The Gas Box is fitted with 2 digital gauges. The Gas Box can be clamped safely onto the rail head by using the
clamp underneath the Gas Box.
The digital gauges provide accurate pressures with an accuracy of one thousandth of a bar. They work with a
lithium battery that can be changed via the top panel on the Gas Box
(Figure 6)
. The digital gauges are set to
switch off automatically after 5 minutes of use. This time can be modified in the settings menu.
The Hoses
There are 2 hoses, one for the Propane and one for the
Oxygen. They are connected to the gas box on one end and
connected to the torch and mixer on the opposite end. They
are 1.50 meters long and they have a 10mm diameter. It is
essential that neither of these be altered.
Self-Centring Burner
The burner head has a support that is adjustable in height
and widths to fit the range of moulds supplied by PANDROL.
The moulds have a notch where the torch support sits
(see
figure 3)
. The torch support is then secured to the moulds
by using the thumb screw. Care should be taken not to over
tighten the support as it may crack the moulds.
(See Figure
3).
