Once powered, the screen will light up. Here is how to program your weld time.
Some boards drift in timing accuracy. To recalibrate:
Before diving into the manual specifics, it is crucial to understand what this board is. The XH-M608 is a digital timing control module specifically designed for capacitive discharge (CD) spot welders. Unlike continuous current welders, this board controls the discharge time of high-current capacitors (or a large battery bank) to fuse nickel strips to lithium-ion battery terminals.
Common Applications:
The board is often paired with high-current MOSFETs (like the IRF3205 or similar) and a separate power supply. Without a proper manual, most users fail to calibrate the timing correctly, resulting in burnt nickel strips or weak welds.
If you’ve recently purchased an XH-M608 battery spot welding control board, or if you’re struggling to get consistent welds from your DIY 18650 battery pack assembly, you have likely found yourself searching for one specific document: the XH-M608 Manual.
While the device is a popular, cost-effective solution for hobbyists and small-scale EV battery builders, the manufacturer often provides a sparse, poorly translated pamphlet. This article serves as the comprehensive, unofficial manual for the XH-M608. We will cover everything from pinout configurations and wiring diagrams to advanced parameter settings and common error codes. Xh-m608 Manual
While you have the full text here, many users prefer a printable PDF. Unfortunately, the generic Chinese manufacturer does not host a dedicated website. However, you can find the original XH-M608 manual PDF in these locations:
(Note: Specifications may vary slightly depending on the specific manufacturing batch. Always check the silk screen printing on your specific board for voltage ratings.)
At its heart, the XH-M608 is a dual-channel relay module with optocoupler isolation. Impressed? Don't be. That just means it's an electric switch that can be flipped by a tiny signal (like from an Arduino or a sensor) to control big, scary things (like a 220V lamp, a water pump, or your neighbor’s annoying garden light).

Think of it as a weakling whispering orders to a bodyguard. The microcontroller whispers “On” – the relay’s electromagnetic coil clunks – and suddenly, high-voltage power flows.
Common programmable parameters (may vary slightly by firmware version):
| Code | Meaning | Typical Range | |------|------------------------|------------------------| | P0 | Set temperature (SP) | -50 to +120°C | | P1 | Hysteresis (differential) | 0.1–15°C | | P2 | Control mode (heating/cooling) | H (heat) / C (cool) | | P3 | Calibration offset | -10 to +10°C | | P4 | Delay start (compressor protection) | 0–10 min | | P5 | High temperature alarm limit | up to 120°C | | P6 | Low temperature alarm limit | down to -50°C | The board is often paired with high-current MOSFETs
