You can always start w/something smaller for now until you really master the task of tig welding.Keep the machine waxed & super clean.And when you are ready upgrade,some in the same pos. you are in now will be willing to step up buy your machine to save a little dough and maybe the sale's tax.Call the local welding supply store has any demo's you might score a few bucks off retail.the Lincoln sq,wave 225 is a great machineat a resable price.I have a sq.wave 275 awesome,Also have a miller 200DX I use it for roll cages and super thin sheet metal.
