GENERAL DESCRIPTION This welder is a power source for light duty manual arc welding only. It has been designed and manufactured specifically for continuous MIG welding of carbon or mild steels with and without protective gas using appropriate cored (tubular) electrode wire or solid wire. Power for the arc is given by a single phase transformer with a drooping characteristic. It is suitable for use with 0.6/0.9mm solid or 0.8/0.9mm core wire and for welding materials up to 8mm. PRODUCT SPECIFICATION Note: This welder requires a 15 mains supply.

It is most impor- tant 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 ref- erence. Persons who are not familiar with this booklet should not use the welder. TRAINING The 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 aspect especially for any welds requiring high integrity for safety. SERIOUS FIRE RISK The 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 inflammable materials. It is advisable to have a fire extinguisher to hand. WORK AREA Ensure a clear work area with unrestricted movement for the operator. Always maintain easy access to the On/Off switch and the mains supply. THE WORK PIECE The 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. WARNING! SAFETY INSTRUCTIONS VENTILATE THE WORK AREA Arc welding (especially using fluxed core wire) emits fumes which can be dangerous. Make sure that the work area is well ventilated. WELDING SURFACES  Do not weld on containers or pipes that hold, or have held, flammable liquids or com- bustible gases.  Do not weld coated, painted or varnished surfaces as the coatings may ignite and or can give off dangerous fumes. CONSIDER WORK AREA ENVIRONMENT Do not expose the welder to rain. Do not use it in damp, or wet locations. Keep the work area well lit. AVOID ELECTRICAL CONTACT Use adequate electrical insulation with regard to the electrode, the work piece and any acces- sible) 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 circum- stances. EXTENSION LEADS In general these are best avoided. If used however make sure that the extension lead used with the welder is of a suitable current rating and has an earth connection. If using the welder outdoors make sure that the extension cable is suitable for outdoor use. Always keep cables and extension leads away from the welding zone and any hot materials. FOR ADDITIONAL PROTECTION FROM ELECTRIC SHOCK It is recommended that this tool be used in conjunction with a residual current device (RCD) with a rated residual current of 30mA or less. Page 4 RXT175P SAFETY INSTRUCTIONS … cont CHECK DAMAGED PARTS Before further use of the welder, any part that is damaged should be carefully checked to de- termine 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 properly repaired, or replaced, by an authorised service centre. ALWAYS USE THE WELDING MASK Under 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 pro- duced 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 trig- ger switch before removing the welding mask. SAFETY GLASSES After welding use safety glasses when brushing, chipping grinding the slag from the weld. OTHER PERSONS Ensure 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 peo- ple just passing by. Use screens if necessary, or non reflecting curtains. KEEP CHILDREN AND ANIMALS AWAY Do not let children or animals have access to the welding equipment or to the work area. SWITCHING OFF When 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 CABLES Keep 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. DRESS PROPERLY Use protective gloves and fire resistant protective clothing when using the welder. Avoid ex- posing skin to the ultraviolet rays produced by the arc. 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. IMPROPER USE Do not use this welder for pipe thawing. HANDLING Ensure the handle is correctly fitted and always use safe lifting practices when lifting.
