I have a 180 SD that is probably around 5 years old, but has gotten VERY little use until recently. I mainly weld stainless steel exhaust and some aluminum parts. One day the high freq decided to stop working, so I continued to use the machine by scratch starting. Then it decided to latch high freq on at all times, causing me to send it in for repair. $700 later with a new main board, the machine will now weld ok, but the arc is really instable. It tends to jump around quite a bit. I've tried different tungstens, consumables, and work pieces. The high freq gaps are within factory specs. What else can I try? My repairman says everything internally checks out ok, but I am not happy with this new instability. Please help! If the main board needs to be replaced again, I need to know soon because there is only a 90 day warranty on it. Thanks! Adam

I (and others) would be interested in hearing how this story turns out.
If you would, please let us know what ends up being wrong and how much it costs to fix it.
Thanks

The $700 estimate sounds like the main board that others have mentioned.
The $700 is also conveniently about half the price of a new SD180.
Coincidence? I think not.
As it has been explained to me, Miller would rather see you and I buy new product than fix existing machines. Set the repair costs high enough and most people will buy new with a warranty.
Any idea what you are planning on doing?
Ebay is where a lot of "working" welders end up.
