Pilot Arc Function The BTC600DP 13 plasma cutter has the function of pilot arc. It is a high frequency non-touch arc start mode. The torch head does not need to touch the metal plate. Adjustable PA function added, extended pilot arc hold time, reduce power consumption during uninterrupted work, reduce electrode burning and extend service life Digital Display The display centrally displays parameters such as air pressure, voltage and current, which allows users to understand the status of the equipment in real time and adjust operations in a timely manner, improving operational efficiency. If the plasma cutter cannot work, the display comes with an error code system, which makes it easier to identify problems 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 via the air regulator (air pressure cannot be adjusted automatically). An air filter is installed on the back of the machine, equipped with a quick connect 1/4 NPT air connector, ready for use directly out of the box. Once connected to an air compressor, the recommended air pressure should be less than 70 PSI, with a flow rate of 250 litres per minute [Cutting Thickness] The HF pilot arc plasma cutter has automatic sensing function for input voltages of 110V and 220V, 60% single-phase work cycle. Recommended for cutting thicknesses up to 12mm at 35A at 110V at 50PSI, 18mm at 60A at 220V at 65PSI. Circuit breaker specifications require 40A unit for 110V operation and 30A unit for 220V This versatile plasma cutter is ideal for use on materials such as stainless steel, alloy steel, mild steel, copper, aluminum, etc [PT/2T/4T/PA Function]: Post-flow cooling time which varies from 3 to 15 seconds extends the torch head and the life of consumables. The 2T mode on the plasma cutter provides a semi-automatic control torch trigger, while the 4T mode allows the automatic trigger, free your finger. PA set the time for the pilot arc. This bestarc BTC600DP 13GEN plasma cutter also includes mesh cutting mode to solve the arc breaking problem when cutting mesh, Manufacturer: bestarc
