To Next PageTo Next PageWhy is inert gas missing from my LORCH Welding System?
If inert gas is missing from your LORCH Welding System, possible causes include: * An empty gas cylinder. Replace it. * A faulty torch. Check and replace if necessary. * A dirty or faulty pressure reducer. Check and replace if necessary. * A faulty gas cylinder valve. Replace the gas cylinder.
Why is the welding power reduced on my LORCH M-Pro BasicPlus Welding System?
If you notice reduced welding power in your LORCH Welding System, consider the following: * A missing phase. Try a different power socket and check the supply cable and mains fuses. * Insufficient ground contact at the workpiece. Ensure a good, clear ground connection. * The ground cable is not correctly inserted. Lock the ground connector by turning it clockwise. * A faulty torch. Repair or replace the torch.
What to do if the inert gas feed is insufficient on my LORCH M-Pro BasicPlus Welding System?
If the inert gas feed is insufficient in your LORCH Welding System, consider these possible causes: * The inert gas quantity is set incorrectly at the pressure reducer. Adjust the setting as described in the operating instructions. * A dirty pressure reducer. Check the pressure reducing nozzle. * A blocked or leaking torch or gas hose. Check these components and replace if necessary. * Draughts blowing the inert gas away. Eliminate the draughts.
Why does my LORCH Welding System keep switching off?
If your LORCH Welding System switches off unexpectedly, it could be due to: * Exceeding the duty cycle. Allow the equipment to cool down at no-load. * Insufficient cooling of components. Check the air inlet and outlet on the equipment.
What to do if inert gas is missing from my LORCH Welding System?
If inert gas is missing from your LORCH Welding System, consider the following: * The gas cylinder is empty. Replace it. * The torch is faulty. Check and replace if necessary. * The pressure reducer is dirty or faulty. Check and replace if necessary. * The gas cylinder valve is faulty. Replace the gas cylinder.
How to fix an unstable arc on my LORCH Welding System?
If you're experiencing an unstable arc with your LORCH Welding System, it could be because the contact tip doesn't match the wire diameter, or the contact tip is worn. Check the contact tip and replace it if necessary.
Why does the wire feed unit have increased wire abrasion on my LORCH Welding System?
If you're experiencing increased wire abrasion with your LORCH Welding System's wire feed unit, it could be because the wire feed rollers do not match the wire diameter. Fit the correct feed rollers. Another cause could be incorrect contact pressure on the wire feed unit. Set it as described in the operating instructions.
Why does the torch switch have no function when actuated on my LORCH Welding System?
If the torch switch on your LORCH Welding System has no function when actuated, it could be due to: * The union nut from the torch hose pack to the central socket not being correctly tightened. Tighten the union nut. * An open circuit in the control cable in the torch hose pack. Check and replace if necessary. * Thermal protection being triggered. Allow the equipment to cool down at no-load.
Why is the control panel completely dark on my LORCH M-Pro BasicPlus Welding System?
If the control panel of your LORCH Welding System is completely dark, a phase might be missing. Check the equipment at a different power socket, and inspect the supply cable and mains fuse.
What causes wire to stick or burn onto the contact tip of my LORCH M-Pro BasicPlus Welding System?
If the wire is sticking or burnt onto the contact tip of your LORCH Welding System, it could be: * The wire electrode is jammed on the reel. Check and replace if necessary. * There is a burr at the start of the wire. Trim the end of the wire.
