Lift-Arc™ start provides TIG arc starting without the use of high frequency.
Adaptive Hot Start™ for Stick arc starts automatically increases the output amperage at the start of a weld should the start require it. Prevents the electrode from sticking and creating an inclusion.
Superior Stick arc performance even on the difficult-to-run electrodes like E6010.
Thermal overload protection prevents machine damage if the duty cycle is exceeded or airflow is blocked.
