Turbulent flow pulls air into the gas shield creating excess weld spatter and inferior weld quality.  Flow rates causing  turbulent shielding can be as low as about 40 CFH depending on nozzle size!  We have measured 150 CFH with some flowmeters when the ball is pinned to the top of the flowmeter!  That is not only wasting gas but is definitely pulling air into the shielding gas stream causing excess spatter and inferior weld quality.

 

To Use Our "Flow Rate Limiter"  Simply:

  1. Set maximum flow rate desired on your flowmeter.

  2. Slip "Flow Rate Limiter" over control knob so the Pin limits further flow increases.

  3. Tighten the setscrew.  If welders are likely not to find and use the small Allen wrench supplied with the product, the FRL is all you need to purchase.

  4. To block access to the Allen screw, our FRLL model includes a Locking System that blocks setscrew access (Note: all brass locks are keyed the same.)

FLOW RATE LIMITER

 

Part Number WAT-FRLL Shown

 

Fits most popular flowmeters and regulator- flowmeters. 

 

The flowmeter on the left incorporates a typical needle valve to control gas flow rates.  A wide flow adjustment range is possible.  Unfortunately welders often use the adage that; "If some is good more must be better," when setting gas flow rates.  This not only wastes gas but creates a turbulent shielding gas stream pulling moisture laden air into the arc.

 

In most instances Model FRL  provides a sufficient deterrent to avoid changes in flow and prevents unintentional changes in settings.  A small Allen wrench (supplied with the product) is often not readily available.

A Flow Limiting Locking system is available by ordering Model FRLL.  Model FRLL includes a stainless steel Blocking Bar that slips into holes in the FRL and prevents access to the set screw.  A sold brass Lock in then inserted into a hole in the Blocking Bar to prevent its removal.  Payback can be measured in weeks from gas savings with improved weld quality a bonus.

2) The Max Flow can be set at any level desired and available with the specific flowmeter before the FRL is locked in place.

3) Valve placement in this model may require mounting with the lock up.

4) It is also possible to mount the lock up and essentially lock the flow at the desired setting.

5) It is also possible to mount the lock facing back toward the body and essentially lock the flow at the desired setting.

6) For this model the normal mounting is with the lock facing up (see photo D).

7) With the Maximum flow set at X CFH the Minimum flow will be X - the value shown.  Also see footnotes 4 and 5 since for some flowmeters the FRL can be positioned to lock the flow at the desired level and not allowing it to change up or down.

8) If it after setting the maximum desired flow, the lower flow setting is more than desired, there is a simple solution.

Fits Some Other Models

 

Victor Model HRF2325 regulator (photo left) is an old style with a plastic knob.  The knob diameter from peak to peak is larger than the 0.750 inches of the newer models and will not fit the FRL.  The peaks were simply removed with a Dermal Tool so it fit the hole in the FRL.

 

A customer reports the FRL fits a Harris Model 355 (photo Left) When set at 45 CFH max they reported being able to reduce flow down to 20 CFH.
