I have a Hobart 110 volt mig that I bought many years back. Never used enough to get good at it. Dug it out and been using it on some sheet metal repair on a '65 Mustang. Still not realy getting the hang of it. In talking to a few friends who have more experience than I do and figured out that mine has a non adjustable gas regulator and theres all have an adjustable regulator. Will and adjustable regulator be worth the cost?

I may be mistaken and I do not know what your welder looks like but most of the time the gauge set is attached to the tank and you set your flow rate into the machine . Are you using gas or are using flux core wire. What is the model number on the machine maybe you should check with Hobart
