Is the wire spool also driven by a motor also.

admin

Just changed out my first 10 lb spool of wire and I noticed that the wire spool was not being driven. I was under the impression that it was also driven to help keep the stress off of the wire drive. The welder is a Lincoln Pro Mig 180.So does the wire spool just sit there and have the wire pulled off the spool by the wire drive roll.

Reply:there should actually be tension on the spool.It should be loose enough so that the drive wheels can pull it and feed the wire, but tight enough so that when you let off the trigger the tension on the spool stops the spool from turning as well.hope that made sense.
Reply:Yea that makes sense and I don't know why I thought it was driven.Thanks for clearing that up.
Reply:Push/pull systems actually have a brake on the spool to keep it from unwinding. You will only make the mistake of leaving the spool too loose once, Ask me how I know, lmao.The difference between art and craft is the quality of the workmanship. I am an artist.
