Description:
This MMA welding machine, built with IGBT inverter technology and a full-bridge design, is ideal for welding with coated electrodes under various working conditions. Features such as arc force adjustment, hot start, anti-stick function, and wide voltage input (160–420V) make it a highly efficient and flexible choice for professional and general welding tasks. The dual-layer design also enhances the machine’s durability and stability.
⚙️ Key Features:
-
MMA (Manual Metal Arc) Welding:
Suitable for welding various metals like steel, cast iron, and stainless steel using coated electrodes. -
Full-Bridge Topology:
Enhances current stability and welding quality while improving energy efficiency. -
IGBT Chip:
Offers lightweight design, energy savings, and high-quality stable arc performance. -
Adjustable ARC Force Knob:
Allows fine-tuning of the arc force for better arc control, especially in difficult positions or with special electrodes. -
Built-in Hot Start & Anti-Stick:
-
Hot Start: Temporarily boosts current for easier arc ignition.
-
Anti-Stick: Reduces current automatically when the electrode sticks to the workpiece, preventing damage.
-
-
Wide Voltage Operation (160–420V):
Operates smoothly in areas with unstable or varying power sources. -
LIFT TIG Compatibility:
Can also be used for Lift TIG welding (argon-based precision welding).
