Can customize according to product requirements.
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)
1, speed is very very fast, efficiency is very high.
2, adjustment is very easy
3, controller can store 15 welding schedules, to suit different specification workpieces.
4, efficient weld, can weld multiple weld points with only one time.
5, 2 foot switches control 2 different welding schedules, to control 2 PCS spec. Workpiece.
6, Universal application
7, Upper arm of machine is insulated, no short circuit.
8, Machine body of thick steel sheet, not easy to deformation, good rigidity.
9, Microcomputer control, accuracy and steady
10, Water cooling transformer: Use silicon sheets of 15000 gauss permeability to pile up.
11, Fast solenoid valve, making welding speed faster.
12, Cylinder adopt high accurate, anti-friction hard material, which is duralumin, without rust, lower friction, lower noise and loading is faster.
13, Our machining equipment is more advance, fine workmanship.
14, Higher efficiency.
15, Lower loose weld rate, less welding dregs.
16, It is easy to operate machine. Performance of machine is more steady, can be used 24 hours, lifetime 15 years.
