What to do if the Hanshen NBC-250D ampere meter displays E01 when welding?
If your Hanshen Welding System displays 'E01' on the ampere meter during welding, it indicates a prolonged overload. To resolve this, adhere to the welding machine's duty cycle guidelines during operation.
Why won’t the heating pressure reducing flow meter heat up on my Hanshen NBC-250D Welding System?
If the heating pressure reducing flow meter of your Hanshen Welding System won’t heat up, the possible causes are a broken meter (in which case you should replace it), a short circuit (you should fix the heating cable), a broken fuse (you should change the 8A fuse), or no output from the welder (you should check if there is output from welder).
Why can't I adjust the welding current on my Hanshen NBC-250D?
If you cannot adjust the welding current on your Hanshen Welding System, the issue might be with a broken wire feeder control cable or damaged control PCB (you may need to change the wire feeder control cable or PCB), a broken connection wire of the current divider (you may need to reconnect the lines), or a broken control panel of the welder (you may need to change the control panel).
Why does the air switch shut off when I turn on the Hanshen NBC-250D Welding System?
If the power switch trips immediately after turning on your Hanshen Welding System, it could be due to a broken air switch (you should change the air switch), a broken IGBT (you should change the IGBT), a broken 3-phase commutate bridge (you should change the 3-phase commutate bridge), or a broken controlling panel (you should change the controlling panel).
What to do if wire feeding is normal, but there is no gas flow when pressing the torch switch on my Hanshen NBC-250D?
If pressing the torch switch on your Hanshen Welding System results in normal wire feeding but no gas flow, this could be due to a broken control motherboard of the welder (you should change the control motherboard) or a broken electromagnetic valve (you should change the electromagnetic valve).
How to fix the indicator light if it's not on after switching on the Hanshen NBC-250D Welding System?
If the indicator light on your Hanshen Welding System is not on after switching on the power, it could be due to damage to the air switch on the back panel (you should change the air switch) or a broken fuse (you should change the fuse).
What to do if the wire-feeder doesn't work and there is no open-circuit voltage when pressing the torch switch on my Hanshen Welding System?
If pressing the torch switch on your Hanshen Welding System results in the wire-feeder not working and there's no open-circuit voltage, the torch switch might be broken (you should change the torch) or the control cable of the wire-feeder might be broken (you should fix the control cable of wire-feeder).
Why is there an unstable arc and big splash when using my Hanshen NBC-250D Welding System?
If you're experiencing an unstable arc and big splash with your Hanshen Welding System, it could be due to an incorrect procedure (you should correct the procedure) or a badly worn nozzle (you should change the nozzle).
Ensure correct voltage, comply with laws, wear safety gear, maintain ventilation, and avoid opening the welder's shell.
Keep welder away from inflammables, sparks, and combustion gas sources. Secure installation if needed.
Disconnect power before gas connection, avoid wet gloves, use correct cables, and ensure proper earthing.
Steps include powering on, selecting wire/nozzle, manual wire feeding, and performing a gas test.
Procedure for spot/short seam welds: set end arc OFF, adjust current/voltage, and use torch switch.
Procedure for long welds: set end arc ON, adjust current/voltage, use torch switch for arc start/stop and crater filling.
Ensure secure connections, avoid short circuits, maintain ventilation, and perform regular internal part checks and cleaning.
Guide to diagnosing and resolving common problems like indicator lights, air switch tripping, and unstable arc.
