Why is my LORCH Welding System machine switching off?
The LORCH Welding System machine might be switching off due to the duty cycle being overloaded, which is indicated by control lamp 39. Allow the machine to cool down. Another cause could be insufficient cooling of machine parts, so check the air inlet and outlet.
What to do if there is less welding performance in my LORCH M 2040 Welding System?
If your LORCH Welding System exhibits less welding performance, it could be due to several reasons: * A missing phase: Check the machine at another socket and inspect the mains and fuses. * Poor ground connection: Ensure the best possible contact between the ground clamp and the workpiece. * Ground cable not properly plugged in: Fasten the ground cable by turning the plug to the right. * Defective torch: Repair or replace the torch. * Defective main rectifier: Check and replace the main rectifier, if required.
What to do if my LORCH M 2040 has irregular or no wire feeding?
If your LORCH Welding System is experiencing irregular or no wire feeding, consider the following: 1. Incorrect contact pressure at the wire-feed rolls: Adjust it as described in the manual. 2. Torch defect: Check and replace if necessary. 3. Missing or dirty brass pipe in the central connection: Install or clean the brass pipe. 4. Poor quality of welding wire: Check and replace if necessary. 5. Rust formation on the welding wire: Check and replace if necessary. 6. Dirty torch liner: Disconnect the torch, unscrew the contact tip, and clean the liner with compressed air. 7. Dejected torch liner: Check and replace if necessary. 8. Motor brake adjusted too strongly: Adjust as described in the manual. 9. Defective main rectifier: Check and replace if required.
Why is there no shielded gas coming from my LORCH Welding System?
If there is no shielded gas in your LORCH Welding System, the possible causes are: * The gas cylinder is empty: Replace it. * Defective torch: Check and replace it. * Pressure reducer is dirty or defective: Check and replace it. * Valve of gas cylinder defective: Replace the gas cylinder.
What to do if my LORCH Welding System's torch button doesn't work?
If there is no function when the torch button is pressed on your LORCH Welding System, the issue might be: * The nut of the torch hose is not tight: Tighten it. * No connection of the control cable in the torch hose: Check and change if necessary. * Overload of the machine and thermal protection is active (control lamp 39 indicates overload): Allow the machine to cool down at no load.
Why is my LORCH M 2040 Welding System's shielding gas not switching off?
If the shielding gas in your LORCH Welding System is not switching off, it could be because the valve of the gas cylinder is dirty or does not close. Remove the torch and pressure reducer and clean it with compressed air.
Why is the plug of ground cable hot in my LORCH M 2040?
If the plug of the ground cable is hot on your LORCH Welding System, check that the plug was tightened by turning it to the right.
What causes an unstable arc in my LORCH M 2040 Welding System?
An unstable arc in your LORCH Welding System can be caused by a contact tip with the wrong diameter or a worn-out contact tip. Change the contact tip.
How to fix irregular wire feeding in LORCH M 2040 Welding System?
Irregular wire feeding or wire welds to the contact tip in your LORCH Welding System can occur if the wire electrode is tight at the spool. Check and change it if necessary. It can also happen if there is a burr at the wire beginning, so cut the wire beginning again.
Why is my LORCH M 2040's torch too hot?
If the torch of your LORCH Welding System is too hot, check if the contact tip is tight.
