Product Information

Powerful welding capacity

Provides a 300A output welding current. Performs well with electrodes from 2.6mm to 6mm. The duty cycle reaches 100% at 40°C, allowing the HK300A and MMA300PRO to continuously weld at 300A without overheating.

Equipped with a digital meter

Accurately displays the real-time welding current, enabling control the welding current when turning the Ampe button.

LED indicator light

The light indicates when the internal temperature of the machine exceeds the allowed level or when the machine is in an overcurrent condition. This ensures the durability and longevity of the machine.

Arc Force function

When there is a short circuit (electrode sticking to the workpiece), the Arc Force function provides a welding current higher than 20-50% of the initial set current. This helps stabilize the arc, reduce electrode sticking, and prevent arc interruption during low welding currents.

Hot Start ignition

Automatically adjusts the current to be higher than 20-50% of the initial set current when igniting. Facilitates easy ignition, even in challenging conditions such as damp electrodes, or unclean welding surfaces, or when using difficult-to-ignite welding rods.

Energy-saving with an automatic cooling fan mechanism

The cooling fan works when the internal temperature of the machine reaches approximately 52°C. After cooling, the fan will stop when the temperature drops to around 40°C. This helps save energy and minimizes intaking dust into the machine.

Accessories included:

Extended electrode holders DK DKJ70-95 (Quantity: 2).
