Q) We have old valiant machine and brand new dragon machine, the valiant has old ST THCEX 02 model THC.  We find the new dragon machine THC ST-THCEX 03 model more easy to use and better responding. Is it possible to buy a new THC and replace the old model?

A) Yes, it is possible to replace the old model THC with the new model ST-THCEX 03. The replacement is very simple just have to unplug the old THC and remove it from the cross beam fix the new THC in place of the old THC and plug back the cable to the new THC. No modification on the machine electrical or holders required.
