Regula® EWR – for active gas-flow regulation!

A cost efficient solution for Automatic and Manual ARC-Welding

You earn more of buying Regula EWR, than we ever can earn from selling it.

Patented technology Regula® EWR gas regulator is a world-wide patented product from the Swedish company Regula Systems AB. The regulator adjusts to the welding process by sensing the varia-tions in the current supply and automatically regulates the gas-flow.The gas-flow is therefore maintained at an optimal level and as a result you will achieve uniformed weld seams with a reduced gas-consumption.

Robot ABB, Aristorob 500, ELGA Optimator. Welding of a cuttingdeck

on Husqvarna ”Rider” Lawnmover. Weld seams: 20

Blue curve: Without Regula® EWR. Gas consumption: 17,2 litre/welding-cycle

Red curve: With Regula® EWR. Gas consumption: 9.0 litre/welding-cycle

Savings: 8.2 litre/welding-cycle = 47,7%

The solution Regula® EWRIn EWR for Manuel welding you can use the incoming pressure bet-ween 2-6 bars and the outgoing gas-flow between 3-27 litres.The outgoing and incoming gas-flow will automatically be regulated by your supply of current.To optimize your welding process, simply push the button on the front panel.

Save 41.731€/yearBased on this example with 9 robots working 3 shift; 7 robots working 2 shift; 5 robots working 1 shift, 5 hours per shift, 220 days per year consuming 18 litres of gas every minute – you will save 41.731€ in one year. Actually, it only takes 6 months of production to save gas costs equivalent to the investment costs! Make sure to order your EWR units already today!

Example of savings using EWR

+ Less welding spatter + Lossless production + Less impact on environment

The market for welding robots (arc welding) is large. In 2006 there were an estimated 400 000 welding robots in the world

If we assume a 30% gas saving on all robots that each run on two shifts, the total saving will be 300 billion liters of gas a year

The total yearly gas savings is 920 million EUR

Technology from Regula Systems will offer large environmental

and economic savings
