(NOT INCLUDED)
STANDARD INSLUATOR
CERAMIC CUP
Select the insulator based on if you wish to
use a quartz or ceramic cup. The kit supplied
stubby insulator is used for quartz cups, and
the insulator supplied with your torch is used
for ceramic cups.
Before beginning assembly it is important to first identify the correct parts in the kit you will need to use.
If you’re using a size 17, 18, or 26 you would choose the longer gas lens. The 9 or 20 size torch uses the
shorter gas lens.
If you’re using a size 17, 18, or 26 you would choose the longer wedge collet. The 9 or 20 size torch uses
the shorter wedge collet. You will need to match the tungsten size you’re using to the corresponding gas
lens and collet size. Each gas lens and wedge collet are marked for their tungsten size.
You will need to match the tungsten size to the hole diameter of the filter screen located in the gas cup.
Select the correct filter size to match your chosen gas cup size, and thread the filter through your chosen
tungsten size to ensure it matches. All cups come ready for 2.4mm tungsten diameter.
TORCH TYPE/SIZE & TUNGSTEN SIZE

CUP TYPE
Ensure you have selected the correct type of back cap to match your torch type based on the location of
the rubber o-ring gasket. If the o-ring is located on the black plastic, it is meant for size 17, 18 & 20 type
torches. If the o-ring is located on the brass portion it is meant for 9 or 20 size torches. Choose the length
of back cap based on the available weld space for your torch. If you choose the shorter back caps you will
need to shorten your tungsten electrodes.

To remove a mesh filter screen from your ceramic or quartz cup,
insert the longer, thinner side of the filter screen installation tool
into the side of the cup that attaches to the torch and push out
the filter screen.
To insert a new mesh filter screen into your ceramic or quartz
cup, place the filter screen on the shorter, thicker side of the
filter screen installation tool and push it into the opening of the
cup until the cup is flush with the circular part of the installation
tool the filter screen.

Screw the collet body into the torch head.
Fasten securely. Ensure that the o-ring is in
the correct position on the collet body.
Insert the wedge collet into the
small end of the gas lens.

HEAD
Insert the tungsten electrode into
the collet/stubby gas lens.
Screw the back cap into the torch
head, don’t tighten all of the way.
Screw the ceramic cup or slide the
quartz cup onto the stubby gas lens.
*DO NOT OVER TIGHTEN CERAMIC*
Adjust the tungsten to the desired length, then tighten the back cap.
