AT the risk or being repe***ive- CONTACTOR......If you spot/s***ch weld a lot it won't last but a few years.....ESPECIALLY if any length of extension cord has been regularly used. Also .....if these welder companies have "ears" here- please make the next version welders, out of even cheaper foriegn components -so it will break at the store- to save us from hauling them back to your store.....
