What to do if the Hobart Welding System has no weld output and the high temperature light is on?
If your Hobart Welding System shows no weld output and the high temperature light is on, it could be due to the unit overheating and triggering a thermal shutdown. Let the unit cool down while the fan is running. Alternatively, try reducing the duty cycle or amperage. Also, make sure there is no blockage of airflow to the unit.
How to fix a Hobart Welding System with no weld output and the ready light off?
If your Hobart Welding System has no weld output and the ready light is off, first ensure that the line disconnect switch is in the On position. Then, check the line fuses and replace them if needed, or reset the circuit breaker. Also, verify that the power cord is properly plugged into a receptacle that is receiving power.
What does it mean when the blue light flashes on my Hobart Welding System?
If your Hobart Welding System is not providing weld output, and the blue light flashes continuously while the yellow LED is off, it could be due to the line voltage being too high or too low. Ensure the line voltage is within ±10%. You might also need to reset the unit by cycling the power off and back on.
What to do if Hobart Welding System has no weld output, but ready light is on?
If your Hobart Welding System shows no weld output but the ready light is on, check that the weld cables are securely connected into their receptacles. Also, make sure the work clamp has a good connection to the workpiece.
Why is the fan not working on my Hobart Welding System?
If your Hobart Welding System fan is not operating, first check for any obstructions that may be preventing the fan from moving freely. It's also possible that the unit hasn't warmed up enough to require fan cooling.
How to troubleshoot an erratic welding arc on a Hobart Welding System?
If your Hobart Welding System is producing an erratic or improper welding arc, use the correct size and type of weld cable. Ensure that weld connections are clean and tight. You may also want to check and reverse the polarity, and ensure that connections to the workpiece are solid.
Why does my Hobart Welding System have stick welding problems?
If you're experiencing stick welding problems such as hard starts, poor welding characteristics, or unusual spattering with your Hobart Welding System, be sure to use the correct type and size of electrode. Check and reverse the electrode polarity, and ensure that all connections are secure. Also, make sure a remote control is not connected.
How to fix TIG welding problems on a Hobart Welding System?
If your Hobart Welding System is experiencing TIG welding problems, such as a wandering arc, hard starts, poor welding characteristics, or spattering, use the correct type and size of tungsten. Ensure the tungsten is properly prepared, and check and reverse the electrode polarity.
Why is the tungsten electrode oxidizing on my Hobart Welding System?
If the tungsten electrode is oxidizing and not remaining bright after welding with your Hobart Welding System, shield the weld zone from drafts. Also, check that you are using the correct type of shielding gas, and inspect and tighten all gas fittings. You may also need to check and change the electrode polarity.
