Can customize according to product requirements.
Method named for welders
Row welder series: DNW1/DNW2-P-L
DNW1: Pneumatic AC row welder (only upper cylinder)
DNW2: Pneumatic AC row welder (upper + lower cylinder)
P: Rated capacity
L: Throat depth (Length of arm)
Feature and advantages:
-Fast welding speed, high efficiency
-Easy adjustment
-Microcomputer control, high accuracy and stability; controller stores 15 welding schedules for different workpieces
-2 foot switches control 2 welding schedules (for 2 workpiece specs); one-time welding of multiple points
- Universal application; insulated upper arm (no short circuit)
- Thick steel sheet body (good rigidity, not easy to deform)
- Water cooling transformer: (15000 gauss silicon sheets, full copper core, low impedance, 20% duty cycle, long service life, low noise, compact structure)
-Fast solenoid valve(higher productivity, cost reduction)
- High-precision duralumin cylinder (rust-proof, low friction/noise, fast loading, less spatter)
-Advanced machining equipment, fine craftsmanship, high machine precision
- Higher efficiency.
- Low loose weld rate, less welding dregs; easy operation
-Stable performance, 24-hour operation available, 15-year service life
