Hi there,
This sounds like your idle control module has gone bad. Since the machine will rev up to weld speed if you turn the switch to high it can't be that the solenoid has gone bad. Some models of engine driven welders from Miller use a little module, others have the idle circuit built into the control board, can't tell which yours is without a model number. This problem could also indicate a broken current transformer since letting the unit heat up makes things better. I'd use an ohm meter to check the resistance of the CT while it was cold to see if it goes from open circuit to just a few Kohms of resistance when it gets "room temp".

Rank me if this helps,

Start OK but if after warm up I push the choke to run, the engine stops, I used 4 time before and idled OK


Push choke to run???then not use on a all ready warm engine you mean you push the GAS lever ? remember a choke can work as a throttle for the engine. it can have a double function if your electric start contact is damaged you can use it to stop the running engine also.
How long you are owner of the machine , read the manual about it !
If before it worked good on this kind of proceedings as described ? then if you mean you push the gaslever to run Try it to do it again without the airfilter. I THINK YOU HAVE An AIR problem by carburator if its so clean the airfilter if its not to old. or replace
You can use for short time the choke in most cases minimize use of the choke short not more then 2 times max you pull.or electric start.
AND very important control in any case allways for THE RIGHT OIL level !!

If the engine is warm(hot) do not use the choke forget it it has no use. control your spark plug electrode i think you will find the cause.

What is wrong with the idle on my welder? the switch works , it idles up when I switch it on high and it idles down when I switch it down but it wont go up when I strike an arc or use power tools, what...


There is something wrong with the auto load sensing switch which is part of the generator. That is the sensor that detects when current load from the generator drops as in when you strike an arc or turn on a power tool and cranks the throttle to full power. It is obviously working on manual because the manual switch is cranking the revs up so the solenoid that operates the throttle is ok. My advice is to take it to a service centre that deals in welder/generator sets as you are playing with dangerous voltages and may possibly damage the machine by tinkering with it or fry yourself (nasty)

Hi:

Your plasma has a start arc pilot inside the machine, this one must be faulty, check your owner's manual and request the part to your nearest welding store. It is easy to replace.

My bobcat 225g runs full bore all the time, I thought it would idle then when you strike an arc it would pick up speed,


A welder does not speed up when an arc is struck. It is normal for a gas welder to stay at a high rpm. If it did not, it would be very hard on the machine as a high amperage is needed to start an arc for welding, and to be consistant. Unlike a generator which will "idle down" when not in use.

WHEN I TRY STRIKE AN ARC WITH A ROD YOU HAVE TO HIT IT 5 OR 6 TIMES TO GET IT TO WELD ITS HARD TO KEEP IT GOING BUT AFTER 4 OR 5 SECONDS IT WILL BURN LIKE NORMAL (USING PROPER AMPERAGE)


Is this on new rods as well as one's you'be been already welding with? Depending on rod types, some will "flux over" the end, after welding insulating the tip. When you're welding at a low setting, with a small rod, sometimes it is hard to start an arc. A 7018 rod is a good example of this. Strike the rod like a woodden match, or drag it on the metal, to expose the rod. It also depends on your welder. Some have settings to help start an arc and then control the current. Older transformer welders arn't that smart and are less forgiving on low current thin metal settings.

301 wont high idle when striking arc


There is a small electronic control board inside the welder that senses current flow and pulls up throttle. It could be the board has a problem, or the throttle solenoid itself. You'll have to do a bit of checking.Check for loose connections or blackened components on the control board.

Engine missing


Get a DMM that can measure frequency (Hz), then check that with no load and the idle control set to off the frequency is 61.5 Hz - If it isn't you have to troubleshoot why it isn't and correct it.
You should also check the idle control mechanism if there is one on the generator, with it on the generator should start up at regular speed, then slow to idle speed, then rev back up to regular speed when you draw current from the generator. To check it use the DMM to measure the speed at startup ( should be 61.5 Hz), when it idles down (about 37 Hz), when you're drawing power from any other outlet ( pretty close to 60 Hz). If the generator has idled down and you shut off the idle control it should rev back up immediately.
