Unpacking Your Tool

• Carefully unpack and inspect your tool. Fully familiarise yourself with all its features and
functions
• Ensure that all parts of the tool are present and in good condition. If any parts are missing or
damaged, have such parts replaced before attempting to use this tool

Before Use

WARNING: Always unplug the welding machine from the mains supply and allow to cool fully
before attempting to fit or replace any part.
IMPORTANT: This tool is earthed and must only be connected to mains with an earth connection. Do
not attempt to use it without an earth connection.
IMPORTANT: Connecting to mains
• This welder is not supplied with a mains electrical plug because at full capacity it will draw far too
much current for a normal domestic mains plug and socket.
• A high current mains socket or terminal must be installed by a qualified and accredited
professional electrician. A 32A socket and plug conforming to IEC 60309 is recommended
• A non-socketed mains connection also requires welder connection by a qualified and
accredited professional electrician. However, a socketed connection is safer and more strongly
recommended so the welder can be safely isolated when necessary. If directly wired to mains, a
double pole, double throw isolator switch must be fitted
• The welder must be connected to a consumer unit with a built-in RCD, using a circuit protected by
an RCD
• Please refer to the Specification for details of the maximum current required by this welder
• If in any doubt, do not attempt to connect or use this welder until a professional electrician has
been consulted
WARNING: If connected to a standard domestic mains socket use with CAUTION. For European
16A sockets use up to the 78A setting only and for UK 13A mains sockets use up to 52A setting
only. Use at higher settings can damage your mains wiring and insulation and be a fire risk. It is
recommended only to use this welder on a dedicated 32A mains connection. Use on a circuit of less
than 32A at high peaks of current will repeatedly trip mains circuit breakers and fuses.
Assembling the welder
1. Align the holes in the Extended Handle (4) with the holes on the top of the Carrying Handle (1)
and securely tighten the screws (using the screws provided) (Image A) and then fit the plastic
cover
2. Align the front leg with the holes under the front of the welder if not pre-fitted and secure with
screws (Image B)
3. Fit the 2 metal brackets underneath the rear of the welder (Image C)
4. Slide the bar through the 2 brackets and fit a Wheel (15) to each end securing each Wheel with
the circlip (arrowed in Image D). It is easier if one Wheel is secured to the bar before fitting
through the brackets
Assembling the mask
1. Use the mask clips to assemble the flat-packed Welding Mask (36) into its normal shape
2. Fit the Handle (35) using the Handle Nuts (32) and Handle Bolts (33). The Handle must be inside
the Welding Mask body to protect the operator's hand from spatter
3. Ensure the Spatter Shield (30) protects the Welding Filter (29) from weld spatter. If the Welding
Filter is fitted as the external layer, it may get damaged by spatter and allow dangerous
ultraviolet light to reach the operator's eyes
4. Fit the glass assembly into the Welding Mask using the Frame Screws (34) and Frame Clips (31)
Installing wire
1. While turning clockwise pull off the Shroud (11) then unscrew the exposed Tip (10) anti-
clockwise with a spanner. Then unwind the Torch Cable (14) so it is as straight as possible and in
line with the wire feed mechanism
2. Press up on the Panel Release (16) and lower the side flap of the case
3. Turn the Spool Nut (23) anti-clockwise and remove it carefully with the Tension Spring (24) and
Spool Retainer (25)
4. Place a Wire Spool (26) over the Spool Thread (27), positioning so that the wire will feed off the
Wire Spool at the correct height for the Wire Input (20)
5. Refit the Spool Retainer, Tension Spring and Spool Nut and tighten so the spool will not unravel
on its own
6. If you need to change or turn the Upper Roller (21), so the correct size groove for the wire is in
line with the inner liner of the Torch Cable (14), remove the 2 screws of the Rollers Cover (17) and
use a spanner to remove the roller securing component (Image I), then turn or replace the roller
with the correct size
MIG/MAG Combination Gas/No Gas Welder
7. Lift the metal tension bar clear of the point of the Roller Tension Adjuster (19) and move to the
side so there is a sufficient gap between the Upper Roller and Lower Roller (18) for the wire to
feed through (Image J)
8. Carefully release the end of the wire from the Wire Spool (26) and take care not to let the wire
unravel. Ensure that the wire is straight for 75 – 100mm and is cut off cleanly with a smooth tip
that will not damage the Torch Cable liner. There must be no burrs on the wire
9. Slowly feed the wire into the end of the Wire Input (20) across the rollers and into the Torch Cable
liner. Push a little way into the liner carefully until some resistance is felt
10.Swing the metal tension bar into position, ensuring that the wire is centred in the grooves of
the upper and lower rollers. Tension can be adjusted with the Roller Tension Adjuster (19) if
necessary
IMPORTANT: The Spool Nut should only be adjusted with enough tension that will cause the spool
only to turn when the wire is feeding correctly into the Torch Cable liner and the Roller Tension
Adjuster should be adjusted so the wire will slip on the rollers if there is resistance in the Torch
Cable liner.
11.Cover the wire feeding mechanism with the flap and secure with the Panel Release (16)
12.Isolate the Earth Clamp (9) by placing on a non-metallic, non-conductive surface
13.Set the Wire Feed Speed Dial (6) to the slowest setting
14.Connect the welder to the mains power supply, switch on, and hold the Torch Handle (13)
15.Move the torch away from the machine, so that the Torch Cable is straight and in line with the
wire feed mechanism so the wire will have minimal resistance
16.Ensure that the torch is not touching anything, and squeeze the Trigger (12). The wire feed
mechanism should drive the wire through to the torch (Image H)
17.If the wire is not driven through, disconnect from the mains power supply and adjust the Roller
Tension Adjuster (19)
18.When the wire is propelled out of the end of the torch, switch off and disconnect from the mains
power supply
19.Refit the Tip and the Shroud, and trim the wire so that approximately 3mm projects from the Tip
IMPORTANT: Use clean compressed air to clean the Torch Cable liner if the wire will not feed
through.
Removing wire reel and end of wire
1. Open the side flap of the welder using the Panel Release (16) and check if the old Wire Spool
(26) is empty
2. If not empty cut the wire at the Wire Spool and loop back and secure on the Wire Spool if
intending to continue using at a later date
3. Lift the metal tension bar clear of the point of the Roller Tension Adjuster (19) and move to the
side (Image J)
4. Use a pair of pliers to draw the last of the old Wire Spool (26) out through the Tip (10) of the
torch
5. Then proceed as per instructions for 'Installing wire' above
Configuring for flux wire operation
1. For 'no gas' operation using flux wire spools the polarity of the Earth Clamp (9) and the torch
must be correct. Open the side flap of the case using the Panel Release (16)
2. On the right side the cable connections can be seen (Image G). Check that the black cable
goes to the red left positive connection and the red cable goes to the right side black negative
connection. Reverse if necessary
Configuring for gas operation
1. For 'gas' operation using non flux plain wire spools
2. The polarity of the Earth Clamp (9) and the torch must be correct. Open the side flap of the case
using the Panel Release (16)
3. On the right side the cable connections can be seen (Image G). Check that the black cable goes
to right side black negative connection and the red cable goes to the red left positive connection.
Reverse if necessary
4. A regulator is required to connect to the Ø4mm gas tube that will adapt to your chosen gas bottle
or cylinder
5. To mount a gas bottle to the rear of the welder, position the welder in the correct position before
adding the bottle. Secure the bottle securely with the strap provided (Image E) and attach the
regulator (not supplied) following the instructions provided. A typical regulator is shown in
Image F. Read all safety warnings provided with or attached to the gas bottle or cylinder
6. Do a final check for all fittings to ensure they are all satisfactory and safe
