Question edited for clarity. If it was running before with no problems, I switch or controller is unlikely to have suddenly failed. The most likely answer is the the mouse wiring repair has caused the fault, bad connection missed connection, misplaced connection.

ONLY: If your Bobcat T650 is displaying the M1732 code, it indicates a problem with the fuel pressure sensor circuit. This could be caused by a faulty sensor, damaged wiring, or a problem with the engine control module (ECM). To start troubleshooting this issue, you should first inspect the wiring and connections for any signs of damage or corrosion. If everything appears to be in good condition, you can test the fuel pressure sensor using a multimeter to check for proper resistance values. If the sensor is found to be faulty, it will need to be replaced. If the sensor and wiring are both in good condition, the issue may lie with the ECM. In this case, it is recommended that you take your Bobcat T650 to a qualified technician who can diagnose and repair the problem.

My welder will only run above full at full line it dies why

Replace fuel pump.

Ask here, they will find every Bobcat manual or schematics.

I had a problem like this a few days ago try taken of the air filter to were u can see the choke it may not be opening rite just cause it opens don't mean itsnot opening rite get a small spray bottle put gas in it and as u start ur welder spray the choke with with the gas a lil if it starts turn ur switch to run for while it workd for me if that don't maybe change the spark plugs

turn up your amps

Just had a quick look at the specs of your Bobcat welding/generator. It is quite a tool and offers both AC and DC MMA as well as other types of welding and a high capacity AC generator.. This suggests the Bobcat is far from an ordinary engine driven welding set that is typically DC only. It is probably an AC generator coupled to inverter technology that gives it the capability of offering those different welding options. That means there is some quite fancy electronic circuitry inside. I would guess if the generator is working well the lack of welding performance is likely to be caused by an electronic problem and is a job for a specialist. Checking the OCV or open circuit voltage between the welding ground and electrode should provide a clue - according to the specs it should be 40 volts on both AC and DC.

I would make sure the brushes are free in the holder and the collector rings are clean. You can hold fine emery cloth to the rings while it is running. If this does not work. you mar have to excite the generator. Robert

You can check this website maybe it helps you Bobcat CARKNOWLEDGE

check for all safety micro switches are operational--sit in seat , have bar pulled down , foot on the brake or hand brake on

First off, check all of your welding cables to make sure they're in good shape, then check for tight cable connections. Is your machine staying at low idle speed while trying to weld? If so, Switch the idle select into the 'weld' position and make sure the high RPM's initiate. Try welding again. Better? Could be a number of things, if not.

An open fuse means there is no continuity going thru fuse. It was over loaded and blew the fuse. Basically it melted the internal lead inside fuse. It is designed when when more amps flow thru fuse it heats up and melts the material inside fuse so it protects the curcuit and prevents damage to curcuit.

You will need to see if fuel runs out of fuel line attached to carb. If it does that indicates the filter is not plugged. The next thing is to remove fuel bowl and check carb. float and check that it is not stuck in theup position. This float should be hinged and move up and down freely. When it is in the down or hanging position you should see fuel coming from needle and seat. When you lift float it should stop. If this is happening then you have debri in the ports in the carb. and it is going to require to be diassembled and cleaned out all the ports to make sure the proper amount of fuel and air is going through the carb. The fact that you can squirt gas in carb. and it runs means the ignition system is working. Make sure the fuel tank is clean and always drain fuel bowl at the end of season if you store for long periods of time. Also use fresh fuel if it has set for long periods of time.
Good luck.

What doesnt speed up to weld? the feeder? is the wire burning back? are you getting any wire? this is gmaw / wire right? sounds like it may be running slow
