MHP50 cannot set 30 sec WeldTime in CONFIG.TXT

Brutus

Hi there,

Firmware is 2.01 (MHP50APPV201.hex & MHP50UIV200.hex)

Problem:
MHP50 unit -
Menu > Reflow > WeldTime = 60-300 sec

MHP50 CONFIG.TXT
WeldTime  = 80 #(Sec:30~180)

30 sec WeldTime cannot be made and maximum end time is either 180 sec or 300 sec. Please repair the firmware.

Kind regards,
Bruce

Thanks for finding the bug. The comment in the configuration file is wrong. It should be #(Sec:60~180). I changed the code.

Thank you for the quick update, did you also correct the MHP50 Menu > Reflow > WeldTime = 300 sec?

You say #(Sec:60~180) is correct.... can I suggest shorter WeldTime #(Sec:30~180) for small PCB.

Last Firmware was 2025.1.9: APP V2.01 do you have any plan to announce new Firmware?

Kind regards,
Bruce

This time is set with reference to the temperature of the constant temperature range of reflow soldering, ensuring that there is enough time to make the temperature of the entire PCB and components uniform, to fully activate the flux in the solder paste and to volatilize the solvent components in the solder paste
