The Powermax45 is available with a hand torch, which has a trigger switch for hand cutting and is ergonomically designed for the average human hand, and also a machine torch which is mounted on an industry standard barrel (1-3/8" diameter) and requires some sort of remote trigger (no switch is included). Internally both of these torches are similar, and the consumables are interchangeable between them. A hand torch can be used in a mechanized application, and these torches quick disconnect from the power supply with no tools.
As far as interface signals to a cnc machine. There are typically 3 sets of signals which involve 6 wires.
1. Arc voltage feedback is used to control the torch to work distance of the torch. The Powermax45 has an analog DC voltage output available on the rear panel interface receptacle that is 1/50th of the actual arc voltage. This ration is used by many torch height control manufacturers to track torch arc length. If raw, ful voltage is required, you would have to remove the cover from the Powermax (2 screws) and follow the directions in the Hypertherm manual to make these internal connections. The Raw DC voltage can reach voltage levels of arount 250 VDC, a voltage level that exceeds CSA and CE safety regulations, so this voltage is not vaialble on the rear panel connector.
2. Arc transfer. These connections are also available on the rear panel connector. When the plasma arc is activated and electrical current starts to flow from the torch to the plate...a set of relay contacts closes inside the Powermax unit. This signal is used to indicate to the cnc that the plasma arc in on.
3. Plasma start. There are connections for plasma start on the rear panel connector....this signal is only functional if the machine torch is connected to the Powermax unit. If the hand torch is installed the start input of the rear panel is automatically disabled for safety reasons, as the hand torch has a trigger switch, and it could be dangereouse to a torch operator if a remote start was allowed for a hand torch. If you must use a hand torch for mechanized use, then the torch trigger must be bypassed internally inside the power supply, quite easy to do. The plasma starts when the cnc sends a contact closure to the plasma start input.
These signals are standard on the Hypertherm system, you can eaither make your own interface cable or you can purchase the hyperthem cable (I do not know the price, but if you need it I will look up the part no. and price) .
The Hypertherm unit is known for its reliability, and its consumable life. If you compare specs with the T-D unit you will see both a higher output duty cycle and killowatt rating....hese are two very important factors for best plasma system performance. The Hypertherm units are completely built in Hanover, NH, USA by owner/employees of Hypertherm.
