1. SAFETY
1.1. ELECTRICAL SAFETY
WARNING! It is the owner’s responsibility to read, understand and comply with the following:
You must check all electrical equipment and appliances to ensure that they are safe before use. You must inspect power supply leads,
plugs and all electrical connections for wear and damage. You must ensure the risk of electric shock is minimised by the installation of
appropriate safety devices. An RCCB (Residual Current Circuit Breaker) should be incorporated in the main distribution board. We also
recommend that an RCD (Residual Current Device) is used with all electrical products. It is particularly important to use an RCD with
portable products that are plugged into an electrical supply not protected by an RCCB. If in doubt consult a qualified electrician. You
may obtain a Residual Current Device by contacting your Sealey dealer. You must also read and understand the following instructions
concerning electrical safety.
1.1.1. The Electricity At Work Act 1989 requires all portable electrical appliances, if used on business premises, to be tested by a qualified
electrician, using a Portable Appliance Tester (PAT), at least once a year.
1.1.2. The Health & Safety at Work Act 1974 makes owners of electrical appliances responsible for the safe condition of the appliance
and the safety of the appliance operator. If in any doubt about electrical safety, contact a qualified electrician.
1.1.3. Ensure the insulation on all cables and the product itself is safe before connecting to the mains power supply. See 1.1.1. & 1.1.2.
above and use a Portable Appliance Tester (PAT).
1.1.4. Ensure that cables are always protected against short circuit and overload.
1.1.5. Regularly inspect power supply, leads, plugs for wear and damage and all electrical connections
to ensure that none is loose.
1.1.6. Important: Ensure the voltage marked on the product is the same as the electrical power supply
to be used and check that supply is correctly fused, see fuse rating at right.
1.1.7. DO NOT pull or carry the powered appliance by its power supply lead.
1.1.8. DO NOT pull power plugs from sockets by the power cable.
1.1.9. DO NOT use worn or damaged leads, plugs or connections. Immediately replace or have
repaired by a qualified electrician.
1.1.10. This product comes without a plug. You must contact a qualified electrician to ensure an
adequate supply is available.
If fitting such a plug -
Ensure that the unit is correctly wired and earthed, as follows:
a) Connect the GREEN/YELLOW earth wire to the earth terminal ‘E’.
b) Connect the BROWN live wire to live terminal ‘L’.
c) Connect the BLUE neutral wire to the neutral terminal ‘N’.
d) After wiring, check there are no bare wires, that all wires have been correctly connected,
that the cable outer insulation is clamped by the cable grip and that the grip is tight.
1.1.11. Cable extension reels. When a cable extension reel is used it should be fully unwound before connection. A cable reel with an RCD
fitted is recommended since any product which is plugged into the cable reel will be protected. The section of the cores of the cable is
important. 2.5mm² section is a minimum, but to be absolutely sure that the capacity of the cable reel is suitable for this product and
for others that may be used in the other output sockets, we recommend the use of 2.5mm² section cable.

4. ASSEMBLY & PREPARATION
4.1. ASSEMBLING GAS PLATFORM: (Refer to ‘P’ in figs.1 & 2) Turn the welder upside down on a smooth non-abrasive surface. The
welder should be turned over by two people as it is very heavy.
4.1.1. The gas platform is held in place with 7 M6 x 10mm bolts requiring a 10mm spanner. The casing has pre-prepared threaded inserts
ready to take the fixings. Place the platform onto the base of the welder with the axle uppermost and fix in place with 3 bolts. See (X)
in fig.1 below.
4.1.2. Insert the remaining four bolts through the two fixing flanges laying on the back of the welder. See (X) in fig.2. Finally, tighten all 7
bolts.
4.2. ASSEMBLING THE WHEELS: (Refer to fig.1)
4.2.1. Slide a wheel (Y) over each end of the solid axle attached to the gas platform. Slide a washer over each end of the axle and insert a
split pin (Z) through the hole in each end of the axle and bend it over to retain the wheels.
4.2.2. Bolt the two castors (W) to the front end of the base using the 8 bolts provided. The casing has pre-prepared threaded inserts ready to
take the fixings. See fig.1.
4.2.3. With the assistance of another person turn the welder the right way up onto its wheels.
4.2.4. The Gas Cylinder Bracket (Item 36 see parts diagram) can be found stored inside the wire feed compartment, in the top corner above the
wire feed assembly. Remove from this location and fix to the rear of the machine.
4.3. ASSEMBLING THE EARTH CLAMP: (Refer to fig.3) Feed the eyelet on the end of the earth lead through the
hole in the clamp arm as shown in fig.3A.
4.3.1. Drop the eyelet over the terminal and firmly fix with the bolt provided as shown in fig.3B.
4.4. INSTALLING THE GAS CYLINDER. The welder is designed to accommodate small or medium sized
gas cylinders up to a maximum height of 1000mm. Contact your local Gas dealer for supply.
4.4.1. Place the gas cylinder onto the rear platform of the welder. See fig.2-P. Place one end of the fixing chain
into one side of the retaining bracket. Draw the chain around the cylinder and place it into the slot on
the other side of the bracket leaving as little slack in the chain as possible.
4.5. ATTACHING THE REGULATOR. Whichever gas you are using it is advisable to ‘crack’ the cylinder valve before attaching the regulator.
This means opening and closing the valve very quickly in order to blow away any dust and dirt that may have accumulated in the gas
outlet. Stand to one side whilst doing this.

5. MIG/MAG WELDING
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.
5.1. 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.
5.2. CONNECTING THE EARTH LEAD.
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 stockist.
5.2.1. 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.
5.2.2. 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.
5.2.3. Welding mild steel.
To weld mild steel you can use CO² 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/CO² mixture.
5.2.4. To weld aluminium use:
✓ Argon gas,
✓ 0.8mm Contact Tip,
✓ 0.8mm Aluminium Wire,
5.3. OVERLOAD PROTECTION.
5.3.1. 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
5.3.2. 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
may be employed.
5.3.3. 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 operators
experience.

6. RATINGS PLATE
On the front of the welder is the ratings plate, giving the
following data:
1 - The standard relating to the safety and construction
of arc welding and associated equipment.
2 - Single phase transformer - rectifier.
3 - Welding with a continuous flow of welding wire.
4 - Single-phase AC supply.
5 - Rating of internal protection provided by casing.
6 - Output
U0: Rated minimum & maximum no load voltage.
I2, U2: Current and corresponding voltage.
X: Welding ratio based on a 10 minute cycle. 20% indicates 2 minutes welding and 8 minutes rest, 100% indicates continuous welding.
7 - Mains Supply U1: Rated supply voltage and frequency. Imax: Maximum current. I1eff: Maximum effective current.
8 - Welding current range.
9 - Serial Number. Specifically identifies each welder. (example shown).
7. MAINTENANCE
7.1. WIRE FEED UNIT Check the wire feed unit at regular intervals. The feed roller wire guide plays an important part in obtaining consistent
results. Poor wire feed affects welding. Clean the rollers weekly, especially the feed roller groove, removing all dust deposits.
7.2. TORCH Protect the torch cable assembly from mechanical wear. Clean the liner from the machine forwards by using compressed air. If
the liner is clogged it must be replaced.
7.3. CHANGING FEED ROLLER (See Section 4.12)
7.4. CONTACT TIP The contact tip is a consumable item and must be replaced when the hole becomes enlarged or oval. The contact
tip MUST be kept free from spatter to ensure an unimpeded flow of gas. Refer to fig.11 and section 4.9.4 to 4.9.7 for removal and
replacement.
7.5. GAS CUP The gas cup must also be kept clean and free from spatter. Build up of spatter inside the gas cup can cause a short circuit
at the contact tip which will result in either the fuse blowing on the printed circuit card, or expensive machine repairs. To keep the contact
tip free from spatter, we recommend the use of Sealey anti-spatter spray (MIG/722308) available from your Sealey Stockist. Refer to
fig.11 and section 4.9.4 to 4.9.7 for removal and replacement.
7.6. REPLACING THE LINER Wind the wire back on to the spool and secure it. Unscrew the torch from the machine and undo the brass
nut. The liner should now be visible. Pull it out and replace with a new one.
