What to do if there is no welding current in my Fronius TPS 320i Welding System?
If your Fronius Welding System shows no welding current, first, check the grounding connection and terminal for correct polarity. If the grounding is correct, the issue might be a break in the current cable within the welding torch, requiring you to replace the welding torch.
Why is there no protective gas shield in my Fronius TPS 320i Welding System?
If your Fronius Welding System isn't providing a protective gas shield, start by changing the gas cylinder. If the issue persists, the gas pressure regulator may be faulty and require replacement. Also, check the gas hose for proper connection, damage, or kinks, and connect/replace it or straighten out any kinks. If those steps don't solve the problem, the welding torch or gas solenoid valve might be faulty and need to be changed.
How to troubleshoot a Fronius TPS 320i Welding System power source that does not function?
If your Fronius Welding System's power source isn't functioning, begin by checking the mains lead and ensuring the mains plug is securely plugged in. If the problem persists, examine the mains socket and plug for faults, replacing any defective parts. Finally, inspect the mains fuse and change it if it's faulty.
What causes poor weld properties in a Fronius Welding System and how to fix it?
If your Fronius Welding System is producing poor weld properties, verify the welding parameters are correct. Ensure a good grounding connection to the workpiece. Check for an adequate protective gas shield by inspecting the pressure regulator, gas hose, gas solenoid valve, and torch gas connection. Replace the welding torch if it's leaking, and replace the contact tip if it's wrong or worn out. Finally, check the wire electrode and the weldability of the base metal, and use the correct shielding gas for the wire alloy.
What to do if nothing happens when torch trigger is pressed on my Fronius Welding System?
If nothing happens when you press the torch trigger on your Fronius Welding System, first ensure the control plug is securely plugged in. If the issue continues, the welding torch or its control line may be faulty and need replacement. Also, check the interconnecting hosepack for faults or improper connection.
Why is there no welding current in my Fronius Welding System?
If your Fronius Welding System has no welding current, check the duty cycle. If the duty cycle has been exceeded, let the power source cool down. If the thermostatic automatic circuit breaker has tripped, wait for the power source to automatically come back on after the cooling phase. Ensure accessibility to cooling-air ducts. If the fan in the power source is faulty, it should be replaced by After-Sales Service.
How to fix irregular wire feed speed on my Fronius TPS 320i?
If your Fronius Welding System has an irregular wire feed speed, try loosening the brake if the braking force has been set too high. Use a suitable contact tip if the hole in the current one is too narrow. Check the inner liner in the welding torch for kinks or dirt. Use suitable feed rollers for the wire electrode being used, and optimise the contact pressure of the feed rollers.
Why does the welding torch become very hot on my Fronius TPS 320i Welding System?
If the welding torch of your Fronius Welding System becomes very hot, observe the duty cycle and loading limits of the welding torch. If you are using a water-cooled machine, check the coolant fill level, coolant flow, and for coolant contamination.
What to do if my Fronius Welding System has no welding current?
If your Fronius Welding System has no welding current, several factors could be the cause. First, the duty cycle may have been exceeded, so check it. Second, the thermostatic automatic circuit breaker might have tripped; in that case, wait for the power source to automatically restart after the cooling phase. Third, ensure that the cooling-air ducts are accessible, as a limited supply of cooling air can cause this issue. Finally, the fan in the power source could be faulty, requiring replacement by After-Sales Service.
