Thanks for the info!! I have a Hobart27i - and wiring looks similar but I’m very nervous about the instructions from Langmuir. They say follow the clamp lead for the negative and the positive hooks to the torch lead.
In your photo - is the work piece clamp wire to the post on the right?
It looks like you hooked the THC red wire to this post and the black THC wire to the middle.
Is this correct?
Thanks -
