No weld out-put - no 115 VAC at the receptacle. (220 VAC receptacle on European models only).44No welding output. The 115 VAC is present at the receptacle. (220 VAC receptacle on European models only).45No output from the machine in either Stick or TIG modes. The thermal light is on.46The machine does not respond (no gas flow, no high frequency and no open circuit voltage) when the arc...46The machine does not have welding output in the Stick mode. The machine operates correctly in the TIG mode.47The machine welds at a very low output regardless of the current control setting.47The machine welds at a very high output regardless of the current control setting.48Accessories plugged into the 115 volt receptacle do not work. (220 VAC receptacle on European models only).48The machine makes a very loud buzzing noise in DC Stick or in DC TIG modes. There is no current...49The machine output is intermittently lost. Gas flow and high frequency are also interrupted.50No gas or water flow (with optional water solenoid) when the arc start switch or Amptrol is activated in the...50No high frequency. The machine is in the TIG mode and has normal output.51The high frequency “spark” is present but weak.52The high frequency “spark” is present at the tungsten electrode, but the operator is unable to establish...53When AC TIG welding, the arc is erratic and there is a loss of “cleaning” of the work piece.53The stick electrode “blasts-off” when touched to the work piece.54Variable or sluggish welding arc when welding in the Stick mode.54The control panel displays do not function correctly.55The voltmeter always reads “000” but the welding output is normal.55The ammeter display reads “000.” The machine has output but no control.56One of the display meters is blank.56The AC wave balance control does not function properly.57Section G - Electrical Diagrams101文件大小: 1.8 MB页数: 111Language: English打开用户手册
