Hot Arc Ignition Regulation:5-100A. Output Curent Re gulation:10-200A. This machine ITS200 is a newly upgraded two-in-one multi-function welding machine with TIG/MMA welding function, which can DIY welding copper, steel, iron and other metals. The design concept is: “reduce tedious operation steps and improve work efficiency”. The clear operation panel and intuitive data display are convenient for users to operate and greatly improve the user experience. IGBT technology has timed out the lightness of the body, making it more convenient to carry. Inverter technology enables the persistence of machine work. TIG Welding: Argon gas is required, and how many welding methods are available, such as spot welding, continuous welding, etc. Depends on different welding machine effects and welding machine habits. There is no requirement for the size of the tungsten needle, 1.6, 2.4, 3.2 and other diameters can be used. MMA Welding: Does not require any gas, requires welding rod. The easiest way to solder is to use a non-technical and DIY soldering, depending on the welding effect. Note:There are no tungsten electrodes. And argon gauges in the package.
