What causes arc or short circuit between contact tip and gas nozzle in LORCH M 2070 CuSi?
An arc or short circuit between the contact tip and gas nozzle in your LORCH Welding System can be caused by spatter build-up inside the gas nozzle. Remove it with special pliers.
What causes higher wire wear out at wire-feeding unit of LORCH Welding System?
Higher wire wear out at the wire-feeding unit of your LORCH Welding System can occur if the wire rolls do not fit the wire diameter. Install the correct wire rolls. It can also be caused by incorrect contact pressure at wire feeding; adjust as described in the manual.
What to do if there is not sufficient shielded gas in my LORCH Welding System?
If there is not sufficient shielded gas in your LORCH Welding System, it could be due to: * Wrong adjusted quantity of shielded gas: Adjust it correctly as described in the manual. * Dirty pressure reducer: Check the valve. * Torch, gas hose blocked or not airtight: Check and replace if necessary. * Shielded gas being blown away by draught: Avoid draught.
What to do if mains control lamp 40 does not light on LORCH M 2070 CuSi Welding System?
If the mains control lamp 40 does not light on your LORCH Welding System, it means that a phase is missing in the mains. Check the machine at another socket and check mains and fuses.
What to do if the fan of my LORCH M 2070 CuSi is not working?
If the fan of your LORCH Welding System is not functioning, it indicates a missing phase in the mains. Check the machine at another socket and check the mains and fuses.
