5.0 Installation
Read entire installation section before starting installation.
SAFETY PRECAUTIONS
•
ELECTRIC SHOCK can kill.
•
Only qualified personnel should perform this installation.
•
Only personnel that have read and understood the Operating
Manual should install and operate this equipment.
•
Machine must be grounded per any national, local or other
applicable electrical regulations.
•
The MIG power switch is to be in the OFF position when
installing work cable and torch and when connecting other
equipment.
5.1 Unpacking the Machine
Cut banding and lift off cardboard carton. Cut banding holding the
machine to the skid. Remove corrugated packing material. Remove
accessories from Gas Bottle Platform.. Roll the machine off the skid
5.2 Location
Locate the welder in a dry location where there is free circulation of
clean air into the louvres in the back and out the front. A location that
minimizes the amount of smoke and dirt drawn into the rear louvres
reduces the chance of dirt accumulation that can block air passages
and cause overheating.
5.3 Input and Grounding Connection
WARNING
Before starting the installation, check that your power supply
is adequate for the voltage, amperage, phase, and frequency
specified on the Machine nameplate.
The 400 volt 50 Hz machine is supplied with a 4m input cable and
without plug, ensure that you connect a plug that is suitably rated for
the power draw of the machine and the environmental location.
Have a qualified electrician connect the input plug. For long runs
over 30m , larger copper wires should be used. The green/yellow
wire in the input cable connects to the frame of the machine. This
ensures proper grounding of the machine when the machine plug is
inserted into the receptacle.
5.4 Output Polarity Connections
The welder, as shipped from the factory, is connected for electrode
positive (+) polarity. This is the normal polarity for MIG welding.
5.5 Changing drive roll sets
1.
Turn off the power source.
2.
Release the pressure on the idle rolls by swinging the
adjustable pressure arms down. Lift the cast idle roll assembly
and allow it to sit in an upright position.
3.
Unscrew the plastic knob retaining the lower grooved drive roll
and side off the drive roller.
4.
Ensure the wire size marked on the side of the feed roller
matches the wire size to be used.
5.
Replace the drive rolls in reverse of the above procedure
ensuring the wire size to be used is marked on the outward
facing side of the roller as it is refitted.
NOTE: Be sure that the torch liner and contact tip are also sized
to match the selected wire size.

5.6 Welding wire installation
1.
Open the Wire Drive Compartment Door by lifting the 2 finger
catches on the side panel.
2.
Unscrew the plastic retaining wheel from the end of the spool
holder shaft.
3.
Position the wire spool so that it will rotate in a direction when
feeding so as to be de-reeled from the bottom of the coil.
4.
Slide the wire spool all the way onto the shaft and refit the
plastic retaining nut.
Note:- There is a friction brake on the reel hub assembly to
prevent the wire spool over running when welding stops ensure
the this is slackened to the minimum setting. I can be adjusted
by means of the nut visible when the plastic nut is removed.
5.
Turn the Spool until the free end of the electrode is accessible.
While securely holding the electrode, cut off the bent end and
straighten the first six inches. (If the electrode is not properly
straightened, it may not feed properly through the wire drive
system Manually feed the wire from the wire reel and through
the wire guide and then over the top of the wire feed rollers
(ensure the pressure arms are in the raised position.)
6.
Continue to feed the wire through the outlet guide until 20mm of
wire is protruding from the front of the machine torch connector.
7.
Reposition the adjustable pressure arms to there original
position to apply pressure. Adjust pressure as necessary.
Note:- the pressure arm should be adjusted in order to give
the minimum amount of pressure on the wire to allow reliable
feeding,
