Mike -

I sent an email to Ray - should I copy you too?

Straight argon (known good bottle on - welds OK on a blue machine) at about 12-14CFM - and no, the thin tungstens are pretty much grenading.

Funny you mentioned flushing the 4053, had a counter chip on a Ten-Tec radio that would go wonky and only running it from off to full-scale a few times would reset it.

The Max setting amperage reading varies from 227 - 230 Amps in 2T/DC mode. What's interesting is that I'm not seeing the amps at the Min setting drop below 90 indicated - I seem to remember this going down to the mid 20's?

Could someone contact me tomorrow so we can start getting this all resolved? I don't mind patching in another IC - although I'll most likely just socket the bug - but knowing which IC to replace where, and which diodes to check would be useful.

Would really like to get the machine back up before the 25th - we're having another class at my shop & I'm a bit bored with listening to "Worthless, unsupported Chi-Com RPOC, ya shudda bought a QUACK, Quack, quack...."

Cheers
