CONNECTIONS FOR TIG (GTAW) WELDING

TIG TORCH CONNECTION

Refer to Included Equipment in the Operation Section
of this manual for TIG welding equipment which is
included with the Square Wave TIG 175.
A TIG welding torch with cable and connector is sup-
plied with the welder. Turn the Power Switch "OFF".

Electrode/Gas Output Receptacle on the front of the
welder and turn it clockwise until it is tight. This is a
quick connect terminal and also provides the gas con-
nection for the shielding gas to the torch.
WARNING
To avoid receiving a high frequency shock, keep the
TIG torch and cables in good condition.
__________________________________________

WORK CABLE CONNECTION

A work cable with attached work clamp is factory con-
nected to the Square Wave TIG 175. To minimize high
frequency interference, refer to Machine Grounding
and High Frequency Interference Protection section
of this manual for the proper procedure on grounding
the work clamp and work piece.

SHIELDING GAS CONNECTION

An adjustable gas pressure regulator and flow gage is
supplied with the Square Wave TIG 175. Obtain the
necessary inert shielding gas (usually argon).
Connect the cylinder of gas with the pressure regulator
and flow gage. Install the gas hose between the regu-
lator and gas inlet (located on the rear of the welder).
The gas inlet has a 5/16-18 right hand female thread;
CGA #032.
WARNING
CYLINDER could explode
if damaged.
•Keep cylinder upright and chained
to a support.
•Keep cylinder away from areas where it could be
damaged.
•Never allow the torch to touch the cylinder.
•Keep cylinder away from live electrical circuits.
•Maximum inlet pressure 150 psi.
___________________________________________
The optional undercarriage features a pivoting platform
that simplifies loading and unloading of gas cylinders.
A cylinder is loaded by leaning it slightly sideways and
rolling it toward the platform. The cylinder's weight will
push the platform downward against the floor, forming
a ramp. At this point, the cylinder may be rolled up the
platform into its final position. Secure the cylinder in
place with the provided chain. Unload by following
these steps in reverse.
