Sounds like a thermostat is overreacting. If you can call the manufacturer that will help. Good luck.

there is probley nothing wrong its called duty cycle.which means that if you are welding long periods or welding at max amps the welder will kickout to cool down.Look on your unit for the tag that tells imformation about your unit.It will show something like 30% duty cycle so that means you can weld 3 minutes at full power before the unit shuts down.

1/4" plate with a 135 amp machine is probably beyond it's duty cycle abilites. If you are using a mixed gas, and pushing the max on the settings, it will be cutting out because it is designed to.
You might want to get a higher amperage welder for consistent welding of 1/4"
The 140 Pro maxes out at 5/16" using inner shield wire. and 1/8", or 10 guage with gas.

O.C is Over Current, this basically means that the welder has been "Overloaded" and it has had to try to supply, too much? current, and it has failed, the "Computer" has "Detected" this and has indicated this error code.
Most often when this occurs some or all of the output semiconductors "Blow" and are damaged or destroyed, however "other" things may also be involved.
The very best thing you can do to achieve the lowest down time and the cheapest outcome will be to engage a professional.
Contact the manufacturer and ask for a referral to an authorised repair service center, when it contact here simply first ask for a "Quote" as to prospective costings and go from there.
If one still insist on DIY, then one simply MUST first obtain a service manual, and work through the troubleshooting steps within, also this manual has all the parts numbers needed to obtain replacement parts. Most often board replacement is the only option, if indeed parts can be obtained from 3rd parties.
Internal fuse inline with the transformer output to the gun.

Check the internal fuse. If that is okay, check all connections and check for continuity across the heavy windings. Transformer may have burned open at a power tap. Or the heavy contactor burned out.
If you do not have a manual, They do not have any douwnloadable at their website http://www.fsh-welding.com If you do need to contact them, I hope your French is up to snuff-

I hope you solved this problem. It can be fixed, but the best option is to get a new welder. A lot of people get just the welder, and they forget about the equipment that should go with it. This is how welding injuries happen. That will not happen to me, I have everything from the welding gloves to the welding table. Having stuff like that makes the job much easier, and it is also safer. If you want to know more about welding tables check out https://afterpaints.com/best-welding-tab.... I was able to make a much better decision about which welding table to get after reading that article.
