It can change work frequency to medium frequency so as to replace the traditional hulking work frequency transformer with the cabinet medium frequency transformer. Thus, it is characterized with portable, small size, low consumption and etc.\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003e \u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eMachine has excellent performances: constant current output makes welding arc more stable; fast dynamic response speed reduces the impact from the arc length fluctuation to the current; accurate step less current adjustment and pre-setting function. There are also some automatic protection functions for under voltage, over current, over heat, etc. inside the welders, when the problems listed before occurred, the alarm on the front panel is light and at the same time the output current will be cut off. It can self-protect and prolong the using life and greatly improved the reliability and practicability of the welders.\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003e \u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eMachine can also realize TIG operation. While MMA operation, if the electrode touches work piece over two seconds, the welding current will drop to the minimum current automatically to protect the electrode. While TIG operation, the minimum current will be outputted firstly until the arc is ignited by lifting method, the output current will rise to the present value, which can protect the electrode. At the same time, the arc force and hot start will be provided with MMA operation.\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003e \u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eMain function feature\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003e \u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eMachine is with automatic protection function for overheating, overcurrent and low voltage.\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eArc force*(thrust current) function is possible in machine.\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eMachine can be working with generator as power supply.\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eMachine is with feature of output current automatic compensation function which is much helpful for the 50m welding cable work.\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003e \u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eConfiguration\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eMachine is with digital display meter for possible working parameter.\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eMachine is with high efficiency IGBT for more than 30% energy save.\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eMachine is with unique patent for machine case design with feature of waterproof and dustproof.\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003e \u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eApplication\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eWelding rod:\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003e80A machine, 1.6-2.0mm\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003e120A machine, 2.0-2.5mm\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003e140A\/160A machine, 2.0-4.0mm\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003e180A\/200A machine, 2.0-6.0mm\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003e \u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eMMA output voltage feature:\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eSingle phase family type machine and normal type machine is with 24.5V-25.7V output voltage.\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eSingle phase industrial type machine is with 31V output voltage to meet high weld effect.\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003e \u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eFunction: DC MMA and Lift TIG (simple argon arc welding process)\u003cbr\u003earc force adjustable, hot start adjustable\u003cbr\u003eLCD screen\u003cbr\u003e\u003cu\u003eWith remote control device for welding current adjustment\u003c\/u\u003e\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003e \u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eWelding material:\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eCarbon steel, high alloy steel, stainless steel, cast iron and so on.\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan\u003eModel\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003ePower supply: 1-220V +\/- 15%\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eNo load voltage: 65V\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eDuty cycle: 40%\/40℃\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eMax. working current: 180A\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eProtection: IP21S\u003c\/span\u003e\u003c\/p\u003e","brand":"Keysdaq","offers":[{"title":"Default Title","offer_id":47675657584795,"sku":null,"price":450.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/2751\/0683\/files\/remote.jpg?v=1765020160","url":"https:\/\/keysdaq-shop.com\/products\/mma-portable-lb2025180lcdr","provider":"Keysdaq","version":"1.0","type":"link"}
