1. SAFETY
1.1. ELECTRICAL SAFETY
WARNING! It is the responsibility of the owner and the operator to read, understand and comply with the following:
You must check all electrical products, before use, to ensure that they are safe. You must inspect power cables, plugs, sockets and
any other connectors for wear or damage. You must ensure that the risk of electric shock is minimised by the installation of
appropriate safety devices. A Residual Current Circuit Breaker (RCCB) should be incorporated in the main distribution board.
We also recommend that a Residual Current Device (RCD) is used. It is particularly important to use an RCD with portable
products that are plugged into a supply which is not protected by an RCCB. If in any doubt consult a qualified electrician. You may obtain
a Residual Current Device by contacting your Sealey stockist. You must also read and understand the following instructions concerning
electrical safety.
1.1.1. The Electricity at Work Act 1989 requires that all portable electrical appliances, if used on business premises, are 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 those appliances and
the safety of the appliance operators. If in any doubt about electrical safety, contact a qualified electrician.
1.1.3. Ensure that the insulation on all cables and on the appliance is safe before connecting it to the power supply. See 1.1.1. and and use a
Portable Appliance Tester.
1.1.4. Ensure that cables are always protected against short circuit and overload.
1.1.5. Regularly inspect power supply cables and plugs for wear or damage and check all connections to ensure that none is loose.

4.5. 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.
4.5.1. Place the gas cylinder onto the rear platform of the welder. See
fig.2-P.
4.5.2. 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.
4.6. 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.
4.6.1. CO²GAS. Ensure that the threads on the gas bottle are undamaged and free of oil and grease before attaching the regulator. (Oil or
grease in the presence of high pressure gases can be explosive). Ensure that the regulator has an undamaged gasket fitted. The
regulator will screw directly to the threads on the gas bottle. Tighten with a spanner.
4.6.2. ARGON GAS OR ARGON MIXTURES.Cylinders containingArgon gas andArgon mixtures have a female thread and will require the use
of a Bull Nose Adaptor to attach the regulator to the cylinder as indicated in fig.4. Ensure that the threads on the gas bottle are
undamaged and free of oil and grease before attaching the regulator. (Oil or grease in the presence of high pressure gases is explosive).
Fit the Bull Nose Adaptor to the cylinder first and tighten with a spanner. Ensure that the regulator has an undamaged gasket before
fitting onto the Bull Nose Adaptor. Tighten with a spanner.
4.6.3. Slide a clip over each end of the gas hose supplied. Push one end of the hose onto the regulator outlet and the other end over the gas
inlet spigot on the back of the welder. See fig.2G. Tighten the clips to ensure a good seal.
4.6.4. Close the regulator valve by turning it anti-clockwise before opening the cylinder valve. Stand to one side when opening the cylinder
valve.
4.6.5. Set the regulator flow rate to 5-8 litres/min depending on the material to be welded, and whether there are draughts which are
strong enough to disturb the gas flow.
4.7. CONNECT THE TORCH CABLE TO THE WELDER.
4.7.1. Align the pins on the Euro connector with the socket on the welder
front panel as shown in g.5. Push the connector into the socket

5. a MIG/MAG WELDING
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.
5.1. PREPARATION FOR WELDING
IMPORTANT: BEFORE YOU COMMENCE, MAKE SURE THE MACHINE IS SWITCHED OFFAT THE MAINS. IF WELDINGA CAR,
DISCONNECT THE BATTERY OR FITAN 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.
5.1.1. 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
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 CO²gas 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/CO²mixture.
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.

6. a 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.
7. a 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 3.12)
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 3.9 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.12 and section
3.9 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.
