Very helpful and interesting.
I have run into the problem of the HF failing to establish an arc, so I too have scotched through the oxide with the tungsten; I’m pleased to learn it’s not a fault or quality issue with my inverter.
Good to hear the warning it’s a waste of time to check and fine tune the settings on a hot test plate.
Here’s another reason to test settings on switching a machine on: my inverter failed on switching on one day - i had full amps all the time - but until I worked out I had no control, I blew half a dizen holes.
Very helpful to realise AC frequency is a “level 2” setting priority, whereas AC Balance and gas flow rate are “level one”, as well as by how much to increment adjustments.
Many thanks Brad & Jody.

Fascinating, Sam. Would a silicon bronze facing have been an option? I was merely wondering that silicon bronze and the mild steel pin might wear better than mild steel on mild steel. I appreciate that the original design was mild steel against high carbon steel.
Was the job caused by a failure to carry out good maintenance ie regular lubrication?
Very interesting to see how you determined the nature of the casting.
Looking forwards to the follow-on.
Thanks, Sam.
