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 PRO.
A TIG welding torch with cable and connector is sup- plied with the welder. Turn the Power Switch “OFF”. Connect the torch cable quick connect plug into the
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 PRO. To minimize high frequency interference, refer to Machine
Grounding and High Frequency Interference Protection section of this manual for the proper pro- cedure on grounding the work clamp and work piece.
SHIELDING GAS CONNECTION
Obtain the necessary inert shielding gas (usually argon). Connect a cylinder of gas with a pressure reg- ulator and flow gage. Install a gas hose between the regulator and gas inlet (located on the rear of the welder). The gas inlet has a
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.
