Abstract

The pressure gauges indicate pressure drop in the high pressure side in front of the redn valve and built up pressure behind it, the high pressure indicator being fitted with a device for setting the lowest value so that a constant gas supply is assured, whilst the low pressure gauge has a device for setting the highest pressure of that part of the system from which the supply to the welding head branches. The system ensures that welding is carried out only when the protective gas is supplied correctly switching the gas and current supply off when the set limits are passed.
