KDAR Company 5
Installation & Setup
It is important that all fittings have been tightened
with a wrench by this point.
Insure the tank valves, regulators valves and torch
handle valves are turned to the off position.
Opening Valves
1. Attach the welding tip and tighten with a wrench.
2. Slowly open (clockwise) the oxygen cylinder
valve to allow oxygen to flow to the regulator.
Once the regulator begins to register pressure,
open the valve an additional 1 to 1 1/2 turns.
Note: This must be done slowly, as a surge of
pressure could damage the regulator diaphragm.
3. Slowly open the acetylene tank valve with the
tank key. This valve turns left (counter clockwise)
to open. Open slowly and not more then 1 turn.
4. Check for leaks. Leaks can not be seen, therefore,
use soapy water on all connection points to insure
there are no leaks.
Setting Working Pressures—Welding
While setting working pressure gases will
be released from the torch. It is important
that no open flame or other heat source is
present during this operation.
1. Attach the welding tip to the end of the torch han-
dle opposite the hose attachment and tighten with
a wrench.
Note: The working pressure for the welding tip sup-
plied with the Mobile Max (#1) is a minimum of 3
and maximum of 5 P.I.S.G. for oxygen and Minimum
of 3 and maximum of 5 P.I.S.G. for acetylene. If
other tips are used consult the tip charts on page 9.
2. Open the acetylene control knob (1) on the torch
handle by turning it clockwise. Turn the control
lever on the acetylene regulator until the desired
working pressure is reached. Once the working
pressure is reached turn off the control knob on
the torch handle. The regulator gauge reading
may increase slightly.
3. Open the oxygen control knob (2) on the torch
handle by turning it clockwise. Turn the control
lever on the oxygen regulator until the desired
working pressure is reached. Once the working
pressure is reached turn off the control knob on
the torch handle. The regulator gauge reading
may increase slightly.
Note: The Mobile Max is equipped with single stage
regulators and as such the working pressure may
need to be adjusted as the gas pressure in the tanks
decreases.

Prior to lighting the torch make sure the
hoses are behind the operator and that
there is no chance of them being hit by a
hot spark or slag.
