OF COURSE … , that is a fundamental advantage of  WGC1 , he  can work like  a flowmeter and liters totalizer only , without regulation, so can measure the gas that we usually spend for each piece until now ,  and  before   , working as a regulator (adjusting the flow to the indispensable by analysis of the welding), remeasure the gas used by piece, is very simple and fast. Without complicated calculations.

WITH TEN OR TWENTY WELDED PARTS we can know exactly how much liters we spend  per piece , with or without VIGILAWELD  , and calculate just how much we are going to save REALLY ….
