Im considering buying an old Hobart Linear 1 welder. Will this type of unit run off a home duty ac/dc welder? Will a standard gun and cable work on this unit? How long ago were these welders manufactured. Are any sources left for parts?
Thanks in advance for all assistance
Brian
HI BRIAN........WELL YOUR IN TROUBLE IF YOUR GOING TO BUY IT.......THE LINEAR 1 WAS REPLACED BY THE LINEAR II.....BOTH WERE OBSOLETE MANY YEARS ABOUT 1986-89 TIME FRAME. I AM SURE NO PC BOARDS FOR THE LINEAR I ARE AVAILABLE.....THE UNITS ALSO HAD A PUSH PULL GUN SYSTEM ON THEM..... IN OTHERWARDS BOTH REQUIRED A SPECIAL MIG GUN AND I DON'T THINK THEY ARE AVAILABLE ANY LONGER EITHER......... I THINK I WOULD PAS ON THIS ONE HOWEVER THE CALL IS YOURS IT IS YOUR MONEY................WHAT MACHIEN WERE YOU THINKING OF PUTTING THIS ON, MY BROTHERS AND I HAD OUR LINEAR1 ON A CYBERTIG MACHINE, AC/DC..........IT WORKED GREAT AS LONG AS YOU REMEMBERED TO TURN THE HIGH FREQUENCY OFF. IF YOU FORGOT IT ATE THE PC BOARD IN 2 TENTHS OF A SECOND AND TURNED IT INTO A SMOKEING PIECE OF JUNK PC BOARD..... BUT IT IS YOUR CALL HAVE FUN WITH IT.............ROCK....... SSCOTT@MILLERWELDS.COM
Brian, The Linear I was Made for welding Aluminum, It was a Push pull feeder which Made it easier to feed the Aluminum wire without bird nesting. This was built for a Mig power Supply and will not work properly on a Stick welder. #1 The gun will always be hot because there is no contactor in a Stick welder.#2 The Open Circuit Voltage will be around 80 volts which will cause the wire to burn back to the tip easy.
As Rock said I would also pass on this and go to something you can use.
Thanks
