idealarc 250 polarity switch

admin

Idealarc 250 code 7279. The switch has two fiber parts that the contacts ride on those parts are broken. The local welding store say's I can't buy parts have to buy entire switch.I hate to spend almost $300. if I could just buy those parts. Any help would be appreciated.
Reply:Might be able to find a used switch somewhere probably about half price. Check with Stumpfs - 618-566-4733    www.stumpfweldingsupplies.com
Reply:If you can't buy the parts, why not try to make them? The fiber is just to isolate the the current, correct? Why not use a cutting board (plastic) like you buy at wally world and cut it to fit? Just a thought, maybe I'm way off base.Only when the last tree has died and the last river has been poisoned and the last fish has been caught will we realize we cannot eat money.                                         -Cree Indian ProverbSA 200 LincolnVictor Torches
Reply:If you are like most, probably only use it DC+  , just hard-wire it, tape the extra wires off.The fiber is most likely Micarta, looks like a laminated fiberglass, available in different thicknesses.  Can be cut and drilled easily to fit.  It's been years since I've bought any (pre-internet), I'm thinking electric-motor rebuild shops, especially ones that do large DC motors.  Assuming I got the spelling right above, could always do a google search ...
Reply:I will try Stumpfs. I'm told that if it doesn't have perfect contact that the switch can get hot from arcing and may melt plastic. Sounds like it is micarta I will see if I can get some. THANKS GUYS
Reply:the code 7279 is an AC only welder and does not have a polarity switch.at code 7100 they changed the switch. the $300 switch is a kit for the older machine that includes new conductor straps ( like wires) after code 7100 the switch is only $189Go look at your code number again. Are you looking for the line power switch or AC/DC polarity switch.
Reply:My machine is labeled code7279 it is ac dc, all I know is what it says on the machine. I was told by Nordan Smith a new switch is $300 but later was told a kit was about $180. The Lincoln website had a drawing of the switch for code 7279 doesn't look like mine but is ac dc I think mine was updated. If I can figure out how to put a picture on here I will, thaks for your input . Micarta done the trick thanks JSFAB
