The machine needs to be placed in a well-
ventilated area ensuring that air vents are not
covered.
4.2 For TIG Welding
Connect the dinse connector of the supplied
TIG torch to the machine’s negative output
terminal
6
. The gas hose must be firmly
connected to the gas output connector
7
and the contactor control must be connected
to the contactor control socket on the
machine
8
. The work return lead should be
connected to the positive (+) output terminal.
The amperage for welding can be adjusted
by turning the weld current adjustment
knob
5
. The duration of the post flow gas
can be adjusted by turning the post flow gas
adjustment knob (a longer post flow gas will
result in better protection for the weld pool
and TIG tungsten).
Connecting the shielding gas.
Fit the supplied shielding gas regulator to the
appropriate shielding gas cylinder ensuring
safety steps are followed as outlined on page 6
of this manual.
Open the cylinder and set the required gas
flow using the pressure adjustment knob on the
regulator.
4.3 TIG Welding Operation
The MagMate TIG 150 or 200 is fitted with a
High Frequency (HF) start mode. The arc would
be initiated by keeping a distance of 2-4 mm
between the workpiece and the tungsten. The
HF will be initiated by depressing the contactor
switch. Once the arc is initiated, the HF will
automatically turn off.
4.3.1 For Direct current (DC)
TIG Welding
Select the correct size and type of
non-consumable tungsten and shielding gas for
the application.
For (DC-) (most commonly used polarity)
connect the TIG torch to the negative dinse
plug connector and the work return lead to the
positive dinse plug connector.
