[MW:1376] Fwd: [MW:1374] Re: Calibration, Validation of welding machines as per BS 7570 standard.

Dear All,

 

Plz find review BS EN 17662-2005. Hope it helps !!! I tried to attach the std. but it exceeds the attachment limit.

 

Normally, as a standard practice, we go for a FUNCTION CHECK for the welding machines i.e., using a calibrated Digital Clampmeter to check the output of the Welding machine after setting the required current/voltage paramaters, making sure before checking that the input supply to the welding machine is as per requirement (recording fluctuations in power supply, if any).

 

Regards,

Puru.
