Two-stage regulator equipped with an economizer (gas saver)

In the case of tack welds or short welds, with welding times ranging from a few to several seconds, the cost of shielding gases can exceed the cost of filler metals.

ON THE SHOP FLOOR

Implementing two-stage regulators with economizers reduces total welding costs by decreasing gas consumption and stabilizing weld quality.

IN THE BOARDROOM

It delivers a rapid return on investment (ROI) with a relatively low, one-time capital expenditure, reducing shielding gas costs by several dozen percent.

APPLICATION CONTEXT

Savings in total welding cost.

Replacing a standard regulator with a two-stage regulator equipped with an economizer (gas saver) can be one of the fastest-returning technological investments in a facility.

Traditional regulators generate losses primarily due to the so-called initial gas surge. When the welder stops working, the pressure in the gas hose between the regulator and the welding machine rises on the principle of connected vessels, and high pressure unnecessarily accumulates. With every subsequent arc strike, this trapped excess gas is violently and pointlessly expelled through the torch into the air.

A two-stage system with an economizer solves this in two ways:

  • Eliminates pressure spikes in the gas hoses between the regulator and the welding machine: during downtimes, it maintains the line pressure at a low level, ensuring that the arc strike is smooth and consumes only as much gas as it is set.
  • Guarantees operational stability: it ensures an absolutely constant gas flow rate at all times, regardless of whether the cylinder is full or nearly empty.

Savings in shielding gas consumption can range from a dozen to several dozen percent, depending on factors such as weld duration and the length of the gas supply hoses.

COMMON MISCONCEPTIONS
„A skilled welder can achieve the same result using a standard regulator”The rapid gas surge at arc strike is a purely mechanical phenomenon caused by a pressure spike in the hoses, which the operator simply cannot manage without the appropriate regulator.
