Plasma Cutting Operation Warnings And Safety Information - Everlast PowerPlasma i Series Operator's Manual

Component Identification and Explanation
Plasma Cutter Function Important Information and Warnings:
DANGER! Never touch any of the bare portions of the torch power connectors, fuse, consumables or torch control while the
unit is switched on and torch is connected. Severe injury or death may occur if the torch trigger is accidentally activated or
becomes damaged.
WARNING! Do not use sun glasses or non cutting glasses to protect the eyes. Use at least a shade 8 for plasma cutting
where the arc is clearly visible. Never use less than a shade 5, and only use that for situations where the arc is not visible.
Do not use cutting shades rated only for Infrared use, such as those designed for Oxy-Fuel use. These usually do not offer
sufficient UV protection unless stated otherwise.
CAUTION! Keep the torch switch isolated and the consumables in place on the torch while the unit is switched on. Turn the
unit off to change consumables. Do not remove the trigger safety guard or attempt to defeat its operation in any manner. If
the trigger safety becomes damaged, replace immediately. Turn the machine off to replace the consumables.
CAUTION! For most cutting applications, use the "Lock-Off" Setting. Do not use "Lock-On" unless you are familiar with its
operation. Attempting to use this setting without being thoroughly familiar with this setting may cause a panic stop and can
result in severe burns and injury. "Lock-On" is for only experienced users that intend to make long cuts. If you use "Lock-
On", remember that the arc will stay on until the trigger is cycled again. Lock-Off is the simplest operation with a "press and
hold" operation. "Lock-On" requires a "pull and release" to start the arc. The arc will continue without the trigger being held.
The cut will continue until the trigger is pulled and released once again.
WARNING! Do not submerge the work clamp in water, particularly for use on CNC plasma tables. Always connect the clamp
directly when possible, but the clamp should never be submerged in water, or the water may siphon down the cable through
capillary action and run into the DINSE connector or the machine. If the work clamp cannot be safely attached to the work
without submerging it, either lower the water level of the table, or use a thick copper jumper wire direct to the work clamp
which is attached directly to the work clamp.
WARNING! A poor work clamp connection may cause faulty cutting, loss of cutting power, or excessive pilot arc engagement.
The Pilot arc is not designed for continuous run and the length of its time on should be limited as much as possible. Even
though the fuse may not blow if the pilot arc is left on continuously or is being used excessively, the fuse holder may overheat
or become damaged. If poor cutting is experienced, with minimal penetration into the cut, the pilot arc may be staying en-
gaged. Check the work clamp and cable for proper connection. If necessary, change the work clamp if the copper cable and
strap have burned or looks corroded.
If the pilot arc does not appear to transfer, particularly when being used on CNC cut tables stop immediately, and investigate
the cause. Usually this is a result of a poor work clamp connection, or too high of a cut height. Do not allow the pilot arc to
remain on continuously. To do so will increase consumable wear greatly, or overheat the pilot arc circuit.
The design of the blow back start may cause a slight delay in the arc as the air pressure must built inside the torch tubing and
head to create the pressure needed to force the electrode off the nozzle seat. This may take up to a second, especially when
using longer torches or marginal air supply systems. Restarting the arc in tip saver mode requires retriggering the torch. If
the torch does not light after 3 seconds, let go of the trigger and press it again. If the start or arc is erratic check nozzle and
electrode for tightness and wear.
STOP!
