Why is the alarm lamp on the front panel of my CANAWELD TIG AC DC 201 pulse D Welding System on?
- S
  Sabrina EllisonAug 18, 2025
  The alarm lamp might be on due to several reasons: * Overheat protection: Reduce the welding current output. * Working time too long: Reduce the duty cycle and work intermittently. * Over-voltage or low-voltage protection: Use a stable power supply. * Too many machines using the power supply simultaneously: Reduce the number of machines in use. * Over-current protection: Check and repair the main circuit and drive Pr6.

What to do if arc can not be ignited on CANAWELD Welding System (TIG)?
- E
  Elizabeth LeonardAug 20, 2025
  If the arc cannot be ignited during TIG welding, consider the following: * Ensure the welding cable is correctly connected to the welder's output. * Check the welding cable for damage and repair or replace it if necessary. * Verify the earth cable connection is stable. * Use an appropriate welding cable length. * Clean any oil or dust from the workpiece. * Inspect the HF igniting board; repair or replace Pr8 if it's not working. * Check the welding gun switch, control cable, and aero socket for malfunctions.

What to do if there is no gas flow in CANAWELD TIG AC DC 201 pulse D Welding System (TIG)?
- K
  Kimberly AndersonAug 23, 2025
  If there is no gas flow during TIG welding, check these: * Ensure the gas cylinder is open and the gas pressure is adequate; open or change the gas cylinder if needed. * Check for obstructions in the valve and remove them. * If the electromagnetic valve is damaged, replace it.

What to do if the welding current displayed isn’t accordant with the actual value on CANAWELD TIG AC DC 201 pulse D Welding System?
- J
  Johnny PierceAug 26, 2025
  If the displayed welding current doesn't match the actual value: * If the minimum value displayed isn’t accordant with the actual value, adjust potentiometer Imin on the power board. * If the maximum value displayed isn’t accordant with the actual value, adjust potentiometer Imax on the power board.

Why does gas always flow in CANAWELD TIG AC DC 201 pulse D Welding System?
- G
  Gregory PerezAug 28, 2025
  If the gas is always flowing, consider these solutions: * Ensure the gas-test on the front panel is off. * Check for obstructions in the valve and remove them. * If the electromagnetic valve is damaged, replace it. * If the adjustment knob of pre-gas time on the front panel is damaged, repair or replace it.
