GENERAL DESCRIPTION
THANK YOU! You had options for other CNC machines and you chose LOTOS Supreme
CUT60D Plasma Cutter. We appreciate you as a customer and hope that you will enjoy
years of use from your plasma cutter.
Congratulations for your purchase.
The new, redesigned LOTOS Supreme CUT series is a non-high frequency start
machine. The “blow-back” type start that is used is generally safe for use in CNC
applications and is ideal for general use. Blow-back type start involves a rearward
movement of the electrode within the torch head when forced by the air pressure.
When air pressure is applied the movement of the electrode off its seated position
against the inner surface of the circuit grounded nozzle creates a spark, energizing the
plasma stream. With this machine’s start type and pilot arc design, you are able to cut
on any metal surface without having to contact to strike an arc which is ideal for cutting
items like expanded metal or uneven surfaces. This Cutting machine has a wide range
of uses which is suitable for cutting: stainless steel, alloy steel, mild steel, copper and
other color metal materials.
There are several other key features on the Supreme Cut series:
➢
With the reliable Blow-Back non-high frequency start, the LOTOS Supreme
CUT60D is suitable for CNC application meaning there will be no interference to
