Ive read a lot of the posts out there with the same issues. I ordered two new PTC fuses (incase I mess one up.. its 0.50$)
My welder will feed no issue with no wire tension. If you click the trigger about 20 times, the PTC will heat up and stop the motor. Ive checked the other circuits in the board and they are all good. I cleaned out the motor and put new grease on the gears. If you add wire to the machine and tension it to "3" (advertised), the welder will weld for like 5 seconds then stop feeding. If you remove the wire, and power off the machine and turn it back on, the machine feeds again.
I put my finger on the PTC1 and it got hot enough fast to burn me (oops), I know this is the function of this device, but how can you test them to be good? Are they just bad if you test them with a open circuit while cold? or can they degrade?
It still feeds with no pressure on the wheel for a few clicks of the trigger. I saw some replace the Transistors, I didnt think it was needed as the welder still feeds, just not for long.
I just wanted to make sure Im going in the right direction!
Thanks.
