故障检修WSE-250、WSE-315
故 障 排 除
风机不转,数字表头无显示,无焊接输出 1． 确认空气开关完好或闭合.
2． 确认输出电缆所接电网有电.
3． 电源板上热敏电阻（四只）损坏（这种情况一般是DC24V继电器未合或触点接触不良所致）.
4． 电源板（底板）出现故障,无DC537V电压输出.
5． 控制板上的辅助电源部分出现故障
风机转,异常指示灯不亮,无高频放电“沙沙”声,“擦弧焊”也不能起弧 1． 检查机内各种接插线接触不良.
2． 控制电路问题,查找原因或与经销商联系.
3． 焊枪上的控制线断.
异常指示灯不亮,有高频放电“沙沙”声,无焊接输出 1． 焊枪电缆断.
2． 地线断或未连接到焊接工件上.
3． 正极输出端子或焊枪气电输出端子与机内的连接处松脱.

Trouble shooting for model WSE-250, WSE-315
Problems
Ventilation fan not running, no indication on the digital meter, no welding output current.
Causes and Solutions
1.Ensure the air switch is intact or off.
2.Ensure the output cable is connected to a live power source.
3.Thermistors on the power panel (4 units) are damaged [Normally, this is due to the 24V relay broke contact or poor contact at the contact points.]
4.Failure of the power panel (bottom), no DC537 voltage output.
5.Partial failure of the auxiliary power source on the control panel.
Problems
Ventilation fan running, abnormal indicator light is off, no high frequency discharge with “sha sha” noise, arc striking not effective.
Causes and Solutions
1.Check for any poor contact of the various wiring connections inside the machine.
2.Circuit control problems. Check for causes or contact the dealer.
3.Control cable of welding torch severed.
Problems
Abnormal indicator light is off, high frequency discharge with “sha sha” noise,
no welding output current.
Causes and solutions
1.Welding torch cable severed.
2.Grounding cable severed or not connected to welded object.
3.The output terminal of the positive pole or the output terminal of electro-gas of the welding torch that connects with the joint inside the machine loosened or disconnected.
