My brother-in-law has a small 110v Snap-on welder. NIGHT MARE from day one.

In a nutshell consumables are tough to get...apparently there were 3 mfgs of this model and all are not created equal to to find contact tips even is a pain.

I do countersales at a company and we also sell welding supplies. People come in with HF and other discount welders or in this case off brand welders and cna not find repair parts or as I said even consumable with out just "making do".

Stay with a name brand and in the long run life will be much happier.
