IK-12 max3 is a semi-automatic cutting machine, which can be used not only for gas cutting, but also for plasma cutting and welding. A large selection of accessories are available to be used combined to the main components (main body, torch set and rail) according to the application. Our double cone stepless transmission system provides a stable rotational speed range, avoiding problems due to heating and unstable voltage. Machine also has a high thermal insulation performance due to the use of heat-resistant grease and Teflon wiring. S-type is a mechanism for switching between the low speed and high speed. The running speed covers from 80 to 2400mm/min (50Hz), and from 100 to 3000mm / min (60Hz).
