6.0 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.
6.2 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.
6.3 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 230 volt 50 Hz machine is supplied with a 2m 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.
Using the, 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.
6.4 Output Polarity Connections
The welder, as shipped from the factory, is connected for electrode
positive (+) polarity. This is the normal polarity for MIG welding with
Gas. If you are welding with gasless wire release the polarity
6.5 Changing drive roll sets
1. Turn off the power source.
2. Release the pressure on the idle roll by swinging the adjustable
pressure arm down toward the back of the machine. 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 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.
6.6 Welding wire installation
1.
Open the Wire Drive Compartment Door by lifting the 1 finger
catch 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.
5.
If you are using 5kg spool fit the spacer bush before the
lock 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.
