! The pilot arc starts immediately when trigger is pressed.
For 25 ampere torch, place tip on
edge of metal.
For 40, 50, 80 and 100 ampere
hand-held torches, place drag
shield on edge of metal, or allow
correct standoff distance −
approximately
1/8 in (3.2 mm).
! 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.
NOTICE − Having pilot arc turn On and Off repeatedly,
such as during the cutting of chain fence, will shorten tip,
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.
