How often should I check or change consumables?
Check consumables regularly for wear and change them out before they
are completely worn out. A good practice is to check consumables be-
fore turning the machine on each time you prepare to cut. It takes only a
few seconds and can save yourself a lot of extra effort later. Allowing the
consumables to wear until they quit working may damage torch related
components, creating a more costly repair. If the cut quality suddenly
deteriorates and begins to show greater than 5 degrees bevel, stop and
check the consumables for wear. Inspect the cut tip orifice for the tell-
tale signs of wear including deep pitting around the orifice and an egg
shaped hole. The electrode should be inspected for wear as well at this
time. The cap should be pulled off, along with the tip and the swirl ring.
The tip should be examined for wear. A slight pit is normal in the center
of the electrode. However, if the electrode tip is pitted around the center,
or the center has a deep hole in it, the tip is worn. The very center of the
electrode has a special insert made of hafnium. Hafnium is an expensive
and durable metal that is used for electrodes. If the hafnium insert is
wearing quickly, check for water or moisture getting into the system.
Also, periodically, with the unit turned off, check the spring action of the
electrode by removing the cup and tip and pushing your thumb or finger
down on the electrode. The electrode should depress slightly and spring
back quickly without a delay. If it does not, the torch head may need to
be disassembled, cleaned and lightly lubricated with di-electric grease.
In some cases the sealing O-rings may be broken or dirty causing stick-
ing. Replacement torch head kits are available if repair is not an option.
Sticking of the electrode like this causes starting issues. Most often this
condition occurs because of moisture and dirt that makes it way into the
system. Additionally, do not overtighten the electrode or overheat the
torch (by poor cutting techniques such as excessive piercing starts on
thick metal) or the electrode threads may gall in the torch head and
break off during removal. Do not under tighten it either. Use the sup-
plied wrench to tighten the electrode. Use your fingers only to tighten
with this wrench. Avoid using pliers to install and remove the consuma-
bles. This usually occurs on lower quality consumables (non-OEM) with
poor chrome plating, but can occur if OEM consumables are overtight-
ened.
When lowering amps to cut thinner material, you must change to smaller
orifice nozzle. Nozzles are offered in different sizes which are made for
different amp levels. See the torch parts page for amp range and size of
consumables. Everlast offers OEM size and configuration of consumables
originally supplied with the torch for replacements and do not offer all
configurations or sizes.
Everlast is not the manufacturer of the Innotec iPT series torches and
does not offer all possible consumable types available for the torch se-
ries. OEM suppliers of the Innotec iPT torches (local and online) offer
extended range of sizes and configurations. If drag cutting is desired,
shielded drag consumables are now available from several online
sources. .An orifice that is too large for the amps being used will result
in arc instability and a rough cut.
NOTICE:
What should the torch flame look like?
The torch flame angle can tell you if you are cutting at the correct
speed or not. Take a look at the examples below to help you deter-
mine if you are cutting at the correct speed.
