RSN7-800 Drawn Arc Stud Welding Machine

Small size, less weight, energy saving and environmental protection, exportable, suitable for power by generator (saving 30%-40%), workable from 3-AC 280V to 440V.

Applicable projects: kiln, boiler, shipbuilding, power plant, chemical engineering, mechanical equipment, various pipeline, vessel, bucket, vehicle manufacturing etc. thickness ≥ 2mm, welding M4mm—M20mm pins, studs, pin bolts, special-shaped pins, corrugated pins, anchoring parts etc. similar studs and bolts.
Applicable materials: carbon steel, low alloy 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.

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.
