1.
Set gas cylinder on rear platform of the machine. Hook chain in
place to secure cylinder to rear of welder.
2.
Remove the cylinder cap. Inspect the cylinder valve for
damaged threads, dirt and dust. For cylinders having an
external thread fitting, remove any dust and dirt from the
threads with a clean cloth.
DO NOT ATTACH THE REGULATOR/FLOWMETER IF
OIL, GREASE OR CYLINDER VALVE DAMAGE IS
PRESENT. OIL OR GREASE IN THE PRESENCE OF
HIGH PRESSURE OXYGEN IS EXPLOSIVE! Inform your
gas supplier of this condition.
3.
Stand to one side away from the outlet and open the
cylinder valve for an instant. This blows away any dust or
dirt which may have accumulated in the valve outlet.
4.
Inspect the regulator/flowmeter for damaged threads and
seals, dirt and dust. Remove dust and dirt with a clean
cloth.
DO NOT USE THE REGULATOR/FLOWMETER IF
DAMAGE IS PRESENT! Have an authorised repair station
repair any damage.
5.
Attach the regulator/flowmeter to the cylinder valve and
tighten the union nut(s) securely with a spanner.
6.
Attach the machines inlet gas hose to the outlet fitting of the
regulator/flowmeter, and tighten the union nut securely with
a spanner.
7.
Before opening the cylinder valve, turn the regulator
adjusting knob counter-clockwise until the adjusting spring
pressure is released.
8.
Open the cylinder valve slowly a fraction of a turn. When
the cylinder pressure gauge pointer stops moving, open the
valve fully.
9.
The regulator/flowmeter is adjustable. Set it for the flow rate
recommended for the procedure and process being used
before starting to weld.
1.4 Gun and Cable Installation
The REDI-MIG 4 MIG gun and cable provided with the
machine has a factory fitted 0.9-1.2mm liner and a 1.2mm
contact tip.
1. Lay the cable out straight.
2. Make sure all pins on the gun cable connector are
aligned with the proper mating sockets on the front
panel gun connector and then join the connectors and
tighten the hand nut on the gun cable connector.
Note: If a gun and cable other than the supplied gun is to
be used, it must conform to standard European-style
connector specifications. See diagram under.
The gun trigger switch must be capable of switching 10
milliamps at 60 volts DC—resistive.
1.5 Output Polarity Connection
The REDI-MIG 4D is connected to the REDI-MIG 455
Remote power source via a control/ electrode/gas cable
assembly. The electrode cable is connected to the required
female Twist-Mate terminal on the front of the REDI-MIG
455 Remote power source.
The control cable connects to the plug on the front panel
between the positive and negative output connections of
the REDI-MIG 455 Remote power source.
The gun polarity can be changed by placing the electrode
cable to the required output connection on the front of the
REDI-MIG 455 Remote Power Source eg. for electrode (-
)ve, connect the electrode cable to the (-)ve output
connection.
Connect the work lead to the other output connection.
(See connection diagrams Page 11).
Each output connection is a Twist-Mate terminal. To
connect the output terminals, insert the correct mating
Twist-Mate plug and twist clockwise to secure. Twist anti-
clockwise and pull gently to release the Twist-Mate plug.
Gas under pressure is explosive. Always keep gas
cylinders in an upright position and always keep chained
to undercarriage or stationary support. Refer “Safety in
Welding and Cutting” - ANSI Standard Z49-1 and WTIA
Technical Note 7 available from the Welding Technology
Institute of Australia.
WARNING
Never stand directly in front of or behind the
regulator/flowmeter when opening the cylinder valve.
Always stand to one side.
WARNING
The gun trigger switch connected to the gun trigger
control cable must be a normally open, momentary switch.
The terminals of the switch must be insulated from the
welding circuit. Improper operation of, or damage to, the
machine might result if this switch is common to an
electrical circuit other than the machine trigger circuit.
CAUTION
Turn the welder power switch off before installing gun and
cable.
WARNING
Turn the welder power switch off before changing polarity.
WARNING
Be sure to keep your face away from the valve outlet when
“cracking” the valve.
