F1621 Plasma THC:
F1621 VS F1620:
The installation size and interface of F1620 and F1621 are exactly the same. The latest F1621 is added with dynamic perforation function.

Description:
F1621 THC is a product with simple operation, stable performance, complete functions and cost-effective performance based on the use of plasma power on-site and absorbing the advantages of many domestic and foreign torch height controllers.

It uses the basic constant current characteristics of plasma power supply, detects the change of plasma cutting torch height by detecting the change of plasma arc voltage, and controls the height between cutting torch and work-piece in real time. It is suitable for the height control of plasma power cutting torch with constant current characteristics or constant current characteristics within a certain voltage range. It is especially suitable for the height control of cutting torch of portable, desktop and gantry cutting machines.

The device is light and portable, simple to operate, easy to use. Its buttons and knobs are humanized design, which is comfortable and convenient.

Features:
- Adopting high-brightness digital tube and LED lamp as arc voltage and signal indication, clear display, stable anti-interference and long service life.
- Use keys and digital knobs to adjust and operate parameters, easy to use.
- Its panel adopts a 60-degree inclined plane installation method, which is suitable for portable CNC cutting machine operation.
- Built-in voltage divider and shielded by metal at all angles, the overall volume is smaller and the anti-interference ability is better.
- Built-in simple parameter setting, you can flexibly change the operating parameters to adapt to various complex working conditions.
- It can adapt to external working conditions by changing the parameters, without any adjustment to the internal hardware of the device.
- The effective level of input signal can be set. The input signal is valid when the default is low level. It can be changed to be valid when there is high level.
- The input and output are all isolated by optocoupler, which effectively protects it from over-voltage and interference electromagnetic pulse damage.
- Arc starting relay and the arc starting success relay use power relays for Omron, which work reliably.
- During various work processes, the real-time level of input signal can be viewed.
- Different work processes are locked to each other to ensure no misoperation.
- When the height controller has a perforation delay, the dynamic perforation function can be used during arc starting.
- In the cutting process, real-time monitoring of whether the arc is actually started, if the arc is broken in the middle, the height controller will promptly notify CNC system and turn off the arc relay to avoid long-time arc starting in the air when the arc is broken.
- In the process of automatic height adjustment, ensure that the actual arc voltage always closely follows the set arc voltage, and there is basically no static difference.
- During automatic height adjustment process, arc voltage setting value can still be changed, so that cutting torch height can be fine-tuned in real time during the cutting process.
- In the process of automatic height adjustment, collision signal can be fed back to the CNC system to avoid the collision and the CNC system still moves forward.
- In the process of automatic height adjustment, the arc voltage intelligent adjustment function can be used.
- After the cutting is completed, the height controller automatically lifts the cutting torch, and the lift height can be set arbitrarily.

Torch Holder Lifter:
Description:
The torch holder of flame cutting machine is of top quality in the industry. The lifting body uses a decelerating DC motor to drive the cutting torch up and down. The internal lifting drive of the holder adopts 304 stainless steel T-shaped screw, and the optical axis and linear slider are used at both ends to ensure smooth and reliable verticality in the up and down direction. It is used for ascending and descending transmission mechanism during flame cutting. Made of aluminum with fine treatment, it features very high accuracy. The positioning switch and limit switch are made in Taiwan and have passed 3C certification and CE certification.
