I have a holding tank that is made out of carbon steel and it has developed two pin sized holes which are now leaking water. This tank is not a pressure vessel it is a tank with a heated water jacket. Anyway I haven’t done any welding in years and that was with a stick welder…. would I have to drain the tank as I would hate to waste all that water?
Would one of those cheap migs from haborfreight using flux core do the job or would I be better off using one of their cheap ac/dc arc welders?
