=== ✅ 2. F1621P THC Parameters (Voltage + Motion) ===

For 1.6 mm sheet, you want very smooth, low-aggression motion.
Thin plate bends FAST with heat, so THC must respond — but gently.

===== Arc Voltage (most important) =====

At 32 amps on 1.6 mm, your correct arc voltage will be:

👉 Set Voltage = 104–112 volts
(check with a test line; every machine varies slightly)

Here’s the general setting pack:

==== 🎯 Critical THC Parameters (F1621P) ====

| Para                   | Setting          | Notes                                              |
| ---------------------- | ---------------- | -------------------------------------------------- |
| P05 – AVC Stop Voltage | Set Voltage + 5V | e.g. if set voltage is 110 → P05 = 115             |
| P06 – Threshold        | 3 V              | THC reacts only if voltage differs more than 3V.   |
| P07 – Sensitivity      | 10–15            | Thin sheet needs smooth motion, reduce aggression. |
| P03 – Auto Up Speed    | 20               | Slower = smooth height correction.                 |
| P04 – Auto Down Speed  | 20               | Prevents nose-dives into the plate.                |

==== 🧰 Other Support Parameters ====

| Para | Setting | Why                                    |
| ---- | ------- | -------------------------------------- |
| P14  | 6       | Smooth braking                         |
| P15  | 10      | Smooth reversing                       |
| P08  | 1.0 s   | Emergency retract                      |
| P09  | 3–5 V   | Small voltage bump after collision     |
| P10  | 1       | Enable IHSV (optional but recommended) |
