View Full Version : old hobart g-200 question
12-01-2007, 10:59 PM
Hello guys, new guy here. Thanks. My Hobart g-200 welds fine for ranch work, except it doesn't idle down when I quit welding. Have to manually throttle it back down. Any ideas why? Also, when I plugged the electric drill into the 110 outlet it fried the drill's switch...is the outlet output adjustable? Welder is powered by an old Willys.

The outlet on this unit is DC so any AC device plugged in will fry almost immediatly ( ask me how I know ). The idle device is a mechanical unit and is subject to vacuum leaks or blockages. See if needle valve at bottom of unit is plugged or the vacuum line to it. Look under the coil assembly there is a metal slug with a rubber washer under it. That washer often leaks or the slug gets stuck in the coil. Also check the diaphram that pulls back the throttle is not leaking.
Good luck !

The outlet on this unit is DC so any AC device plugged in will fry almost immediatly ( ask me how I know ).That's not true. Any brush-type universal motor such electric drills, grinders, and other portable power tools will work fine on DC. That's why they're called "universal" motors.

It is true that universal motors will run on DC however, variable speed controllers on drills and some grinders will not. They fry as soon as they are turned on. So moral is, don't plug your variable speed drill into a DC outlet.
