A: 1t is that the connecting machine can only press the horizontal joint terminal. The meaning of the connecting machine is that the machine is connected with the mold and can't be disassembled. So 1t can only press the horizontal small terminal and can't change the mold. If the head end connection is a straight terminal, it can not be pressed. The 1t terminal machine can't press single grain. It's not safe to press single grain. It's recommended to use 1.5T to press single grain. 1.5T power is larger than 1t, can press slightly larger or thicker terminals, can change all kinds of molds, only need to change the horizontal mold to press the joint and horizontal terminals, can press the joint and straight terminals for the straight mold, can press one loose terminal for the single mold, can press all kinds of flag terminals for the flag mold. In the long run, it is recommended to choose more than 1.5T.
