An arc force DC IGBT inverter welding machine (MMA) with VRD
is a type of welding equipment that is used for manual metal arc welding (MMA) processes, also known as stick welding. It utilizes an inverter technology, which uses high frequency switching to control the welding current and voltage, resulting in a more efficient and stable welding process.
The arc force feature of the welding machine refers to the ability to adjust the welding current during the welding process to maintain a stable and strong arc, even in adverse welding conditions, such as when welding on rusty or dirty surfaces.
The DC (direct current) output of the welding machine is suitable for welding a variety of metals, including steel, stainless steel, and cast iron. It also has a VRD (voltage reduction device) feature, which is a safety feature that reduces the open circuit voltage of the welding machine to a safe level when the machine is not in use, to prevent electric shock.
The IGBT (insulated-gate bipolar transistor) technology used in the welding machine allows for a more compact and lightweight design, as well as improved energy efficiency compared to traditional transformer-based welding machines. This makes it easier to transport and use in various welding applications.
Overall, an arc force DC IGBT inverter welding machine (MMA) with VRD is a versatile and reliable welding machine that is suitable for a variety of welding applications, while also providing enhanced safety features and energy efficiency.
