Changing Consumable Parts

Remove Consumables

Check the consumable parts daily for wear before cutting. Before removing consumables, bring the torch to the
edge of the cutting table, with the torch lifter raised to its highest point to prevent the consumables from
dropping into the water of the water table.

However, DO NOT CHANGE CONSUMABLE PARTS WHILE IN THE IDLE MODE! Always
disconnect power to the power supply before inspecting or changing torch consumable parts.
