Error code Lorch t220 ac/dc (E 09)

[Jweld]

Good morning, I've seen bug fixes on Lorch.
I have a lorch t220 AC / DC and I sometimes get the error code E 09 (photo attached).
I would like to know if it has ever happened to you and what the solution could be.
I have dealt with several Lorch distributors in Spain and have not received a response.
Thanks a lot

I have the T220 pro.

E09 is listed as current/voltage detection......Contact service.

I presume it would be the same for your welder

I cant upload the file here.....

If you pm me your email address I'll sent it on....

E09.

If the Error is permanently displayed, it means that the machine is measuring a very fast rise in the primary current internally. So it shuts down and displays E09 as a safety warning to prevent further damage. This could be due to a failed/defective IBGT or secondary Diode. It could also be less sinister and perhaps a loose connection from the primary transformer. So check the wires.

If it is intermittent, it is very unlikely to be anything serious. Causes could be...

HF Tracking inside the machine (Check torch insulation)
There is a flat ribbon cable that goes from the X10 port on the Mapro PCB to the Port X1 on the PFC PCB. Make sure its not become loose or anything like that.

If you need anymore info, please PM me the serial number and email address and I will send you a service manual and/or put you in touch with a local service centre who could assist.
