The T80M is the machine torch for the 1250. It is available with a bunch of different lead lengths. It is 1-3/8" (35 mm) diameter on the brass mounting barrel. The barrel has a 32 pitch rack gear attached...which is a standard diameter and type of mount for mechanized oxy-fuel torches. Most remove the rack gear if they don't want it. The gear is brazed on the brass barrel....but is relatively easy to remove. There was discussion on our manual systems product team about making the rack gear more easily removeable by attaching it with screws.....but I'm not sure if this has yet been implemented. Standard oxy fuel torch mounts have a hand adjusting knob with a pinion gear that allows you to adjust the torch height. The same consumables fit both hand and machine torches....although if you are not drag cutting...you should use the machine shields as they have a smooth face and have less of a propensity for acumulating slag.
