Pressing any of the switches (buttons) will NOT feed the wire. The motor does NOT run.58The wire will not feed and the circuit breaker (CB1) trips when the inch down, inch up or the start buttons...59When the inch up button is press the wire feeds down. When the inch down button is pressed the wire feeds up.59The wire will not feed when the inch down button is pressed. The wire does inch up OK and feeds down...60The wire will not inch down but does inch up properly. The wire does not feed in either direction when the start...61The wire will not inch down but does inch up properly. When the start button is pressed the wire feeds up...61NA-5 units above code 8300 with “cold starting”. The wire feeds up instead of down when the start button is pressed.62NA-5 units above code 8300 with “cold starting”. While pressing the inch down button the wire does not stop when it touches.63The wire will NOT inch up but does inch down and weld properly.63The wire feeds UP when either inch button is pressed.63The wire feeds down when either inch button is pressed.64The speed and voltage controls do not function. All of the mode lights function properly.65All the mode lights function properly. None of the speed controls operate properly.65All the mode lights function properly. None of the voltage controls operate properly.65Only the strike mode functions, when the unit is at idle, regardless of the selector switch position.66Only the strike mode functions while welding. The unit stays in the strike mode and does not progress through...66The strike light is OFF and neither strike control functions. The other mode lights work. The unit will not...66The strike light does not light. The strike controls (voltage and wire feed speed) do function normally.67The strike light comes on but the strike controls (voltage and wire feed speed) do not function normally.67The start light does not light. The start controls (voltage and wire feed speed) may or may not function normally.67The start light is ON but the start controls (voltage and wire feed speed) do not function. The NA-5 is...67When the start button is pressed and the unit is welding, the start mode is skipped.68When welding the start timer does not time out. The unit stays in the start mode.69The crater light does not light. The crater controls (voltage and wire feed speed) may or may not function.69The crater light is ON but the crater controls (voltage and wire feed speed) do not function. The NA-5 is...69At the end of the weld the crater light does NOT light.70At the end of the weld the crater timer does not time out. The unit stays in the crater mode.70No burnback/retract occurs at the end of the weld.70The burnback timer does not time out properly.71The weld light does not light. The weld controls (voltage and wire feed speed) may or may not function.71The weld light is ON but the weld controls (voltage and wire feed speed) do not function. The NA-5 is...71During the welding sequence the weld light does not go ON.72While welding the weld mode is omitted in the welding sequence. The weld timer is set for a longer...72The weld timer does not time out. the unit stays in the weld mode.72The start button does not initiate the power source output or the wire feed. The mode selector switch is in...73The start button initiates the power source output, but the wire does not feed.73The start button initiates the wire feed, but does not activiate the power source output.74The travel function will not operate regardless of the travel switch position.75The travel will not function with the travel switch in the “Hand” travel position. The unit operates properly...75The travel will not function with the travel switch in the “Auto” postion. The travel operates correctly with the...76The travel runs continuously when the travel switch is in the “Auto” position.76After pressing the stop button, the electrode “Hot” light goes OFF, but the electrode wire remains electrically...77After pressing the stop button, the weld light remains on and the wire continues to feed.77The set and actual speed meter readings match within a few IPM, but both are in error.77The set speed and actual speed meter readings do not match within a few IPM. One or both readings may be erratic.78The set speed is adjustable and steady. The actual speed is uncontrollable. The meter displays the actual speed correctly.78The set speed is adjustable and steady. The actual speed reading is incorrect and or erratic.79The set volts and actual volts readings match within a few tenths of a volt while welding. However both...79The actual volts reading does NOT match the set volts reading within a few tenths of a volt. One reading...80The NA-5 repeatedly shutsdown while welding.81The circuit breaker trips when the inch up, inch down, or start buttons are pressed.82The circuit breaker trips and or the fuse (F101) blows when the NA-5 is turned on. (input power applied).82The circuit breaker trips after the wire has been feeding for a period of time. Welding is normal.83The 1/8 amp fuse on the voltage board repeatedly fails.83The arc voltage appears to rise too slowly. The wire stubs or blasts off at the start of the weld sequence.84The voltage seems too high or flares excessively at the start of the weld sequence. Once the arc is established...84The arc is unstable or oscillating.85The flux or gas/water solenoid does not function (open).86The flux or gas/water solenoid continuously remains open.86The arc is unstable or oscillating.87The welding arc is variable or “hunting”.87Poor arc striking with sticking or “blast offs”. The weld bead is ropey and has porosity.88Section G - Electrical Diagrams140Größe: 2,28 MBSeiten: 152Language: EnglishHandbuch öffnen
