Subject to technical modifications   2.  shear stud Welding machine Advantages Double gun Stud Welding machines are equivalent to two separate machines work simultaneously without disturbing the welding operations, high welding speed, good welding quality and high welding efficient. Why not use two separate machines instead of one double gun machine? RSN7 double gun stud welding machines possess the features of single gun IGBT Inverter stud welding machines as well as the following advantages: (1) Two set of movements, one machine enclosure and auxiliary body, low price, less weight and high efficient. (2) Due to the integration of two set of movements, good conformity and quality, strict requirements for each small parts. (3) When only one of the two guns is in operation, two movements can produce maximum current and weld larger-diameter Weld Studs, which is impossible for one single-gun machine. (4) In case one of the movements fail to work, the other movement can still work continually without influencing the operating process. The rate of failure is very little thanks to dual-core technology. (5) Dual-core Welding Machine, like the dual-core technology of computer, two movements can separately work well, double the welding speed and the price of the machine is reduced by 30%.   3. Special Applications (1) high speed railway Apply to the situations of busy and large scale welding tasks. Due to busy workload, 3-4 welding machines cannot meet the time limit of a project. If adding more welding machines, the power capacity will be deficient, and there will be no enough electric cables for machines. Double gun machines can avoid the welding dilemma.)   (2) high-rise buildings It will take averagely 4 days to construct one floor. Considering the clear working day (due to no welding in raining) and the time of installing and laying floor decks and binding the steel bars, the time left for welding is very limited. Temporarily adding more machines will face the trouble of deficient power capacity and inadequate preparation. Dual-core welding machines can solve these problems.   4. Applicable welding projects   steel construction, floor decks, bridge, embedded parts, heavy machinery, industrial factory buildings, high-rise buildings, power plant buildings, chemical engineering buildings, shipbuilding, metal construction, electromechanical equipments, etc. thickness ≥ 3mm, weldable studs: Φ10mm, 13mm, 16mm,19mm, 22mm, 24mm (shear connectors, stud welding studs, round corner studs), M4mm—M36mm studs, pins and similar studs and bolts. 5. Applicable welding materials carbon steel, low alloy steel, stainless steel, copper etc. materials with arc weldability. Welding in the workpiece surface of oxide layer, oil slick, priming paint or electroplate. After welding, no deformation, no convex, downward position welding, vertical position welding, overhead position welding, all position welding. 6. Features (1) Soft switch inverter transformation technology, small size, less weight, energy saving and environmental protection (electric saving 30%-40% comparing with Thyristor rectifier welding machine), efficient EMI design, low pollution to power grid. (2) Internal structure modular design, perfect control and protection functions, use pure IGBT device, safe and reliable whole machine, low fault rate, no demanding for professionals, general electrician can repair and maintenance. (3) Circuit board is under waterproof, anticorrosion, dampproof and dustproof treatment, which is applicable for high humidity and poor environment projects, such as field operation, tunnels and high-rise buildings etc. (4) Stepless regulation of welding electric current and welding time, digital display of welding parameter and input voltage. Detection and display functions of input voltage are one of the distinctive features of “YIFA” welding machines, through which the welder can conveniently understand the power voltage without the assistance of instruments. (5) Dormant welding machine fans can save energy, reduce dust and dirt of inner equipments, and increase lifespan by 3 times higher. (6) Compensatory capabilities of power voltage. When the voltage decreases, this machine can automatically stabilize welding parameters, when the voltage is extremely low, the machine still can work normally(only the max welding current is a little lower), the welding strength is much higher than ordinary welding machine. This feature applies to: electricity shortage and require multiple devices at the same time construction works such as engineering powered by generators, shipbuilding, steel structure etc. (7) Welding time can be controlled manually and automatically. Suitable for many welding process. (8) The welding parameters have been set in the panel. It is very easy to operate. (9) Reasonable output voltage design, extended use of welding torch cable. Sustainability of high load, high resistance to fatigue. (10) Can be scheduled to manual metal arc welding, carbon arc gouging (11) The special torch structure and large lifting force in circuit welding torch, low heat, durable, the whole welding process is finished automatically. Ordinary welder can learn the operation in 20 minutes, and can weld skillfully in 1 hour. (12) High strength electrostatic coating steel plate, chassis, high corrosion resistance     Packaging & Shipping    1. Packaging (1) Outer package: sturdy plywood cases accessible to pallet. (2) Inner package: welding machines covered by bubble covers and inside fixed by battens with nails; matched welding guns and other accessories packed by corrugated cartons. (3) Container loading: 38 sets for 20GP, and 80 sets for 40GP. (4) The package can be designed according to clients' requirements.   2.

Company culture Innovation As the products of high technology, Stud welding machine will gradually substitute traditional welding machine, which will break the existing industrial benefit balance and shape our role as showstopper and revolutionist, so we will structure the following three advantages to meet the challenges: 1. Miraculous marketing innovation 2. Industry-leading technology innovation 3. New economic pattern innovation by integrating information, management and resource Responsibility Everyone is responsible for the company success, anyone who is not provided information will not undertake the responsibility, but anyone who has grasped the information cannot escape from the responsibility. Responsibility produces self-consciousness. Distinguishing all the responsibilities and then practice them, it’s difficult, not necessary and inconformity to our company benefits. YIFA seldom ascertain where the responsibility lies, but we dislike the staff who will shirk responsibility, escape from responsibility, fear to take responsibility and claim not the responsibility of himself. The staff who fear to take responsibility are not competent for any leadership, and regarded as disagreeing the company culture.
