Slow throttle reponse to load

I am trying to operate a suitable welder using this generator. However, the throttle response is too slow when I strike an arc and begin welding. This causes my arc to drop off just when the generator is about to reach full-throttle. So once the arc load is gone, the engine throttle slows down again, and the cycle repeats. If I have someone hold the throttle open manually, the problem doesn't exist, until the welding process is interrupted. Then the throttle issue repeats..

    Thank you, but the welding manufacturer said the generator size is suitable.

    I understand that the wattage may be right but unless that genset has a shut off for current sensing, you are always going to have this issue with lag.

Put something else on the generator (like a light bulb) so that it senses a load, otherwise you wont be able to deal with the load sensing and the lag.

Your welder is too much for the generator you are using. Usually you need a fairly big generator for welding so it doesn't overload so easily.

How do I fix my generator


the first thing that I can think of is your engine speed is to slow causing the frequency to be below 60 hz. At half the hertz 30hz the tool will run at half the speed and most likely burn out since most tools are not built to run at variable frequencies. A 4 pole generator (the norm) needs to run at 3600 RPMs under load. Unloaded they are set at 3750 RPMs since they'll slow down slightly under load. There are many throttle setups for small engines so I can't give you a step by step on adjusting the throttle arm on your machine without seeing it. Oh, just a thought, does it have auto-idle button. If so turn it off, for some reason it is not sensing the load. If you have a multimeter with frequency on it, you can use it to help set the rpms.

Why wouldn't my em5000sx honda generator not run my rheem gas heater.


  • The Auto Throttle System switch needs to be in the off position.
  • If the generator has not been used for awhile than the fuel is stale and the generator may be slow in responding to the load change. Replace fuel with fresh fuel.
  • Attach a second load such as a 100 watt light bulb standard bulb with a tungsten filament. Observe the light as the heater cycles. If the light goes very dim than the generator is slow responding to a load change. Generator carburetor needs to be cleaned, tune-up. Run fresh fuel under load to see if carburetor will clean itself.
  • Try adding choke to see if richer mixture reduces voltage dip. Check manual for mixture adjustments.

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)

Generac ix 2000 how do I adjust fuel mixture


im not suure what you mean about "Bog" but this gen is only good to 1600 watts cont. (2000 peak) and it has a auto throttle so it will idle down all by itself when not loaded past say 40% of total load , but if you think your having fuel starve problems try all the simple things 1st Fuel filer (inside tank) clean carb and stuff like that , I do fix allot of small engines with a good strong dose of stp fuel treatment and i never need to take em apart

Ranger8+ diesel will not weld or generate.


Check for proper placement of all springs & linkage on carb / throttle. One of those springs and/or linkage pieces is largely responsible for idling UP the engine so that it will be able to operate the welder & generator. If it won't idle up, it won't work right.
