What is Chopper in Welding?
A high-performance plasma arc power source design using semiconductor switching techniques. Also called Pulse Width Modulation (PWM).
What is Chopper used for in Welding?
Chopper technology is used in welding to help create a more consistent and stable arc. This results in better weld quality, increased productivity, and reduced costs.
How does it work?
A chopper is an electronic device that breaks the DC power supply into discrete pulses. These pulses are then applied to the plasma torch at a very high frequency (usually in the range of 100-500 Hz).
The result is a much more stable arc with less oscillation, spatter, and overall variability. This makes for a smoother, higher-quality weld bead with fewer defects. In addition, choppers can be used to increase productivity by allowing for faster travel speeds and shorter weld times.
What are the benefits of using a chopper in welding?
There are many benefits to using a chopper in welding, including:
- Improved weld quality.
- Increased productivity.
- Reduced costs.
- Greater arc stability.
- Smoother weld bead.
- Reduced spatter and oscillation.
- Faster travel speeds.
- Shorter weld times.
Chopper technology is an essential part of modern welding and plasma cutting. A chopper is the way to go if you’re looking for better weld quality, increased productivity and reduced costs.
