger lock for long welds, extended two-step mode and extended four-step mode.

Adjustable parameters include pre-gas, post-gas, wire feed, burn back, voltage correction, spot welding time, inductance control and current rise and fall settings.

Pulse and double-pulse modes allow adjustment of arc length in pulse, arc length at initial and final current, base current in pulse and pulse duration.

TIG Lift mode allows adjustment of welding current, current fall time, final shielding gas flow, trigger mode and material thickness.

Manual metal arc welding includes hot start, hot start time and arc force functions.

The JOB memory function allows storing and recalling welding programs.

Physical Parameters

The device is equipped with a water cooling unit with flow indication, increasing efficiency and protecting the torch from overheating.

The cooler and fans operate in normal and smart modes, activated only when necessary, reducing internal contamination.

The machine includes overload, overvoltage and undervoltage protection for generator operation within plus or minus fifteen percent voltage fluctuation.
