Features
■ Adopt the soft switch technology, high efficiency, low power consumption
■ Automatic protection from overcurrent, overheat, over/under voltage
■ Support TIG welding and MMA welding
■ Up/down-slope of welding current continuously adjustable, pre-gas sending and delay gas sending
■ HF automatically strikes arc, and automatically extinguishes after the arc is successfully stroke
■ In TIG welding, the long/short seam switch can support the switch between continuous welding and discontinuous welding. The build-in circuit guarantees a good arc-ignition and crater filling, and endows the machine with such features as easy to start arc, arc heat concentrated, good gas protection result, etc.
■ In MMA welding, can be used together with all kinds of electrode with a diameter below 0.5mm. In TIG welding, can weld stainless steel, alloy steel, copper, silver, titanium
■ With arc-striking current adjustment switch, can easily adjust the arc-striking current, optimize the arc ignition effect. The pushing current adjustment knob can strengthen the arc force and prevent the welding electrode stuck to workpieces
■ Can be equipped with the distance control box to realize distance control, simplify the operation
■ Can be used in welding the stainless steel parts, pressure container and pipeline, realize TIG grounding and TIG covering once a time, greatly improve the working efficiency
■ Wide range of supply voltage, as wide as ±20%
