Hot Max Torches VTK-MD - Manual (Page 6)

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 the oxygen cylinder valve to allow
oxygen to flow to the regulator. Once the regula-
tor 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. Open slow-
ly 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 im-
portant 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: Consult the char t on page 9 for the appro-
priate tip and working pressures for the thickness of
the metal being used.
2. Open the acetylene control knob (1) on the torch
handle by turning it counter-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 counter-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 VTK-MD 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.
