No output - No fan42The fan runs normally. No output from the machine in either Stick or TIG modes.42Fan runs - No output from machine in either Stick or TIG modes and the yellow light on the control panel is on.43The machine does not respond (no gas flow, no high frequency and no open circuit voltage) when the arc start switch or Amptrol is activated - fan is working normally.43Machine regularly over heats - thermostat opens. Yellow light on front panel glows. The fan runs but the machine has no output.44The machine does not have output in the Stick mode. The machine operates correctly in the TIG mode.44Machine welds at a very low output regardless of the current control setting.45The machine welds at a very high output regardless of the current control setting.45Machine output is intermittently lost. Gas flow and high frequency are also interrupted.46The arc "flutters" when TIG welding.47The arc "pulsates" when AC TIG welding.47Black areas along weld bead.48Weak high frequency - machine has normal welding.48High frequency "spark" is present at tungsten electrode, but operator is unable to establish a welding arc. Machine has normal open circuit voltage. Refer to Technical Specifications in the Installation Chapter.49No high frequency. Machine is in the TIG mode and has normal output.50No gas flow when Amptrol is activated in the TIG mode. Machine has normal output - fan runs. A "click" can be heard indicating that the gas solenoid valve is operating.50When AC TIG welding, the arc is erratic and there is a loss of "cleaning" of the work piece.51The end of the tungsten electrode melts away.51Stick electrode "Blasts Off" when arc is struck.52The stick electrode "sticks" in the puddle.52Variable or sluggish welding arc when welding in the Stick mode.52Section G - Electrical Diagrams97Tamanho: 2 MBPáginas: 104Language: EnglishAbrir o manual
