I am interested in welding with a push/pull gun, but I fear it will exceed designed capacity. Could I simply increase the gear ratios to increase load capacity (and correct in the software) or is there more that is needed?
Thank you, you may be able to push 7 or 8 lbs going slow and limiting the torque or extension on joint 3 but I don't believe you will get all the way to 10-15lb range. Its Joint3 that gives up when its overloaded. It may be possible to go with a higher ratio gearbox on 3, currently its 50:1 I'll have to look and see if they have a 100:1 in that frame size.
I found this from Chris in another post..
