So, I imagine you came to us through a search for Hobart, which is great, except we only work with Hobart’s foodservice line. Hobart Welders is owned by ITW, just the same as Hobart foodservice, but there’s not really an overlap in parts.
I did find another forum on the web just for Hobart Welders, so hopefully you will have some luck there!
Additionally, I tried to run a manuals search on their site, but came up empty. The site says if the search comes up empty, you should contact firstname.lastname@example.org to see if they have a manual for you.
