UVV - Safety inspection is a must!

This inspection should be performed at least once a year. If requested, we use our mobile calibration system to perform technical safety testing standards conform to the latest (German) BGV A3 accident prevention regulations and the DIN EN 60974-4 standard, which specifi es the specific requirements to be met by welding machines. Without the cumbersome need to switch connections between welding machine and calibration system. This helps save valuable time and money and offers the extra benefi t of detecting possible major subsequent damages well in advance.
