200dx. Can hear relays clicking on and off when machine not being used..

[PeterA]

My 200dx sounds like it is clicking relays on and off all the time when it is not being used. I have it on AC settings and it randomly has clicking noises coming from inside.


ideas?

I've not heard anything of this. You should call tech support and discuss it with them. ext 207

I know I'm being a bit of a smart ###, Sparky the ghost must be close by.

Unplug it and see what happens. As the main power switch is a circuit breaker that cuts all power, unless one leg isn't being cut, I can't see how the machine could get any power. Is the gas shut off?

I think he means the relay clicks on and off while power on. I had to re-read it and that was what I got. But like Mark said, best to call support. Does it weld OK?

Yes machine is still turned on with led display on.

I actually have holes appearing when welding, did an example weld only using just the tungsten and no filler. Whether or not this a gas related issue or contimanation as opposed to a electrical issue I not know. I did this weld on a bit of 1/2" thick flatbar to show the issue. I never weld 1/2", was just using the thicker aluminium to see if it too would give the bubbles.
It does this on 3mm 1/8" thick aluminium too. Is that just what happens to aluminium if you heat it up and do not use filler. I would love to see someone else do a similar test.

Also, tungsten so. I have always used 2% lanthanated. Boss went to the store to get supplies, I said we needed more tungsten so, gave him the old pack and off he went. Came back and the store did not know what they were and do not sell lanthanated. So he ended up with the white tip Ceriated.
What I did notice was the weld beads were considerably shinier and cleaner with ceriated.

PeterA,

You've posted this "bubbles" photo on Welding Web already and have received feedback too.

Are you now shopping for a new answers or do you just like to show the picture?

Again, shove some rod into the puddle and move the torch.

Quit blowing bubbles and being mystified by it. Ha, ha, ha...

You should seriously consider joining that sheet metal by some other means such as using rivets or spot welding.

Is it possible to spot weld aluminum?

That doesn't sound much like a Relay to me, I'd be thinking that's High Voltage arcing out. It's more of that kind of Snap....

Look around it in the Dark while it's doing that, you might catch sight of a flash

[PeterA]

well, that sounds interesting because there seems to be a 'flat spot' on the pedal when using the machine too. Where is just has no power and is a very bard arc. I did start another thread for that.

How long have you owned this machine ?

[PeterA]

Couple years I guess.
