Portable Welder

Product Detail

Product description:

1,Dual voltage conversion function: identify high or low voltage, and automatic conversion mode;

2,High and low voltage lock circuit: accurately identify the net pressure level, and ensure the normal operation of the voltage conversion circuit under the fluctuation of the network voltage;

3,Anti electric shock circuit: with VRD shockproof switch, when the welding is stopped, the welding machine no-load voltage is lower than 20V, no electric shock danger, and effectively guarantee the welder's personal safety;

4,Panel function: 220V/380V net voltage indicator, hot arc striking current, thrust current, welding current regulation;

5,Complete protection system: overcurrent, overheating automatic protection, ensure safety, durable and reliable.

Portable Welder Maintenance Methods




When the fan is turned and welded, the output current is unstable or not controlled by a potentiometer, and the current is small when the current is large


 

1) current potentiometer quality problems, should be replaced;

 

2) all kinds of connection bad contact, especially connector, etc., need to check
