Key benefits and features of the BJC welding machine
The BJC welding machine is designed with the user in mind - it offers top-notch features that make work easier for beginners and ensure perfect accuracy for experienced welders:

Advanced digital inverter technology: Provides stable welding current, high efficiency and low power consumption.
Clear LCD display: Allows easy monitoring of parameters, setting of welding current and selection of operating modes in real time.
VRD safety system (Voltage Reduction Device): The no-load voltage reduction system ensures that the power is turned off within milliseconds after welding is finished, drastically reducing the risk of electric shock.
HOT START (0 - 40A): Function for easier arc ignition by temporarily increasing the starting current. Fully adjustable (setting to 0A disables the function).
ARC FORCE (0 - 40A): Automatic adjustment of the electric arc dynamics for a more stable and uniform weld without electrode sticking.
LIFT TIG welding: Allows TIG touch welding (requires additional accessory/torch with gas valve, not included).
Active cooling and overheating protection: A built-in high-efficiency fan (with a dedicated operation icon on the screen) and an overheating indicator ensure a long service life of the device.
Extremely quiet operation: Despite its exceptional power, the noise during operation does not exceed 75 dB.
Smart electrode thickness indicator: A convenient visual guide on the screen that suggests the optimal electrode thickness for beginners based on the set welding current.

Frequently Asked Questions (FAQ)
1. What materials can I weld with this welding machine?
The machine is extremely versatile and is suitable for welding a wide range of materials, including ordinary steel, stainless steel (inox), copper and aluminum, depending on the selected welding method and the appropriate electrodes or filler materials.
2. What is the VRD system and why is it important?
The VRD (Voltage Reduction Device) is a key safety feature that reduces the voltage on the electrode to a completely safe level within milliseconds after welding is completed. This drastically reduces the risk of electric shock, which is especially important when working in damp areas or on metal structures.
3. Is a TIG torch included in the package?
No, the TIG torch/handle with gas valve, which is required for LIFT TIG welding, is not included in the basic package. It is available as an accessory that can be purchased separately.
