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?
I found this from Chris in another post..

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 notice more significant issue seems J5 belting system can't hold higher weight, I'm tested 1.8kg (near 4lbs) the J1-J4 can hold without issue, but J5 will belting system jump step and cause J5 turn down. It mean, my AR3 can't hold 4lbs (Maybe because I assemble badly?)
Overall I feel at J5, current belting system design is biggest bottle neck and cause lower payload. if it can change to chain/gear system will be nice?
Hi Dan, I'm based in Austin & was just about to ask the exact same question.
