1. SAFETY INSTRUCTIONS

1.1. ELECTRICAL SAFETY.  WARNING! It is the user’s responsibility to read, understand and comply with the following:

You must check all electrical equipment and appliances to ensure they are safe before using. 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 requires a 30 amp supply and NO plug is fitted. You must contact a qualified electrician to

ensure a 30 amp supply is available. We recommend you discuss the installation of a industrial round
pin plug and socket with your electrician. If fitting a plug -

Ensure the unit is correctly wired and earthed
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 cable outer insulation
extends beyond the cable grip and that the grip is tight.

1.1.12. 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. The minimum section of cable required for these welders 2.5mm².

SPECIFICATION IN SECTION 3.

1.2 GENERAL SAFETY

 WARNING: Unplug from the mains power supply before performing maintenance or service.
 Ensure the welder and all cables are in sound condition and good working order.
 Replace or repair damaged parts. Use recommended parts only, unauthorised parts may be dangerous and will invalidate the warranty.
 Keep the welder clean for best and safest performance.
 Use welder in a suitable working area. Keep area clean and tidy, free from unrelated materials and ensure there is adequate lighting.
 The welder should be operated by one person only.
 WARNING! Wear safety goggles, protective clothing and welding gauntlets.
 Wear a headset if noise levels exceed 85 dbA.
 Check you have good ventilation and that air can flow freely around the welder.
 Ensure there are no flammable or combustible materials near the work area.
 Clean workpieces to avoid production of unwanted gases from coatings such as varnish, galvanising or lubricants.
 Keep children and unauthorised persons away from the work area.
 Remove ill fitting clothing, remove ties, watches, rings, and other loose jewellery and contain long hair.
 DANGER! Welder creates magnetic fields that can interfere with watches, metallic prostheses, magnetic cards, instrumentation, data

transmission devices & local telephone lines. If you have a pacemaker, consult a doctor before welding or approaching a spot welding area.

 DO NOT wear any clothing with metal accessories. Ensure there are no metallic articles in your pockets.
 DO NOT use the welder for any purpose other than that for which it is designed.
 DO NOT get the welder wet or use the welder in damp or wet locations.
 DANGER! DO NOT weld near inflammable materials - solids, liquids or gases. Do not weld on containers or other fitments that contain or

have contained liquid or gas fuels.

 DO NOT operate welder while under the influence of drugs, alcohol or intoxicating medication, or if fatigued.
 DO NOT operate the welder if it, or the cable, is damaged.
 DO NOT allow untrained persons to operate the welder.
 DO NOT use outside, welder is for inside use only.
 When not in use remove plug from power supply and store in a dry, childproof location.

2. INTRODUCTION

The SR122 is a portable spot welder with an electronic timer which enables precision spot welding on low carbon sheet steel ( using the standard
arms supplied ) up to a thickness of 1+1mm. The unit also features welding pressure adjustment. The SR123 is similar to the SR122 but has additional
features and capabilities enabling welding on low carbon sheet steel ( using the standard arms supplied ) up to a thickness of 2+2mm. The SR123 is
microprocessor controlled enabling the following functions to be selected from the control panel. A) Welding time. B) Welding thickness. C) Selection
of normal or pulse welding modes. Both units are supplied with standard 120mm arms and electrodes.
