  • Page 112 Some amount of dross is inevitable when plasma cutting, but you can minimise it by adjusting your settings to your specific application. Excess dross appears on the top edge of both pieces of the plate when the torch height is too low. To reduce this, adjust the torch until the dross is minimised.
