  If the ON/OFF switch is activated on your Thermal Dynamics Cutter but the A/C Indicator remains unlit, follow these steps: First, ensure the primary power disconnect switch is in the ON position. Then, have a qualified technician inspect the primary fuses or breakers and verify the unit is connected to a functioning primary power receptacle. If necessary, replace the fuse. Should the fuse blow again, the unit should be returned to an authorized service center for repair or replacement.

What to do if FAULT and 80 PSI indicators are flashing and gas flow is cycling on and off on Thermal Dynamics A120?

  If the FAULT and 80 PSI indicators are flashing and the gas flow is cycling on and off on your Thermal Dynamics Cutter, try the following: First, hand-tighten the shield cup, but avoid overtightening. If that doesn't resolve the issue, turn off the power supply, remove the shield cup, and install any missing parts. Next, turn off the power supply again, bleed down the system pressure, and remove the shield cup, tip, and start cartridge to check the start cartridge's lower end fitting for free movement; replace it if it doesn't move freely. Consider replacing the torch and leads.
