Reducing
Flow Rate Limiter
Allowable Flow Range
Some users found that once the maximum flow level was
set, the range of allowable minimum flow was more than
desired. This is usually not a problem since welders seldom use
too little flow. However this can easily be adjusted:
-
First try the FRLL with the Lock
facing upward. Depending on the flowmeter model that may reduce flow change
range
or even lock the flow rate.
-
Another simple approach to limit the flow
adjustment range is to install a short
piece of 3/16 ID tubing over the stainless steel pin attached to the
billet aluminum body (see photo below.) This will limit the amount the
flow knob can turn. A small dab of glue on the stainless pin surface will
make it difficult to remove the added tubing. If the tube or hose wall thickness used is too thin
another piece of larger ID//OD hose can be glued in place over the first.
