3. 1. Wheel Assembly
3. 1. 1. Turn machine upside down, and remove the screws attached to the bottom front. Use these screws to
attach the front castor wheels.
3. 1. 2. Take the rear axle and fit a wheel to one end by placing a washer, then the wheel, a second washer
and then insert a split pin.
3. 1. 3. Pass the axle through the two brackets under the gas cylinder carrier, then fit the other washer,
wheel, washer, split pin.
3. 2. Connecting the gas cylinder
3. 2. 1. When using Argon or Argon mixtures, use the Bull Nose Adaptor. If you intend to use CO2 gas, the
regulator will fit directly onto the cylinder. Fit the Bull Nose Adaptor to the cylinder with a spanner.
3. 2. 2. Fit the gas regulator on the Bull Nose Adaptor and connect it to the machine gas hose (fig.1).
3. 2. 3. 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.
3. 3. Mobile use of welder with gas cylinder attached. The welder should only be transported with a
small or medium gas cylinder attached. Do not transport the welder with a large cylinder attached.
3. 4. Fitting a reel of wire Wire capacity: (Mild Steel). 5 - 15 kilos. ( 5 kilos for 185 )
3. 4. 1. Push reel of wire over reel holder end springs and onto reel holder ensuring the spool rotates
clockwise, with the wire drawing off reel from the top (see white arrow in fig 2). Large spools of wire
have a guide hole which must be pushed onto plastic pin located at the end of the reel holder. This
pin will stop larger reels from free wheeling.
3. 4. 2. To secure the reel of wire take the plastic spacer and identify the two cut outs at one end (fig 2a).
Place the spacer over the holder end springs and onto the reel holder ensuring the two cut outs are
facing inward toward the reel of wire (fig. 2).
3. 4. 3. Undo the wire lock screw and lift the wire feed lever up to the right (fig 2).
3. 4. 4. Straighten about 40-50mm of spool wire (do not allow wire to uncoil), and gently push wire through
the plastic guide and through the 6 or 8mm roller groove (see 6.3), and through to the torch (fig. 3).
3. 4. 5. Carefully return the tension arm and secure wire with the wire lock screw.
3. 4. 6. Remove gas cup (fig 3.4.6.a) and contact tip (b) from end of torch as follows:
a) Take torch in left hand with the torch tip facing to the right.
b) Grasp gas cup firmly in your right hand.
c) Turn gas cup clockwise only (c) and pull cup out to the right.
WARNING! do not turn gas cup anti-clockwise, as this will
damage the internal spring.
d) Unscrew copper contact tip (right hand thread) to remove.
3. 4. 7. Check welder is switched off “0”, and that the earth clamp
is away from the torch tip. Connect the welder to the mains
power supply and set the voltage switch to one.
3. 4. 8. Set the wire speed knob to position 5 or 6. Keep the
torch cable as straight as possible and press the torch switch.
The wire will feed through the torch.
3. 4. 9. When the wire has fed through, switch welder off, unplug from mains.
a) Take torch in left hand and screw contact tip back into place.
b) Grasp gas cup in right hand, push onto torch head and
turn clockwise only. Do not turn gas cup anti-clockwise, as this will
damage the internal spring.
c) Cut wire so that it is just protruding from the cup.
3. 5. Setting wire tension. (fig 4).
IMPORTANT: You must set the correct tension. Too little or too much tension will cause problematic
wire feed and result in poor welding.
3. 5. 1. Tension between rollers is checked by slowing down the wire between your fingers. If top feed roller
skids the tension is correct. Use as low a tension as possible, too high a tension will disfigure wire
and result in a blown fuse.
3. 6. Clutch adjustment. Note: It is essential that the clutch is adjusted correctly.
3. 6. 1. Once the wire is fed through the torch, switch on the machine and set the wire speed to maximum.
3. 6. 2. Depress torch switch and release quickly. If the spool overruns it indicates that the clutch is too loose.
3. 6. 3. Tighten the clutch (located in the centre of the wire spool holder fig 2) with a screwdriver and test the
machine as above until the wire stops over running.
Note: DO NOT over tighten the clutch as this will cause wire feed problems and strain the motor.
3. 7. Euro Connection. Your welder has a Euro Torch Connection. Line up pins in the torch with the
appropriate holes in the machine, push in and tighten knurled knob (fig. 5). When welding is finished
remove torch and store in a safe place. Note: damage to torches and cables is not covered by
warranty.

2. SPECIFICATIONS & INTRODUCTION
IMPORTANT: These instructions contain information you require to prepare your machine for welding, together with a maintenance and
trouble shooting section. If you have no previous experience the instructions are not intended to show you how to become a welder .
Should you have no experience, we recommend that you seek training from an expert source. Mig welding is relatively easy to perform,
but does require a steady hand and time practising under supervision with scrap metal as it is only with continued practice that you will
achieve the desired results.
INTRODUCTION: These Supermigs are compact power sources, that operate on a forced air cooling system to slow transformer heating
in order to increase the duty cycle. They also have a non live torch to prevent the risk of accidentally striking an arc. Your Supermig is
designed to operate with two diameters of welding wire: 0.6mm, & 0.8mm. The 185 will accommodate a 5kgs wire spool, whilst the 195,
220 & 235 will accommodate 5 to 15kgs wire spools. All Models are equipped with: Torch, Mini reel of 0.6mm wire, Regulator,
Gas hose.

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.
4. 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
SEALEY “PROSAF/12V OR 24V IN ORDER TO PROTECT SOPHISTICATED ELECTRONICS. ENSURE YOU HAVE READ &
UNDERSTOOD THE ELECTRICAL SAFETY INSTRUCTIONS IN CHAPTER 1.
4.1.1. 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 dealer.
4.1.2. Power switch (fig B). Set the switch to position 1 or 2 for welding up to 2mm thickness.Use settings 3,4,5,6. for thicker welds.
4.1.3. Setting the welder controls. (fig A) In principle, the lower the amperage required, the slower the wire speed. See setting
chart for voltage and corresponding wire speeds.
Note: these settings a re only a guide and will vary according to the operators experience.

4.1.4. 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.
4.1.5. To weld aluminium use: Argon gas, 0.8mm Contact Tip (AK957), 0.8mm Aluminium Wire, (MIG/2/KAL08).
4.1.6. Spot Welding. Spot welding may be carried out as shown in fig.C below.
It will be necessary to fit a spot welding gas cup. ( Sealey part No. 120/722150 )
(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.
4.1.7. Use the wire feed control in conjunction with the spot weld timer below 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.
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.
4.1.8 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. 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.
5.2. 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.
5.3. Changing Feed Roller
( IMPORTANT: Adjust the feed roller to the corresponding wire size.) There are two grooves
on the feed roller, 0.6mm and 0.8mm. Always use the groove on the outside of the roller, (the
groove nearest to you). To remove the feed roller, undo the two screws and remove the plastic
cover (fig 6). Clean and turn, or if damaged change the feed roller and replace the plastic
cover accordingly.
5.4. Contact Tip (to remove tip follow steps in 3.3.6 to replace 3.3.9 a & b very carefully).
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.
5.5. Gas Cup (to remove cup follow steps in 3.3.6. and to replace 3.3.9. a & b very carefully).
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/722307) available from your Sealey Dealer.
5.6. 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.
5.7. Changing gears
An inexperienced welder can allow spatter to build up in the tip and shroud. In severe cases this can block the feed causing gear
stripping in the drive motor. To check if the gears are worn depress the button on the torch with the set switched on. If the gears are
worn, a grating sound will be heard coming from the wire feed motor, you may also observe the feed roller vibrating instead of rotating.
Should this be the case, open the gearbox, remove the worn or damaged gears and replace with new ones.
5.8. Changing Fuses
The fuse is located on the auxiliary transformer and is mainly blown for the following reasons:
Spatter collecting in the gas cup, causing contact tip to short circuit. Wire tension is too great. A sudden surge of current.
