Hi all,
Hope you can shed light on this problem. Welder is a Draper 1302T which is about 6 years old and done a bit of work (about 40kg wire through it and mainly on 0.8 wire and high power). The wire feed was getting a bit sticky so I replaced the liner (plastic) with a length of curtain wire as someone sugested on this forum. I found I was able to reduce the roller tension a lot using the pinch test. I also found the plastic spool mounting cracked and replaced it with an alluminium one I got made.
Now when I run the welder the wire speed setting has gone down from about no. 5 to 0 to 2 with 0.8 wire on 3mm + steel power setting high 1 and 2. If I try to weld anything thinner then I cannot use the lower power settings as the wire feed is too fast (min 1 and 2). It has never been much good at the lower power settings even on 0.6 wire but is worse now.
I have not yet tried it with 0.6mm wire since fitting the liner.
On the 0 setting the wire runs at a fair speed, turning up the speed dial and the speed increases in propotion. I have looked at the circuit board and there is no trimmer pot. The handbook says the board is CS320 Draper part number 035093006.
How can I reduce the wire speed?
Will it improve using 0.6 wire?
Can I fit a resistor in the wire from the control board to the motor and if so what size and rateing?
Do I need to go back to the original liner.
Thanks in advance
Chris
