What to do if CB1 opens and the Hobart Welding System shuts down?
If CB1 opens and the unit shuts down, you can try the following: Reset the supplementary protector. Also, release the gun trigger and wait until the protection circuit resets, allowing the drive motor to feed wire again.
Why Hobart Handler 190 has no weld output, wire does not feed, and fan does not run?
If your Hobart Welding System exhibits no weld output, the wire doesn't feed, and the fan isn't running, consider the following: ensure the power cord plug PLG1 is securely in the receptacle, replace any open building line fuses or reset tripped circuit breakers, verify the power switch S1 is in the On position, and reset the power source supplementary protector if it's open.
What to do if Hobart Handler 190 has low weld output?
If your Hobart Welding System is showing low weld output, make sure that the unit is connected to the correct input voltage, or check if the line voltage is low. Also, set the Voltage switch S2 to the desired position. If you're using an extension cord, ensure it's the correct size for the input voltage and amperage.
Why Hobart Handler 190 Welding System wire does not feed; wire is not energized; wire feeds unevenly?
If the wire on your Hobart Welding System isn't feeding, isn't energized, or feeds unevenly, check the contact tip and for kinks in the gun cable and liner. Also, verify the gun trigger plug connection at the welding power source/wire feeder. Some other things to check: * Replace the gun trigger switch if necessary. * Straighten the gun cable or replace any damaged parts. * Readjust the drive roll pressure and wire spool hub tension. * Change to the proper groove.
Why Hobart Welding System has low or erratic wire speed?
If you're experiencing low or erratic wire speed with your Hobart Welding System, try these solutions: readjust the weld parameter settings and drive roll pressure. Also, change to the correct size drive roll, clean or replace the wire inlet guide or liner if it's dirty or plugged, readjust the wire reel hub tension, and check the voltage and connections of the wire drive motor, replacing the motor if needed.
What to do if Hobart Handler 190 weld output is present, but wire does not feed?
If your Hobart Welding System has weld output but the wire isn't feeding, switch the MIG Gun/Spool Gun selector switch to operate the desired gun. The MIG Gun position is for the integrated wire feed motor operation, and the Spool Gun position is for the spool gun wire feed motor operation.
Why Hobart Handler 190 Welding System has no weld output but wire feeds?
If the Hobart Welding System has no weld output but the wire is feeding, make sure the work clamp has good metal-to-metal contact. You may also need to replace the gun contact tip, and ensure the thumbscrew securing the gun end to the feedhead adapter is tightened.
Why Hobart Welding System has no weld output; wire does not feed; fan runs?
If your Hobart Welding System has no weld output and the wire isn't feeding, but the fan is running, verify the Voltage switch S2 position and rotate the knob until it clicks into place at the desired range setting. Also, ensure the gun trigger plug is securely connected to receptacle RC3 and that the Spool Gun/MIG Gun switch S3 is in the correct mode. Check the continuity of the gun trigger leads and the Voltage switch S2, repairing or replacing as necessary. Finally, inspect the diodes in the main rectifier SR1 and the main transformer T1 for any signs of failure, and check the control board PC1 connections and voltages.
Why Hobart Handler 190 has weld porosity?
To address weld porosity in your Hobart Welding System, remove any weld spatter buildup in the nozzle. Check the O-rings on the gun connector and replace them if they're damaged. Also, ensure the inner head tube is tight in the cable connector, and the gun connector is fully inserted into the drive assembly. Finally, verify the shielding gas flow/supply.
Why Hobart Handler 190 Welding System shielding gas flows continuously?
If the shielding gas flows continuously on your Hobart Welding System, check the gas valve for debris and remove any you find. If the problem persists, replace contactor CR3.
