What to do if Hobart Welding System has no weld output, wire does not feed, but the fan motor continues to run?
If your Hobart Welding System exhibits no weld output and the wire doesn't feed, but the fan motor is still running, it could be due to overheating. Allow the fan to run with the gun trigger switch off; the thermostat will close once the unit has cooled down. Also, make sure the gun trigger leads are securely connected.
Why does electrode wire feeding stop during welding with my Hobart Handler 135 Welding System?
If the electrode wire feeding stops during welding with your Hobart Welding System, try the following: * Straighten the gun cable and 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 it's dirty or plugged. * Replace the drive roll or pressure bearing if they're worn or slipping. * Secure the gun trigger leads or repair them. * 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. * Have a Factory Authorized Service Agent check the drive motor.
How to fix Hobart Handler 135 Welding System with no weld output, wire feed, or fan?
To fix a Hobart Welding System with no weld output, wire feed, or fan, start by ensuring the power cord is securely plugged into the receptacle. Next, replace the building line fuse or reset the circuit breaker if it's open. Also, make sure the power switch is in the On position and reset the welding power source circuit breaker if it's open.
What to do if Hobart Handler 135 has no weld output and wire feeds?
If your Hobart Welding System has no weld output but the wire feeds, ensure the work clamp is connected to establish good metal-to-metal contact. You may also need to replace the contact tip. Also, check for proper polarity connections and make sure the thumbscrew securing the gun end to the feed head adapter is tight.
