Lincoln IDEALARC SP-250 Gun

Featured Replies

My dad’s welder doesn’t get hot. A welder repair shop told him it is the gun. I’ve searched online for replacements, but none of them have the same pin arrangement. They all have the same pins as what is in the last photo. Even the online owner’s manual has pins like those in the bottom photo. 
 

Has anyone any experience with guns for this welder?

How old is the welder?  Have you contacted Lincoln Electric home office? It MIGHT get you the parts or at least information but since they've changed owners you may now have a ghost welder. 

If you can't get parts you may have to replace the whip and receptacle on the machine.

That was a board I had found. If I understand what I read correctly, he can switch to one of the standard guns, but will lose the ability to make adjustments for some things on the fly that he used to do with the guns microswitches. I’m taking the pictures by the local welding supply place sometime this week to ask them if they can tell me anything about it. 

I would go with the simple gun and not worry about being able to make adjustments at the gun. A lot less to go wrong and at a better price.
