FIREPOWER TIG 140 AC/DC INSTALLATION/SETUP
1. Positive Welding Terminal
Positive Welding Terminal 2" (50mm) Heavy Duty Bayonet Dinse. Welding current flows from the Power
Source terminals. It is essential, however, that the male plug is inserted and turned securely to achieve a
sound electrical connection.
2. 8 Pin Control Socket
The 8 pin receptacle is used to connect a trigger switch or remote control to the welding Power Source circuitry:
To make connections, align keyway, insert plug, and rotate threaded collar fully clockwise. The socket information
is included in the event the supplied cable is not suitable and it is necessary to wire a plug or cable to interface
with the 8 pin receptacle.
NOTE
When not using a Remote, disconnect any remote control device or it may limit the preview and actual
output current range.

3. Negative Welding Terminal
Negative Welding Terminal 2" (50 mm) Dinse. Welding current flows from the Power Source terminals. It is
essential, however, that the male plug is inserted and turned securely to achieve a sound electrical connection
CAUTION
Loose welding terminal connections can cause overheating and result in the male plug being fused in the
terminal.
4. Shielding Gas Outlet
The Shielding Gas Outlet located on the front panel is a 5/8-18 UNF female gas fitting and is utilized for the
connection of a suitable TIG Torch.
5. Power ON Indicator
The POWER ON indicator illuminates when the ON/OFF switch (20) is in the ON position and the correct mains
voltage is present.
6. Fault Indicator (Thermal Overload or Primary Circuit Overcurrent)
1. Thermal Overload
This is due to the duty cycle of the power source being exceeded. Once the power source cools sufficiently
it will automatically reset and the Fault Indicator and Err 000 will go off and the power source is then able
to continue welding. During the time of cooling the power source should remain ON such that the fan
continues to operate allowing the unit to cool sufficiently. If after 30 minutes with the fan running the Fault
Indicator has not gone OFF then have an Accredited Firepower Service Provider check the power source.
