Why is there no weld output, wire doesn't feed, but the fan doesn't run on my Hobart Welding System?
Here are a few things to check: * Make sure the power cord is securely plugged into the receptacle. * Check and replace the building line fuse or reset the circuit breaker if it's open. * Ensure the power switch is in the On position. * Reset the welding power source circuit breaker if it's open.
Why is there no weld output, but the wire feeds on my Hobart Welding System?
If you're getting wire feed but no weld output, try these solutions: * Ensure the work clamp has good metal-to-metal contact. * Replace the contact tip. * Verify proper polarity connections. * Tighten the thumbscrew securing the gun end to the feed head adapter.
What to do if electrode wire feeding stops during welding with my Hobart Welding System?
If the electrode wire stops feeding during welding, consider these steps: * Straighten the gun cable or replace any damaged parts. * Adjust the drive roll pressure. * Change to the correct drive roll groove. * Readjust the hub tension. * Replace the contact tip if it's blocked. * Clean or replace the wire inlet guide or liner if they're dirty or plugged. * Replace the drive roll or pressure bearing if they're worn or slipping. * Secure or repair the gun trigger leads. * Check and clear any restrictions at the drive assembly and liner. * Release the gun trigger and allow the gun and motor protection circuitry to reset. * Ensure the gun is secured to the feed head by tightening the thumbscrew. * Have a Factory Authorized Service Agent check the drive motor.
Why is there no weld output, wire doesn't feed, but the fan motor continues to run on my Hobart Welding System?
If you have no weld output and the wire isn't feeding, but the fan motor is still running, here's what you can check: * If the thermostat TP1 is open due to overheating, let the fan run with the gun trigger switch off to cool the unit down until the thermostat closes. * Check the Voltage range switch position and ensure it 'clicks' into the desired range setting. * Ensure the Voltage range switch isn't set to the 'PURGE' position; set it to position 1, 2, 3, or 4. * Make sure the gun trigger leads are secure.
How to fix low weld output on my Hobart Welding System?
If you're experiencing low weld output, try the following: * Connect the unit to the correct input voltage or check for low line voltage. * Place the voltage switch in the appropriate position.
