Why does the wire keep feeding after releasing the trigger on my Boss Inverter?
If the wire continues to feed even after you release the gun trigger switch on your Boss Inverter, it's likely that the mode selector switch is set to 4T (latch operation). To fix this, simply set the mode selector switch to 2T (normal operation).
What to do if the warning light is on for Boss Mig 250?
If your Boss Inverter's warning indicator light is on, it indicates an overload. To resolve this, reduce the current or wait a moment.
What to do if nothing happens when I press the gun trigger on my Boss Mig 250?
If your Boss Inverter has input power and the indicator light is on, but nothing happens when you depress the gun trigger switch, it's likely that the gun trigger switch leads are disconnected. You should reconnect them.
Why won't a welding arc establish, even though the power light is on, on my Boss Inverter?
If the welding arc cannot be established and the AC power indicator light is on for your Boss Inverter, it could be due to an unstable input voltage or diode PCB damage. Try connecting a stabilizer or resetting the power switch. If that doesn't work, the diode PCB may need repair or replacement.
What to do if wire feeds but no arc on my Boss Mig 250 Inverter?
If the wire feeds when you depress the gun trigger switch but the arc cannot be established on your Boss Inverter, it is likely due to a poor or no work lead connection. Clean the work clamp area and ensure good electrical contact.
Why does the current decrease while welding with my Boss Mig 250?
If the current decreases during the weld process with your Boss Inverter, the cable connected to the work piece may be faulty. Ensure the cable is correctly and positively connected to the work piece.
What to do if the indicator light is off and no arc on my Boss Inverter?
If the input power supply is on, the indicator light is not lit, and a welding arc cannot be established on your Boss Inverter, it could be due to a blown primary fuse or a broken connection in the primary circuit. Replace the primary fuse. For the broken connection, have an accredited BOSS service agent check the primary circuit.
Why is there no wire feed but gas flows on my Boss Mig 250 Inverter?
If the input power supply is ON, there is no wire feed, but gas flows from the MIG gun when the gun trigger switch is depressed on your Boss Inverter, it could be due to: A. Electrode wire stuck in conduit liner or contact up (burn-back jam). B. Faulty control PCB. Check for clogged/ kinked MIG gun conduit or worn contact tip, replace faulty components. Have an accredited BOSS service agent investigate the faulty PCB.
Why does my Boss Inverter have no arc weld output?
If the arc weld has no output on your Boss Inverter, it could be due to a bad connection in either the diode PCB or the relay PCB. Repair or replace the affected component.
How to fix a Boss Mig 250 Inverter when the power light is off and there's no welding arc?
If your Boss Inverter's AC power indicator light is not lit and you cannot establish a welding arc, it could be due to no power input, damage to the main power switches, or indicator damage. Check the input power and replace the main power switch if necessary. Also, replace the indicator light if it is damaged.
