Why Hobart Handler 190 has improper or no shielding gas flow?
If your Hobart Welding System has improper or no shielding gas flow, you can try to clean or replace the gas hose. Also, check the shielding gas valve GS1 for proper coil voltage and connections, and check the coil's continuity, replacing GS1 if needed. Finally, clear any blockage in the gun.
