The user of this welder is responsible for his own and the safety of others. It is most important to read, learn and respect the rules in this user guide.When using this welder, basic safety precautions, including the following, should be followed to reduce the risk of fire, electric shock and personal injury. Make sure that you have read all of these instructions before using this welder. Keep this booklet in a safe place for future reference. Persons who are not familiar with this booklet should not use the welder.

WARNING! SAFETY INSTRUCTIONS

TRAININGThe operator should be properly trained to use the welding machine safely and should be in-formed about the risks relating to arc welding procedures. This manual does not attempt to cover welding technique. Training should be sought from qualified/experienced personnel on this as-pect especially for any welds requiring high integrity for safety.

SERIOUS FIRE RISKThe welding process produces sparks, droplets of fused metal, metal projectiles and fumes. This constitutes a serious fire risk. Make sure that the area around the work piece is clear of all inflam-mable materials. It is advisable to have a fire extinguisher to hand.

WORK AREAEnsure a clear work area with unrestricted movement for the operator. Always maintain easy ac-cess to the On/Off switch and the mains supply.

THE WORK PIECEThe work piece will remain at a high temperature for a relatively long period. Do not touch the weld or the work piece unless you are wearing welding gloves. Always use pliers or tongs. Never touch the welded material with bare hands until it has been allowed to cool.

WELDING SURFACESDo not weld on containers or pipes that hold, or have held, flammable liquids or combustible gases. Do not weld coated, painted or varnished surfaces as the coatings may ignite and or can give off dangerous fumes.

VENTILATE THE WORK AREAArc welding (especially using fluxed core wire) emits fumes which can be dangerous. Make sure that the work area is well ventilated.

AVOID ELECTRICAL CONTACTUse adequate electrical insulation with regard to the electrode, the work piece and any accessi-ble) earthed metal parts in the vicinity. Avoid direct contact with the welding circuit. The no load voltage between the earth clamp and the torch can be dangerous under certain circumstances.

FOR ADDITIONAL PROTECTION FROM ELECTRIC SHOCKIt is recommended that this tool be used in conjunction with a residual current device (RCD)with a rated residual current of 30mA or less.

CONSIDER WORK AREA ENVIRONMENTDo not expose the welder to rain. Do not use it in damp, or wet locations. Keep the work area well lit.

SAFETY INSTRUCTIONS … cont

DRESS PROPERLYUse protective gloves and fire resistant protective clothing when using the welder. Avoid exposing skin to the ultraviolet rays produced by the arc.

ALWAYS USE THE WELDING MASKUnder no circumstances should the welder be operated unless the welding mask is protecting the eyes and face. There is a serious risk of eye damage if the mask is not used. The sparks and metal projectiles can cause serious damage to the eyes and face. The light radiation produced by the arc can cause damage to eyesight and burns on the skin. Never remove the welding mask whilst welding. Move the torch away from the work piece and release the trigger switch before removing the welding mask. SAFETY GLASSESAfter welding use safety glasses when brushing, chipping grinding the slag from the weld.

OTHER PERSONSEnsure that other persons are screened from the welding arc and are at least 15 metres away from the work piece. Always ensure that the welding arc is screened from onlookers, or people just passing by. Use screens if necessary, or non reflecting curtains.

KEEP CHILDREN AND ANIMALS AWAYDo not let children or animals have access to the welding equipment or to the work area.

SWITCHING OFFWhen you have finished welding switch off the welder. Do not put the torch down with the welder switch On and with the wire fitted. When leaving the welder unattended, move the On/Off switch to the Off position and disconnect the welder from the mains supply. Do not leave hot material unattended after welding.

WELDING CABLESKeep the welding cables, earth clamp and torch in good condition. Failure to can result in poor welding quality and could be dangerous in structural situations.

CHECK DAMAGED PARTSBefore further use of the welder, any part that is damaged should be carefully checked to deter-mine that it will operate properly and perform its intended function. Check for breakage of parts and any other conditions that may affect its operation. Any part that is damaged should be prop-erly repaired, or replaced, by an authorised service centre.IMPROPER USEDo not use this welder for pipe thawing.HANDLING Ensure the handle is correctly fitted and always use safe lifting practices when lifting.

CAUTION! - VENTILATE THE WELDER

THERE must always be a sufficient air passage around the welder to allow for the cooling of the transformer. If the cooling process is obstructed the welder will overheat and the overload

cut out protector will activate and cut off the welding current. If the overload cut out protector activates leave the welder for at least 15 minutes to cool down before further use.

ADDITIONAL PRECAUTIONS

WELDING OPERATIONS: In environments with increased risk of electric shock; In confined spaces; In the presence of flammable or explosive materials;

MUST BE evaluated in advance by an “expert supervisor” and must always be carried out in the presence of other people trained to intervene in emergencies.

POSITION and HANDLINGPosition the welding machine on a horizontal surface that is able to support the weight: otherwise (e.g. inclined or uneven floors etc.) there is danger of overturning.

The welder MUST NOT be supported by the operator (e.g using belts).The operator MUST NOT BE ALLOWED to weld in raised positions unless safety plat-forms are used.

VOLTAGE BETWEEN ELECTRODE HOLDERS OR TORCHES:Working with more than one welding machine on a single piece or on pieces that are connected may generate a dangerous accumulation of no-load voltage between two different electrode holders or torches, the value of which may reach double the allowed limit.

IMPROPER USE:It is hazardous to use the welding machine for any work other than that for which it was designed. Example do not use this welder for pipe thawing. The safety guards and moving parts of the covering of the welding machine and of the wire feeder should be in their proper positions before connecting the welding machine to the power supply.

WARNING!Any manual operation carried out on the moving parts of the wire feeder, for example:Replacing rollers and/or the wire guide; Inserting wire in the rollers; Loading the wire reel;Cleaning the rollers and the area underneath them.

Should be carried out with the welding machine switched off and disconnected from the power supply outlet . Never lift the welding machine when connected to the mains supply.

ARC WELDING PROCEDURE1) Select MMA mode [9]2) Set welding current [4] to suit the job at hand.

Before commencing, make sure that your hand held welding mask or welding helmet is in position to protect your eyes. It is also advisable to wear gloves and clothing, which cover the hands and arms to prevent flash burns.

Striking Arc. This is done by bringing the electrode into contact with the work piece using a light tap-ping action and withdrawing to create a gap of (1.5 mm – 3.00 mm.).

Maintaining Arc. Having created an arc, all that is necessary to maintain it is to proceed steadily in one direction keeping the gap between the electrode and the work piece constant. The electric current will flow through the electrode, across the arc gap, and in doing so will melt the electrode core wire and protective flux. The electrode length will gradually decrease as the metal is transferred to the work piece under a protective slag formed by the flux. This slag can then be removed when cooled by lightly tapping with a pointed tool or a welders chipping hammer.

To stop welding, all that is required is to withdraw the electrode from the work piece - thus break-ing the circuit. Be careful with the end of the electrode, as it will be hot! Provided the current setting is correct, the surface of the work piece will also melt by the intensity of the electric arc. A degree of “penetration” is thereby obtained and a complete “fusion” of the work piece and the deposited elec-trodes met

Selection of electrode. There is no hard and fast rule by which a particular gauge of electrode is select-ed. Usually this is determined by, the type of weld required and the thickness of the work piece. E.g. a butt weld in (1.5mm.) sheet metal can be done by a 1.6mm or 2.5mm electrode, the difference being that the 2.5mm electrode will do the job quicker. The table below Gives guidance as to which elec-trode is most suitable according to the material thickness. This table is only a guide, and values given are an indication only.

Tip! Keep the welding current as low as possible for the job at hand to maintain the best duty cycle from you welding machine, prevent the flux from burning and make removal of slag easier.

CAUTION! When fitting the welding leads to the unit, twist the plugs clock-wise and ensure that they are tight in the sockets. Loose connec-tors will overheat, damage the unit and void warranty.
