For years I have had an old hand-me-down set of oxy/acetylene torches.They leak sometimes and are basically junk. I don't use them very often but since I started restoring my 51 chevy pu I find I need torches more often.I need to buy a new set. I noticed a Hobart medium duty set that is reasonably priced. Are these ok for occasional use?I will use them for heating/bending metal,fastener removal,and brazing.thanks---Jack
