Technical Characteristics

Technical characteristics:
• Advanced control technology. High efficiency and Energy saving.
• High duty cycle. The contactless point control technology is used in the main circuit, the reliability of the machine is high.
• Stud welding or Manual Metel Arc welding can be selected. The welding current and welding time can be set. The welding parameters are stable, which provides a reliable guarantee of the stable welding quality.
• The welding current and the welding time can be displayed, and have an over-heat protection LED indication.
• Short welding time, which can be set between 0 and 3 seconds. Heat Affect Zone of welding is small, so the post-welding deformation of the work-piece is very small.
• Suitable for welding of carbon steel, stainless steel, copper, aluminum and its alloy studs, the machine can be widely used. The diameter range of studs is Ф6~Ф25 (RSN-2500) /Ф30mm(RSN-3200).
• Fast welding speed, high quality of welding joint.
• Small volume, light weight, easy to move and beautiful appearance.
• Three phase 380V, 50 Hz power supply.

About Us
Zhejiang Kende Mechanical & Electrical Co., Ltd.
Zhejiang Kende Mechanical & Electrical Co., Ltd.

Kende strictly controls quality in every link from raw material purchase to product delivery, carries out strict quality supervision and controls the quality of purchased raw materials. In production links, Kende carries out the first-piece quality inspection system and guarantees consistent product quality. Kende attaches importance to production details. Before product delivery, Kende conducts a random check on products. Kende carries out the one-vote-down system and effectively prevents substandard products from entering the market.

At present, Kende has many products. All kinds of welding machines, including Manual Metal Arc (MMA)or Stick welding machines, Tungsten Inert or argon Gas (TIG)shielded arc welding machines, MIG (Metal Inert Gas)/MAG (Metal Active Gas)or Gas shielded Metal Arc Welding (GMAW) machines, Submerged Arc Welding (SAW)machines, Resistance Spot welding machines, Laser welding machines, Laser cleaning machines, Robot welding system and Air Plasma Arc Cutting machines. All types of battery chargers, including 6V, 12V and 24V chargers.All types of heaters, including electric heaters, LPG fuel gas heaters and diesel and kerosene or fuel oil heaters.

Tungsten Inert Gas(TIG)arc welding machines include WSME AC/DC series TIG welding machines, WSM series TIG welding machines and WS series TIG welding machines. AC/DC and pulse current TIG welding processes can weld thin, medium-thick and thick materials, for example, carbon steel, stainless steel, copper brass, etc. Excellent arc characteristics, good welding performance and high quality.

The representative products of manual metal arc (MMA) welding machines are the IN series welding machines, double-supply voltage series MMA welding machines, all supply voltage MMA series welding machines and the wide-voltage, waterproof and dust-proof high-performance welding machines, greatly improve the adaptability and service life of welding machines and can realize good welding performance and high quality.
