DNW2 Series CNC Automatic Spot Welders Machine for Mesh
Method named for welders: Row welder series: DNW1/DNW2-P-L
DNW1: Pneumatic AC row welder with only upper cylinder
DNW2: Pneumatic AC row welder with Upper cylinder and lower cylinder
P: Rated capacity
L: Throat depth (Length of arm) Feature and advantages: There are Manual type and CNC Automatic type, also can customize according to product requirements.
-controller can store 15 welding schedules, to suit different specification workpieces.
-efficient weld, can weld multiple weld points with only one time.
-2 foot switches control 2 different welding schedules, to control 2 PCS spec. Workpiece.
- Universal application
- upper arm of machine is insulated, no short circuit.
- Machine body of thick steel sheet, not easy to deformation, good rigidity.
- Water cooling transformer: Use silicon sheets of 15000 gauss permeability to pile up. There is cooling water in inside, using full copper alloy core not aluminum, reducing impedance, improving the utilization of power, 20% duty cycle to ensure the requirement of long time welding, big output power. The useful lifetime is longer, noise is smaller, structure is more compact and reasonable.
-Fast solenoid valve, making welding speed faster, speed is very very fast, efficiency is very high, therefore decreasing cost.
- Cylinder adopt high accurate, anti-friction hard material, which is duralumin, without rust, lower friction, lower noise and loading is faster, thereby reducing the weld spatter.
-Our machining equipment is more advance, fine workmanship, so welding machine's precision is higher.
- Lower loose weld rate, less welding dregs.
- It is easy to operate machine. Performance of machine is more steady, can be used 24 hours, lifetime 15 years.
-Suitable for wire mesh, cover of wire mesh, storage rack, cage for garner, gridiron, wire shelving, storage shelving, trolleys etc. Model Unit Item | DTN-25 | DTN-40 | DTN-80-1 | DTN-100-1 | DTN-150-1 | DTN-200-1 | DTN-80-2 | DTN-100-2 | DTN-150-2 | DTN-200-2 |
