A LOOSE OR OVERTIGHTENED ELECTRODE CAN CAUSE DAMAGE TO THE
TORCH
If you do not correctly install and tighten the electrode, torch damage can
occur.
A tool is necessary to correctly install and tighten the torch electrode. Do not
use your hands. Hypertherm® recommends tightening the
electrode to a torque value of 2.3 N∙m – 2.8 N∙m (20 lbf∙in – 25 lbf∙in).
