What to do if there are gas leaks in my Thermal Arc FABRICATOR 181i?
If you suspect gas leaks, check the connections between the regulator and the cylinder, and also inspect the gas hose leading to the power source.
What to do if there is limited or no shielding gas flows out of the Thermal Arc FABRICATOR 181i's MIG Gun nozzle?
Check that the MIG Gun connection is fully engaged into the MIG Gun Adapter. The o-rings in the MIG Gun connection must seal the shielding gas within the MIG Gun Adapter so the shielding gas flows into the MIG Gun and out thru the MIG Gun nozzle.
What to do if internal gas hose is damaged in Thermal Arc Welding System?
Check the hose from the solenoid valve to the MIG Gun adapter. Make sure it isn't fractured and is properly connected to the MIG Gun adapter.
How to check shielding gas for Thermal Arc Welding System?
Ensure that the shielding gas cylinder is not empty and the flow meter is correctly adjusted to 15 litres per minute.
How to find gas leaks in Thermal Arc FABRICATOR 181i Welding System?
Check for gas leaks between the regulator/cylinder connection and in the gas hose to the Power Source.
How to maintain the MIG torch of Thermal Arc Welding System?
To maintain the MIG torch in good working order: * Ensure that the gas holes are not blocked and gas is exiting out of the torch nozzle. * Do not restrict gas flow by allowing spatter to build up inside the torch nozzle. * Check that the MIG torch O-rings are not damaged.
How to maintain the MIG Gun in good working order for Thermal Arc FABRICATOR 181i?
To keep your MIG Gun in good shape: * Make sure the gas holes are not blocked so gas can exit the MIG Gun nozzle. * Prevent spatter buildup inside the MIG Gun nozzle to avoid restricting gas flow. * Check the MIG Gun O-rings for any damage.
