Why does my Mosa TS 300 KSX weld poorly?
Poor welding performance in your Mosa Welding machine can stem from a defective diode bridge or a problem with the welding current control PCB. Check the open circuit welding voltage. If it's okay, the diode bridge is likely fine. However, if it's at 1/3 or 2/3 of the nominal value, inspect the diodes or SCRs. If the diode bridge is confirmed to be working correctly, consider replacing the PCB.
How to troubleshoot intermittent poor welds on a Mosa Welding machine?
If your Mosa Welding machine intermittently welds poorly, the issue might be due to bad connections to the welding current PCB or a problem with the welding current control PCB itself. Start by ensuring the pins of the green connectors are clean and making good contact, and verify that all shunt connections are tight. If the problem persists, replace the welding current control PCB.
How to fix a Mosa TS 300 KSX with no welding current but auxiliary output is OK?
If your Mosa Welding machine has no welding current but the auxiliary output is working, the issue could be a defective diode bridge or a problem with the welding current control PCB. Here's what you can do: 1. Check the diodes of the bridge. 2. Ensure the remote control switch is in the internal position. 3. Check the diodes and SCRs of the bridge. 4. Check the transformer that supplies power to the welding control PCB. If it's working, replace the PCB.
What to do if my Mosa Welding machine has no welding output and no auxiliary power output?
If your Mosa Welding machine has no welding output and no auxiliary power, possible causes include a short circuit in the wiring, a defective condenser, a defective stator, or a short-circuited diode bridge. First, check the wiring inside the welder for a short circuit between cables or to ground. If the wiring is okay, short circuit the condenser to ensure it's discharged, then disconnect all wires and check with an ohmmeter to see if the condenser is short-circuited. If the condenser is okay, disconnect all leads from the stator (except those to the condenser box) and check the alternator output. If there's no output from either the welding or auxiliary winding, replace the stator. If there is output from all windings, reconnect the diode bridge and check for welding current. If there's ...
