WS7 Series IGBT Inverter HF TIG Welder (WS7-400)
Basic Info
Model No.: WS7-400
Product Description
Model NO.: WS7-400 Current: Inverter Current Application: All Size: 590*306*500 Trademark: MORROW Origin: China Type: ARC Welders Model: Ws7 Color: blue Power: 3-Phase 380V/415V Specification: ISO9001 HS Code: 8515319000 Features
1. Adopt the soft switch technology, high efficiency, low power consumption
2. Automatic protection from overcurrent, overheat, over/under voltage
3. Support TIG welding and MMA welding
4. Up/down-slope of welding current continuously adjustable, pre-gas sending and delay gas sending
5. HF automatically strikes arc, and automatically extinguishes after the arc is successfully stroke
6. 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.
7. 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
8. 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
9. Can be equipped with the distance control box to realize distance control, simplify the operation
10. 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
11. A voltage fluctuation of ± 20% is allowable
