In operation, SCR acts conducting when a pulse is provided to the gate. It operates at in either on or off state. Once the gate is triggered with the pulse, SCR goes to the on state and keep conducting until the forward current become less than a threshold known as holding current.SCR is a power device and most of the times it is used in applications where high currents and voltages are involved. The most used SCR application is controlling (rectifying) alternating currents.With the help of oil free compressed air delivery at 5.5 bar & electricity, Thyristor based plasma cutting machine cuts all metals like Stainless Steel, Mild Steel, Copper, Brass, Aluminium, Inconel, Monel, Titanium, Nickel, Chorme, Bronze, Galvanised Steel, Heated Steel, Wear Plates, Castings.
