What to do if the Over Temp Indicator is on in my Thermal Arc 201 TS Welding System?
If the duty cycle has been exceeded, reduce weld time and allow the power supply to cool. Also, check the thermostat wire connections. If the connection is properly inserted and the Over Temp Indicator is still on after a short-circuit thermostat, replace the control panel; otherwise, replace the thermostat.
Why is the weld output low on my Thermal Arc 201 TS Welding System?
If the input mains are at 230VAC and the output is limited to 125Amps, check the Front panel PCB3 J25 connector and the Main Power PCB1 J16 connector. If they are properly inserted, replace Control PCB2.
Why is the weld output high on my Thermal Arc 201 TS Welding System?
If the input is 115V and the output is near 160A, check whether it is shorted between pin1 and pin 3 on the IN JC connector on the main power board. If it is not, replace the control board.
What to do if the power indicator is ON but the fan doesn't run on my Thermal Arc Welding System?
First, check the fan for any obstructions. Next, verify whether the J12 connector on the main board PCB1 is plugged in properly, ensuring there is +24V±10% on pins 1 and 2 of the J12 connector. If both checks are okay, replace the fan.
What to do if there is no gas flow in Lift Tig / HF Tig Mode on my Thermal Arc Welding System?
First, make sure the process switch is functioning properly and set to Lift Tig or HF Tig mode. Next, ensure that pin3 and pin4 of the J12 connector on the main board PCB1 have +24V±10%. If these steps don't resolve the issue, replace the gas solenoid.
How to troubleshoot no HF in HF TIG mode on a Thermal Arc Welding System?
Ensure the process switch is functioning properly and set to HF TIG mode. Check the TIG torch switch for continuity. Also, inspect the wire harness on the 8-pin remote connection. If these are okay, measure 15VDC between pins 1 and 3 on (PCB1) J17 when the torch switch is depressed. Verify the HF arc starter wire connection. If the problem persists, replace the main power PCB1.
What to do if I cannot adjust the weld current on my Thermal Arc 201 TS Welding System?
Check the Control panel PCB 3 J26 connector and the Remote control PCB4 J27 connector to ensure they are properly inserted. Also, check the Current Control Potentiometer for an adjustment of 0 to 4.8vdc from Min to Max on Front Panel PCB3, where Pin1=Min, Pin2=Wiper, Pin3=Max. If the adjustment cannot be made correctly, replace Front Panel PCB3.
What to do if there is no open circuit voltage on my Thermal Arc Welding System?
First, check the process switch on the front panel to ensure it's functioning correctly. Then, check the Bus voltage on Main Power PCB1; it should read 385VDC. Turn off the power supply, remove Mains Power, and inspect the Input IGBTs and Output Diodes. If incorrect, replace the main power PCB1. If everything above checks out, replace control PCB2.
Why is the ON/OFF Indicator blinking on my Thermal Arc 201 TS Welding System?
Make sure the voltage between pin 1 and pin 2 of the J11 connector on the main power PCB1 is -24VDC±10%, and the voltage between pin 2 and 3 is +24VDC±10%. If the voltage is correct, replace the front panel PCB3. If the voltage is incorrect, disconnect the harness of the J11 connector and re-measure. If still incorrect, replace the Main Power PCB 1.
How to troubleshoot the ON/OFF switch when the power indicator is OFF on a Thermal Arc Welding System?
Check the power supply input. Check the ON/OFF switch continuity. Check the Inrush Resistor. Check the control PCB2 J8 connector and front panel PCB3 J24 connector to ensure they are properly inserted. Replace the front panel PCB3.
