13. Sequence Of Operation For 25, 40, 50, 55, 80, And 100 Ampere Torches

Inspect shield cup, tip, and electrode for wear be-

fore cutting or whenever cutting speed has been

significantly reduced (see Section 17). Do not op-

erate torch without a tip or electrode in place.

NOTICE − Do not clean torch by hitting it against a hard

surface. Hitting hard surfaces can damage torch parts

and stop proper operation.

electrode and torch life. Put a continuous piece of sheet

metal under the fence to prevent pilot arc from cycling On

and Off. Avoid constant starting and restarting of arc.
