the later YS-GIRTH WELDER models).
NOTE: The GIRTH WELDER master control is powered by 220V/1ph VAC, please check for first time
operation.
CAUTION: After switching off the inverter, please wait for at least 3 minutes before switching it on again.
Quick repetitions to switch the inverter on and off could damage the inverter due to the residual voltage.
Please refer to the inverter manual for details.
4.6 WELDING
1. In a rapid, succession turn the switch towards the left or right (depending on welding direction), press
the ‘START’ in the NA-3 power source and finally turn the switch of the power supply unit NA-3 to the
position “auto”.
2. Monitor the voltage and amperage for welding and forward speed to ensure a good weld bead.
3. When finished welding, press the “OFF” button on the main control panel of the BGW-5000
4. For safety , press the “OFF” of the feeder NA-3.
NOTE: For models with electric flux valve option, the flux would feed automatically when the wire touches
the work when the operator presses “inch down” to feed wire prior welding.
NOTE:
* For safety reasons, please power off the system before disconnecting any of the control cables to the
master control.
* In order to increase the consumed life of the flux belt mechanism, the user is recommended to extend the
support guide wheels as the means of support when the GIRTH WELDER is not welding (flux belt must be
firmly in contact with the shell plate during welding operation for flux recovery).
* Excessive suction force would prohibit flux feeding during the welding operation; adjust the vacuum hose
valve if necessary.
4.6.7 If the machine is going to weld in the direction opposite of what it was previously set up for, simply shut
down the manual hose valve at one side and open the hose valve at the other side.
