Safety Info SAFETY INFO AND TIPS WARNING PROTECT YOURSELF AND OTHERS FROM POSSIBLE SERIOUS INJURY OR DEATH .KEEP CHILDREN AWAY. IF WEARING A PACEMAKER KEEP AWAY UNTIL CONSULTING YOUR DOCTOR. DO NOT LOSE THESE INSTRUCTIONS. READ OPERATING/INSTRUCTION MANUAL BEFORE INSTALLING, OPERATING OR SERVICING THIS EQUIPMENT. Welding products and welding processes can cause serious injury or death, damage to other equipment or property, if the operator does not observe all safety rules and take precautionary measures.

SAFETY PRECAUTIONS FOLLOW THE BELOW PRECAUTIONS CAREFULLY. IMPROPER USE OF ANY WELDER MAY RESULT IN SERIOUS INJURY OR DEATH. ONLY CONNECT WELDER TO A POWER SOURCE FOR WHICH IT IS DESIGNED. The specification plate on the welder lists this information.When welding outdoors, only use an extension cord which is designed for outdoor use.

ARC RAYS FIRE & EXPLOSIONS ARC RAYS can burn eyes and skin; NOISE can damage hearing. The WELDING operation can potentially cause fire or an ARC RAYS from the welding process produce an intense heat explosion as Sparks and spatter are emitted from thewelding and strong ultraviolet rays that can burn eyes and skin.

Getting Started WELDING 101 MIG/MAG Welding Technique For those who have not yet done any welding, the simplest way to commence is to run beads on a piece of scrap plate. Use a mild steel plate, around 6mm thick and a 3.2mm electrode. Clean any paint, loose scale or other contaminants from the plate, and set it firmly on the workbench so that welding can be carried out in the downhand position.

FLUXCORED ARC WELDING(FCAW): This is an electric arc welding process which fuses together the parts to be welded by heating them with an arc between a continuous flux filled electrode wire and the work. Shielding is obtained through decomposition of the flux within the tubular wire.
Page 12
Distance from the MIG Torch Nozzle to the Work Piece The electrode wire stick out from the MIG Torch nozzle should be between 10 and 20.0mm. This distance may vary depending on the type of joint that is being welded. Travel Speed The speed at which the molten pool travels influences the width of the weld and penetration of the welding run.
Nozzle Angle This refers to the position of the welding gun in relation to the joint. The transverse angle is usually one half the included angle between plates forming the joint. The longitudinal angle is the angle between the centre line of the welding gun and a line perpendicular to the axis of the weld.

Electrode Wire Size Selection The choice of Electrode wire size and shielding gas used depends on the following • Thickness of the metal to be welded • Type of joint • Capacity of the wire feed unit and Power Source •...

Arc Length The securing of an arc length necessary to produce a neat weld, soon becomes almost automatic. You will find that a long arc produces more heat. A very long arc produces a crackling or spluttering noise and the weld metal comes across in large, irregular blobs.

Welding Position The electrodes dealt with in this manual can be used in most positions, i.e. they are suitable for welding in flat, horizontal, vertical and overhead positions. Numerous applications call for welds to be made in positions intermediate between these Arc Welding Practice The techniques used for arc welding are almost identical regardless of what types of metals are being joined.
