Powermat MMA Welding Machine PM-MMAT-300L, 300A, 230V

The PM-MMAT-300L welding machine is an inverter welding machine made using IGBT transistor technology. It has a clearly readable LCD screen that displays the current welding current value. The welding machine is cooled by a fan and has protection against overheating.

The welding machine operates in the 20-300A range and allows welding with electrodes from 1.6 mm up to 5 mm in diameter. The device is very light, making it exceptionally portable. Additionally, it has a convenient carrying handle. The standard EURO connector is intended for welding cables, allowing you to easily choose additional welding cables. Using large fans in the small device body increases airflow, which reduces the temperature of the transistors. The efficiency of the device reaches up to 60%.

The device has the following features that facilitate the welder's work:

• Hot Start - temporarily increases the welding current above the value set by the welder. This function makes it easier to ignite the arc.
• Anti Stick - interrupts/reduces welding voltage and current in case of a short circuit between the electrode and the material to be welded. This function prevents the electrode from sticking.
• Arc Force - stabilizes the arc regardless of its length. Lowering this function's value provides a softer arc and less penetration, while increasing it allows for deeper penetration and welding with a short arc. At the highest Arc Force value, it is possible to "push" the electrode into the molten metal pool and burn through the material. This model has automatic Arc Force adjustment.
• VRD - a voltage reduction system designed to turn off the power within milliseconds after welding. This function also reduces the safe electrode voltage. The VRD function switches the welding power on and off when there is sufficient electrical resistance between the electrode and the workpiece, measured during operation. Upon stopping the machine, VRD automatically reduces the secondary voltage between the welding clamps from 105 V to 14-24 V (this takes a few milliseconds).
