The 4 wires coming off the idler module go to the ignition switch, idler solenoid, CT1, and ground.

If the above approximate voltage is present at IM terminals C and E then idler module IM is suspect if it won't release (de-energize) the idler solenoid.Īlso, I found a 1999 Champion 16 manual that has a schematic with a 1996 date stamp. A 150watt light load at one of the receptacles should register approximately 1VAC between IM terminals C and E. If the unit won't come off low idle under electrical or weld load then either the Current Transformer CT1 is defective or the Idler Module IM is.ĬT1 can be checked by measuring for a low AC voltage between wire #8 (terminal C) and wire #10 (terminal E) of the idler module with a load on one of the auxiliary power outlets or weld load.

How to check Champion 16 idler module and current transformer: follows: Brick, 10,253,734 fire brick, 493,400 drain- tile, 516,013 terra cotta ware, 18,000 pottery and stoneware, 2,463,681 and porcelain ware. Ran across this while searching on my hard drive for some of my Hobart repair files. If I can find it, I'll post it as he may have the tech manual to this spec #. Somewhere I've got a phone # of one of the original Hobart engineers. They supported the pre-buy out machines for awhile but that went away after a few years. When ITW bought out Hobart, all engine drives and electrics 251 amps and higher were sold to the parent company of Thermal Dynamics (can't remember its name) and that's when Thermal Arc was born.

All Miller-made Hobarts use the Miller s/n nomenclature, 2 letters 6 digits. The reason you cannot pull up anything on the Hobart website is because it's part of Miller/ITW. If you ever called their tech support back in the day, you'd give both #'s to help them find the correct schematics for the machine you were calling about. Also, like Lincoln's code #, Hobart used to use the spec # on their welders also. Back before the ITW buy out, that's how Hobart used to do their s/n's.

Guys, that is the correct serial # for that machine. Hobart must have had several welder with similar enough faces they didn't have a manual for each one.Ĭan someone lead me to a schematic of the idle control module, or a replacement. I can not find a schematic of the control panel, or even a manual for this specific welder.

I'm pretty sure one wire come from the auto on/off switch on the front panel.

The idle control circuit looks pretty simple with only 9 components on the board. I checked the solenoid by putting 12 volts directly from the battery to the two wires while the engine was running. The solenoid activates when it gets 12 volts. Removed carb and intake and adjusted the valves, clean the carb, new air filter, oil and filter. I got it de-dobbered, cleaned pretty good. Been setting in a PU bed trailer with a topper on it for 13 years! Serial #: 93WS24614, spec. I got a Hobart Champion 16 that was going to be salvaged.
