First ever HH210 problem

[MAC702]

Serial number is LG210009Y.

It welds just fine, but now when I go to tap #2, there is no output or wire feed. All other voltage taps work just fine.

If no ideas, I'll give Hobart a call this week, but maybe it's something simple?

[Zrexxer]

Obviously you were trying to use it in an application where Tap #2 was not the correct voltage, and the HH210 is so smart that it disabled itself on that setting to protect your weld quality.

Actually, I got nothin'. I have no doubt though that the Hobart Experts will do what they do, and get you fixed up.

I'm guessing you're back stateside now?

Mac,

Have you pulled the cover yet and looked for a disconnected wire ?

Have you checked the sector switch out with a meter?

[Hobart Expert Keith]

Mac,

Like Dan said, check the switch for a disconnected wire. If all appears good there, it most likely is the switch. Give us a call and we can get you fixed up.

Ya,,, but,,, who would he find qualified to replace a switch???

[Hobart Expert Keith]

I think we could trust Mac to handle that if need be.

Another likely suspect, also targeted at the selector switch, would be a loose connection at the wire that goes to the #2 position. Also, on the opposite side of the switch, there's a bussed common connection. Check for loose screws on that bus as well.

Check wire terminals for evidence of heating first, then try blowing out the switch with compressed air but try not to blow crap into it and you could try spraying some contact cleaner into the switch while rotating it to different positions. Then blow out any excess contact cleaner and try it again. Failing that replace switch

When you get it fixed, please let us know what is was. It is allways good to be able to search and find fixes.

Okay, sheet metal is finally off and all connections are tight on that switch. I double-checked the one that the schematic shows as belonging to position #2. I can feel no difference when switching through #2 compared with switching through any of the other positions. There is still a big click when the trigger is pressed but there is no wire feed and no weld voltage.

If you have a volt meter handy, measure the AC voltage on the back of the switch when the switch is in the 2 position.

Measure between terminal #11 (common) and terminal #4. If you have about 230V then the swith is bad.

[MAC702]

Nah. Hobart Expert Keith messaged me that the switch is bad and has already mailed the new one. Now, if the new switch doesn't fix it, I might be tempted to poke things at it...

[MAC702]

New switch is here. Nobody better be timing me on how long it takes me to get off my *** and swap 'em...

Got 'er done yet, Mac????!!!

[SundownIII]

Done yet Mac??

You taking the day off???
