with the key and slide the roller back onto the carrier.

MIG/MAG WELDING
a
5.13.1.
A spool of welding wire is positioned on the welder's spool holder and automatically
fed through an insulated liner in the torch to the tip. The torch assembly consists of a
switch, liner, gas hose, and control cable. The switch activates the wire feed roller and the gas flow.
Conversely, releasing the switch stops the wire feed and gas flow. The weld current is transferred to
the electrode (the wire) from the contact tip at the end of the torch. A gas cup fits over the contact tip
to direct the gas flow towards the weld ensuring that the arc welding process is shielded from oxidising air contaminates. The shielding
gas also assists heating of the weld materials. The torch is connected to the positive side of a DC rectifier, and the negative clamp is
attached to the workpiece.
IMPORTANT: Should you have no welding experience, we recommend you seek training from an expert source to ensure your
personal health & safety. Good Mig welding may be achieved only with continued, supervised practice.

PREPARATION FOR WELDING
IMPORTANT: BEFORE YOU COMMENCE, MAKE SURE THE MACHINE IS SWITCHED OFF AT THE MAINS. IF WELDING A CAR,
DISCONNECT THE BATTERY OR FIT AN ELECTRONIC CIRCUIT PROTECTOR. WE STRONGLY RECOMMEND THE USE
OF A Sealey "PROSAF/12V OR 24V IN ORDER TO PROTECT SOPHISTICATED ELECTRONICS. ENSURE YOU HAVE READ &
UNDERSTOOD THE ELECTRICAL SAFETY INSTRUCTIONS IN CHAPTER 1.
NOTE! When welding on a tilted plane ensure the welder is stable and is not in danger of falling over. Ensure the welder is sufficiently
secured.
Connecting the Earth Lead
5.1.1.
To ensure a complete circuit, the earth lead must be securely attached to the work piece that is to be welded.
a) Best connection is obtained by grinding clean the point of contact on the workpiece before connecting the earth clamp.
b) The weld area must also be free of paint, rust, grease, etc.
c) When welding a vehicle, be sure the vehicle battery is disconnected or fit an Electronic Circuit Protector available from your Sealey
stockists.
5.1.2.
Power Output switch
Set the switch to position 1 or 2 for welding up to 2mm thickness. Use settings 3,4,5,6. for thicker welds.
5.1.3.
Setting the welder controls In principle, the lower the amperage required, the slower the wire speed. See setting chart below for
voltage and corresponding wire speeds. Note: these settings are only a guide and will vary according to the operator's experience.
5.1.4.
Welding mild steel
To weld mild steel you can use CO ² gas for most tasks where spatter and the high build up of weld do not pose
a problem. Welding with a long arc reduces penetration and widens the arc. This in turn results
in more spatter. A long welding arc can be appropriate for welding butt joints in thin materials. Welding with a
short arc, at the same weld settings, results in greater penetration and a narrower weld and reduces the amount
of spatter. To achieve a consistent spatter free and flat weld, you must use an Argon/CO
To weld aluminium use:
Argon gas,
0.8mm Contact Tip,
0.8mm Aluminium Wire,
5.1.5.
Overload Protection
Thermostatic overload protection is provided. When an overload has
occurred, leave the unit to cool. The thermostat will automatically
reset the unit when the temperature has returned within limits.
5.1.6.
Spot Welding
Spot welding may be carried out as shown in fig.16. It will be necessary
to fit a spot welding gas cup.
(a) Overlapping metal sheets with a maximum thickness of 0.8 mm may be
welded as indicated.
(b) Alternatively they may be welded edge to surface as indicated.
(c) For thicker sheet pre drilled holes holes may be employed.
5.1.7.
Use the wire feed control in conjunction with the spot weld timer beside it.
To activate the timer turn the knob clockwise. The settings
indicated in the black portion of the chart are for guidance only and may vary
with operator's experience.
