OPERATORS PENDANT CONNECTION
The Model 415 is supplied (standard) to operate Weld Heads and the Pendant up to 70 feet (21
meters) from the Power Supply Cabinet. The Pendant includes a built in 20 foot (7 meters)
connection cable and attaches to a 50 foot (15.2 meters) standard Pendant Extension cable. For
ease of operation the Pendant can be connected directly to the Power Supply without the use of
the 50 foot (15.2 meters) Extension Cable.
Perform the following steps for the installation of the Pendant:
1.
Connect the Power Supply end of the 50 foot Pendant Extension Cable to the Model 415
Pendant Connector on the Electrical - I/O Connect Panel (see Figure 1, Item 6).
NOTE
All Weld Head and Power Supply Electrical Connectors are keyed for proper mating. Insure
that correct connectors are being used before attempting to install.
2.
Connect the Cable on the Pendant to the Extension Cable. (see Figure 1, Item 5, 6).
3.6
INERT GAS CONNECTION
The Model 415 requires for operation, an inert gas source, gas pressure regulator and gas flow
meter. These items are not furnished with the Model 415 and must be supplied by the user.
1.
Mount a single or double stage pressure regulator (set pressure Maximum 90 PSI) and Flow
Meter (able to regulate between 5 and 100 CFH) on an appropriate gas supply.
2.
The Model 415 is supplied with a 15 foot Input Gas Hose with a standard 5/8 male NPS
fitting on one end and a Bulkhead gas fitting on the other end.
3.
Connect the Input Gas Hose to the Flow meter (NPS) and to the BULKHEAD Input Gas
Fitting at the rear of the Model 415 (see Figure 1, Item 14).
NOTE
Automatic GTAW welding systems are very sensitive to gas quality (purity). The hose
supplied with the Model 415 is specifically selected for its ability not to trap moisture or
aspirate oxygen. Rubber, Tygon or most other types of gas hoses are not recommended for
use with the Model 415 and will eventually cause welding problems.
CAUTION
The M-415 arc gas solenoid valve is rated at 90 PSI (620 KPa) maximum pressure, DO NOT
EXCEED THIS RATING.
