[Pilot Arc Function]: BTC650DP 7th plasma cutter has the pilot arc function. It is a high frequency non-touch arc starting mode. The torch head does not need to touch the metal plate. Added PA adjustable function, extended pilot arc maintenance time, reduce energy consumption in non cutting work, reduce electrode burning, and extend service life[Cutting Thickness]: HF pilot arc plasma cutter boasts an automatic detection feature for input voltages of both 110V and 220V, 60% duty cycle single phase. The maximum cutting thickness of bestarc 65A plasma cutter can reach up to 3/4" @65A 220V 70PSI, while ideal clean cut at 1/2" @35A 110V 55PSI. The circuit breaker specifications require a 60A unit for 110V operation and a 40A unit for 220V. This versatile plasma cutter is ideal for use on materials including stainless steel, alloy steel, mild steel, copper, aluminum, etc[Air Sensor Technology]: The air sensor built into the machine displays the air pressure on the front panel of the machine. Users can adjust the air pressure manually through the air regulator (air pressure cannot be automatically adjusted). An air filter is installed at the back of the machine, equipped with a quick-connect 1/4 NPT air connector, ready for use right out of the box. Once connected to an air compressor, the recommended air pressure should be within 70 PSI, with a flow rate of 250 liters per minute[Digital Screen Display]: The screen centrally display parameters such as air pressure, voltage, and current, allowing users to understand the equipment status in real-time and adjust operations in a timely manner, improving operational efficiency. If plasma cutter cannot work, the screen comes with an error code system, making it easy to find out the problems[PT/2T/4T/PA Function]: Post time function, with an adjustment range of 3-15 seconds. Adjust the cooling time of the torch head to extend the service life of consumables. Generally speaking, we recommend a cooling time of 4-8 seconds. 2T/4T automatic cutting release your finger. 2T is semi-automatic cutting control, and 4T is automatic cutting control. PA adjust the time for the pilot arc, longer seconds good at cutting mesh metal, short seconds is good to extend the life of consumables
