MMA inverter welding machine Infinity 120ACD, 10-80A, 230V, Telwin

• Direct current (DC), MMA electrode inverter welding machine, 80A.
• Supplied with accessories for electrode welding.
• Usable electrodes: rutile, basic, stainless steel, cast iron, etc. up to 2,5 mm.
• Advanced arc control tools: Arc Force, Hot Start, Anti-Stick.
  • The Arc Force function This helps maintain a stable arc even in difficult conditions, such as dense welds. With the Arc Force function, the inverter automatically adjusts the current depending on the length of the arc. If the arc accidentally touches the workpiece, the current increases, so it does not stick. If the two are too far apart, the current will be reduced and the arc will not extinguish.
  • Thanks to the Hot Start function, it helps to ignite the arc more easily by automatically increasing the current at the beginning of the welding process. This can be especially useful for difficult-to-ignite electrodes. Facilitates arc ignition for materials that are too cold or too thick.
  • The Anti-Stick function prevents the electrode from sticking to the workpiece, reducing the current connected to the electrode when it detects sticking. This makes it easier to remove the electrode and reduces the risk of overheating.
• Thermostatic Protection: A heat-sensing system that shuts down the machine if the temperature rises too high, preventing overheating.
• Overvoltage protection: Protects the machine from higher than normal voltage levels, which can damage the electronics or the internal parts of the machine.
• Undervoltage protection: It comes into operation when the supply voltage is too low, thereby helping to maintain the stable operation of the equipment.
• Overcurrent protection: Limits current through the machine to prevent overloading or damage to electrical components.
• Compatible with the engine generator (230V, +/-15%). High stability of the welding current even when the supply voltage fluctuates, so the machine can maintain a consistent welding current even when the supply voltage fluctuates, thereby ensuring continuous, reliable welding performance.
• Lightweight, compact design, easily portable welding machine hung on the shoulder
• Moderate consumption thanks to inverter technology. Inverter technology consumes moderate current in welding machines because it makes the conversion of electrical energy more efficient. Inverter welding machines convert high-frequency AC (alternating current) electrical signals into DC (direct current) signals and then back into AC signals at the desired voltage and current level. This process allows finer control of voltage and current, reducing energy consumption and unnecessary heat generation. In addition, the inverter technology increases the performance and efficiency of the welding machine.

MMA (Manual Metal Arc) welding is an arc welding process, also known as manual metal arc welding or stick welding. This method uses a consumable electrode (welding rod) that melts simultaneously with the arc and serves as a filler material in the weld seam. MMA welding is often used in outdoor applications because it is less sensitive to wind and dirt than other welding methods. It is suitable for a wide range of metals, including steel and iron-based alloys, and is well suited for thicker materials and structural work.
