Hey guys finally got round to digging out the old snap on/cobra welder Iv had laying in the garage for to long. Sadly to say the wire feed isn't working to good all. Just slipping. Tried all different tensions, replaced liner with a steel liner, new swan neck liner, no change. Been look at the conversions people's been doing on the small diy welders. Iv been using a small clarke 90 (borrowed off a friend) that has poor wire speed also. Any suggestions would be much appreciated. I'm no welder by a loooooooong shot, but these machines can't be doing me no favours either haha. Running 0.8 wire along with argon/co2.
