The MMA 160 Speedy welding rectifier is used for manual direct current welding of structural steel with coated electrodes (MMA method).

It is an inverter device, manufactured from the most technologically advanced components made in the IGBT technology .

The welder is equipped with automatic HOT START functions to facilitate ignition and ANTI STICK to facilitate detachment of the electrode in the event of sticking and protecting against damage to the device.

The welder is used in closed or roofed rooms, not exposed to direct weather conditions. It is intended for casual and amateur work.

WORK CYCLE

The duty cycle is based on a 10-minute period. 60% duty cycle means that after 6 minutes of operation, a 4-minute break is required. Duty cycle of 100% means that the device can work continuously without interruption.

LEVEL OF SECURITY

The IP defines the degree to which the device is resistant to solid and water contamination entering the device. IP21 means that the device is suitable for operation in closed rooms and is not suitable for use in rain and snow.

HOT START FUNCTION

The HOT START function is popularly known as hot start. It works when the arc is struck, causing the welding current to temporarily increase above the value set by the welder. HOT START is designed to prevent the electrode from sticking to the material and is a great help when striking the arc.

ANTI STICK FUNCTION

The ANTI STICK function is a short-circuit protection that reduces the welding current if the electrode sticks to the workpiece. This makes it easier to detach and protects the device against damage.
