Collet Body
Collet bodies screw into the TIG torch
and accommodate various size tung-
sten and their respective collet.
Size
1.6mm I/D
2.4mm I/D
Collets
Directly hold the tungsten in place
when you tighten the back cap and
create the electrical contact necessary
for good current transfer.

Back Caps
Apply pressure to the back end of the
collet to force it against the collet body.
This pressure holds the tungsten in
place and seals the torch head from
the atmosphere. Back caps simply twist
into the back of the torch to prevent the
tungsten from slipping.
Basic TIG Torch
The components parts of a WP-17V TIG torch, collet bodies and
collets are sized to match the electrode and should be fitted in
matched sets.

Gas
When using the TIG function with
the Inverter welder, you will require
a gas regulator (flowmeter & tank
gauge) connected to a bottle of inert
gas. We recommend that you check
for gas leakage prior to operation
of your machine and you close the
cylinder valve when the machine is
not in use.

Tungsten Electrode Preparation
Sharpening tungsten is very important for a nice fine arc strike.
Grind lengthwise, not radial
Preparation
Before welding ensure that:
•
If you have not TIG welded before we recommend consulting
external information and practicing first.
•
You have read and understand the safety section of this
manual.
•
There is sufficient ventilation, particularly at the front and rear
of the unit.
•
You have an adequate fire-fighting devices on hand.
WARNING!:
ENSURE ALL OIL, PETROL AND
FLAMMABLE CONTAINERS HAVE BEEN REMOVED
FROM WELDING AREA.

Tungsten Electrode
2% Cerium Tungsten (grey tipped).This
tungsten requires less amperage to
start so it is recommended for thinner
metals, it can be used to weld every
type of metal
