Ensure that the shielding gas cylinder is not empty and the flow meter is correctly adjusted to 15 liters per minute. * There may be gas leaks. Check for gas leaks between the regulator/cylinder connection and in the gas hose to the Power Source. * The hose from the solenoid valve to the torch adapter may be fractured or disconnected. Ensure the hose is intact and connected to the torch adapter. * The weld area may not be shielded from wind. Shield the weld area from the wind or increase the gas flow. * The workpiece may be contaminated. Clean contaminants off the workpiece. * The MIG torch nozzle may be too far from the workpiece. Keep the distance between the MIG torch noz...
