  If your Fronius welding machine doesn't function when you press the torch trigger, start by ensuring the control plug is properly connected. If it is, the welding torch or torch control lead might be defective; try exchanging them. Also, check if the welding torch connection socket is expanded and bend the contacts on the torch connecting plug accordingly. Inspect all plug connections between the torch trigger, control lead, and power source, and clean out any dirt between the trigger button and the button housing. As a last resort, the PCB in the welding torch might be defective, and you will need to replace it.

  If you're getting high-frequency arc-over on the handle shell of your Fronius Welding Accessories, it's likely due to a leaking hosepack. In this case, you should replace the hosepack. Alternatively, the shielding gas hose connection to the torch body might be leaking, requiring you to cut back the hose and reseal it.

  If you have no shielding gas with your Fronius Welding Accessories, first, check if the gas cylinder is empty and change it if needed. If the cylinder isn't the problem, the gas pressure regulator might be faulty, requiring replacement. Also, inspect the gas hose to ensure it is properly mounted, not damaged, and not kinked; mount, straighten, or exchange it as necessary. The welding torch itself could be faulty, so try exchanging it. Finally, the gas solenoid valve might be faulty, and you should exchange it.

Why is the Fronius TTW 4000 torch becoming very hot?
- A
  Arthur CohenSep 4, 2025
  If your Fronius welding torch becomes very hot, it might be because the torch's design dimensions aren't sufficient for the task. Make sure to respect the duty cycle and loading limits. Also, particularly on water-cooled machines, insufficient water through-flow could be the issue. Check the coolant level, through-flow rate, coolant cleanliness, and hosepack arrangement. If the coolant pump is blocked, use a screwdriver on the bushing to turn the shaft of the coolant pump.
