Section 3
A more detailed note of explanation about the Pilot Arc function: The pilot arc is
intended to provide continuous arc when the arc is first started to establish con-
tinuity and then shuts off after the arc transfer to the work piece when actual
cutting begins. It automatically re-engages when the arc is lost while the trigger
is being held. The re-engagement feature is intended for use on expanded metal/
grating and for cutting in circumstances where the arc is likely to be lost. It pre-
vents the user from having to manually re-fire the trigger. Do not use this feature
excessively or consumable and torch life will be shortened as the consumable
itself carries the arc. Do not fire continuously without the intention to cut. This
arc is not designed to cut. Always keep work clamp attached directly to the part
being cut. If only shallow cutting or light scoring of the metal is noticed, check
work clamp connection before continuing cutting operations. This is a symptom
of the pilot arc being constantly engaged without arc transfer, and almost al-
ways indicates a work clamp or connection problem. It can also indicate a prob-
lem with point gap setting. As a generally good practice, only fire the torch
briefly when setting the air pressure. Use the post flow timer feature to help ad-
just the correct pressure while flowing by increasing post flow time to the maxi-
mum setting. Do not continue to hold the torch trigger so the air will flow.
NOTICE: To cut on thin metal with lower amperages, you should change nozzles to
ones a smaller diameter orifice. You should order nozzles/tips with smaller orifices
that match your amp output from Everlast and other online sources if lower amp cut-
ting (< 40A) is desired. The stock consumables supplied with the unit are designed to
offer the best cut quality with 40-50 amps service at recommended air pressure.
(Nozzle orifice dimension is marked on the side in mm.) The standard supplied nozzle/
tip diameter may be 1.0 or .9 mm. Lowering the air pressure with a larger orifice noz-
zles to attempt to cut thin gauges of metal is not recommended. Lower the amperage
and maintain the recommended air pressure settings with nozzles that have smaller
nozzles for best cut quality and speed on thin metals. If you are not sure about what
size you need, contact Everlast. As a general rule, for each 10 amp unit of drop in am-
perage below 40 amps, you will want to reduce orifice diameter by .1 mm. Not all orifice
diameters and configurations are available from Evelast, but most can be bought from
other sources. To achieve successful cutting while cutting on 120V, you will have to
purchase smaller consumables. The consumable provided are intended to cut best on
240V. Additional, smaller diameter consumables may be purchased from Everlast, local
Trafimet retailers or other onine after market suppliers of S-45 consumables.
