All our R-Tech Plasma Cutters feature automatic arc starting - This comes in 2 different styles.
Contact HF starting as found on our P30C & PC31 Plasma Cutters, uses HF to jump the gap between the torch tip and workpiece when the trigger is pressed and tip is held on work surface.
Once the arc has started the HF turns off automatically. This will start on lightly painted and rusty surfaces with ease. If the surface has a very heavy coat of paint, you may need to grind this of if cutting is difficult to start.
Pilot ARC starting as found on our P51D and I-Cut100 start a pilot arc. A 1-inch blue flame comes from end of torch when trigger is pressed - when this arc touches the workpiece, the machine senses a circuit and then turns on the main cutting power - The pilot arc is very strong and can cut 2mm into steel so this is ideal for starting on very painted surfaces.
Pilot ARC re-starting as found on our P51D and I-Cut100 machines is where the machine senses no more metal to cut, so re-establishes the pilot arc until more metal is sensed, ideal for cutting mesh etc.
