|Using a Spool Gun?,
You may be able to reduce Shielding
Gas use by more
improving weld starts!!
|Spool Gun Construction
Some Spool Guns (those holding 1 or 2 pound spools of wire) use a gas valve located in the torch and have
a separate gas hose that can be as large as 1/4 inch ID. An
example is shown below:
This can leave up to 40 feet of large gas hose to produce
gas surge at the weld start. That will create less than optimum
starts and can cause weld start porosity or blackened weld surface.
It also wastes a great deal of
gas per start.
Company making aluminum trailers uses Miller SpoolmaticR
40 foot long Spool Guns. They knew they were wasting shielding gas and
the high start gas surge was causing weld defects. They purchased sufficient
amounts of our patented Gas Saver System hose
and fittings to outfit all their welders! Interested?
|Gas Saver System Solution
The Gas Saver System solves the starting and waste problems and will very
quickly pay for itself. You can purchase a fitted hose with a splice connection (fitting
upper left in photo below)
for the Spool Gun end of the Gas Saver System hose which includes a built-in
surge flow restrictor and a standard CGA 032 fitting for the gas supply end.
The existing gas delivery hose is cut 6 to 12 inches from the gun and the
Then Email Length Needed
Most versions of the Miller SpoolmaticR
15A or 30A use a small gas fitting on the gun end.
We have a special fitting that replaces the hose fitting
in the gun and includes a restrictor to limit surge flow velocity (fitting on
lower right of photo.) Please
