I assembled my cross fire pro and I need to know if the contact plates inside the z axis that the IHS wires lead to are designed to move freely, I know the bottom one is stationary but is the top one designed to move freely or is it supposed to be tight and only make contact when the machine touches the bottom ? Please help
The bottom contact is attached to the z-axis lead nut and moves up and down based on the z-axis motor. The top contact is mounted to the torch holder mount and in normal operation rides on the bottom contact, moving the torch up and down with the motion of the z motor. The only time the contacts should be separated or open is during IHS phase of a cut and the z motor drives down until the torch contacts the metal, the z axis will continue down a short way causing the contacts to open signalling firecontrol that the torch is in contact with the metal at which point the z axis motor will drive upward until the two contacts touch and close the circuit signalling firecontrol to zero out the z axis.
In other words, the top contact should be able to float freely, rolling on the z-axis rails. The only time the top contact should be unable to float is if the z axis is all the way up, trapping the top contact/torch mount against the top of the z axis assembly.
Yes i understand, , reason being is that my torch is not firing at all so I thought this was the problem now I got to put it back where it was floating freely, I have got my torch to fire but never when on a program
I’m assuming you are getting the Torch is moving before firing warning in Firecontrol. All machines have different requirements for pierce delay based on the machine. My HF Titanium 45 won’t light unless I use a .7 second pierce delay minimum. So you might need to keep pushing your delay up and see if that works. If you get up over a full second and it still won’t light then I’d start looking at other factors, such as sufficient air, good consumables, torch assembled correctly, among lots of other factors.
There are plenty of knowledge people here and we’ll help you get it figured out.
I have found for my set up, anything less than 0.64 seconds will potentially not have time for the torch to fire. But one time I though I was setting 0.65 seconds and my brain was seeing 0.65 seconds but I was actually inputting 0.065 seconds.
Inside that cable are two wires. One is connected to the outside metal part of the connector and the other wire is connected to the metal on the inside of the connector. To short it, you can put a piece of wire or a paper clip inside the connector and touch it to the metal part on the outside.
