Lorch T220 DC TIG fault

[abelee]

Hello everyone, I have a Lorch T220 DC TIG welder with a ControlPro control panel. The program is locked in hot wire welding mode. I believe its hardware is exactly the same as a regular TIG welder, so could you please help me restore its welding function?

Hotwire welding mode? You mean the terminals are always live?

Hotwire welding mode? You mean the terminals are always live?

Hot-wire mode follows the same underlying principle as TIG mode—it’s a complete, integrated welding process. The issue I’m encountering is that the welder has been forcibly locked into hot-wire mode and cannot be switched to MMA or TIG mode.

Where did you get the binary?

Got a 220 DC and maybe can make a dump.

These one I got.

你从哪里弄到的二进制文件？

我有一台 220 DC，也许可以导出数据。

它来自CPU板上的24LC256 EEPROM。我认为它仅用于存储配置参数，而不是固件。

如果您能帮我读取您机器上的 EEPROM 内容，我或许可以进一步确认该功能配置是否存储在 24LC256 中。

我买到了这些。

这套设备真是令人羡慕——可惜的是，我的机器只有热线焊接功能，不像你的机器那样有TIG或MMA焊接功能。

The reply:

It comes from the 24LC256 EEPROM on the CPU board. I think it's only used to store configuration parameters, not firmware.
If you could help me read the contents of the EEPROM on your machine, I might be able to further confirm whether the function configuration is stored in the 24LC256.

This setup is really enviable—unfortunately, my machine only has hot wire soldering capabilities, unlike yours which has TIG or MMA soldering capabilities.
