Terminal Strip Connections
Terminal strip TS2 located behind the hinged control panel on the front of the power source supplies
To gain access to the terminal strips simply remote the #10 sheet metal screws from the perimeter of the welder nameplate. Tilt panel forward so it rests in a horizontal position. See Table showing Front View of
Machine and Circuit Protection
The power source is thermostatically protected with proximity thermostats against overload or insufficient cooling. One thermostat is located on the nose of the center bottom primary coil and a second thermostat is attached to the lead connection the secondaries. Both thermostats are connected in series with
The fan will continue to run. The secondary thermo- stat will open either with an excessive overload or insufficient cooling. The output will be zero and the amber protection light will be off.
115VAC GFCI RECEPTACLE
(Codes 11038 and higher)
The GFCI receptacle is located near the output studs and protected by a 15 amp circuit breaker.
Testing the GFCI Receptacle
a.) Turn the welder ON. Press the reset button fully. Plug a lamp or radio into the GFCI (and leave it plugged in) to verify that the power is ON. If there is no power, go to Troubleshooting.
b)Press the TEST button in order to trip the device.This should stop the flow of electricity, mak- ing the lamp or radio shut OFF. Note that the RESET button will pop out. If the power stays on, go to troubleshooting. If the power goes OFF, the GFCI is working properly. To restore power, press the RESET button.
c)Press the TEST button (then RESET button) every month to assure proper operation.
NOTE:
The GFCI receptacle is in a 115v circuit where the neutral is floating with respect to ground. Consequently if a GFCI tester is plugged into the GFCI receptacle, the tester will show that there is an "open ground". This indication of an "open ground" is normal and the GFCI will function properly in the event of a ground fault current as the GFCI is designed to do.
