Congratulations on the purchase of your new 1311"1_ welder. Before attempting to operate this machine, please read this manual thoroughly and follow all instructions carefully. By doing so you wilt help to ensure the safety of both yourself and others around you, and at the same time, you should look forward to long and trouble free service from your I_lll'_J welder. 1.0 Safety 1A.0 Precautions Normes 2.0 Arc Welding 3.0 Thermal 4.0 Electrical 5.
1.0 SAFETY 1.1 GENERAL PRECAUTIONS INSTRUCTIONS Make sure this manual is carefully read and understood operator. by the 1.2 LOCATION Welding processes of any kind can be dangerous not only to the operator but to any person situated near the equipment if safety and operating rules are not strictly observed. These are the main precautionary measures to observe: • Operators should protect their body by wearing closed, non-flammable protective clothing, without pockets or turned up trousers.
1.3 SAFETY INSTRUCTIONS For your safety, before plugging in the welder, closely follow these instructions: • When working in a confined space, the welder must be kept outside the welding area and the ground cable should be fixed to the workplace. Never work in a damp or wet area, in these conditions. • Do not use damaged input or welding cables. • The welding torch should never be pointed at the operator's or another person's body.

D'UTILISATION Si les normes de securite et d'utilisation ne sont pas soi,qneusement respectees, les operations de soudaqe peuvent devenir dan,qereuses non seulement pour I'operateur, mais aussi pour les personnes se trouvant & proximite du lieu ot_ le soudaqe a lieu.
1A.3 INSTRUCTIONS POUR LA S¢:CURIT¢: Pour sauvegarder votre securit6, suivez attentivement ces instructions avant de brancher le gen6rateur & la ligne: • Si le lieu de travail est exigu, I'appareil doit 6tre place en dehors de la zone de soudage et le c&ble de masse doit _tre fixe & la piece en travail. Dans ces conditions, il ne faut pas travailler dans des zones humides ou mouillees. • Ne jamais utiliser des c&bles d'alimentation endommages.
2.0 ARC WELDING - HOW IT WORKS Arc welding is a process by which two pieces of metal are joined together using the heat developed by an electric arc between the workpiece and an electrode (welding material). The electrode is connected to one output side of the same transformer. When the electrode comes into contact with the workpiece an arc is struck. The high temperature of the arc melts the electrode into the joint of the work piece and fusion occurs.
4.0 ELECTRICAL CONNECTION The wires in the input cable of this machine are colored in accordance with the following code: 120V. 230V. Green Ground Green & Yellow Ground White Neutral Blue Live Black Live Brown Live 120 Volts 20Amp grounded plug: Model 80E - 95E - 131E. 230 Volts grounded plug: Model 240TE WARNING: This machine must be grounded. If you intend on using an extension cord make sure the wire cable size is adequate in diameter.
2 The size (diameter)ofweldingrod shouldbe approximately the same as the thicknessof metalto bewelded.An appropriate currentmustbe selectedby turning the large handwheel(itemC) untilthe slidingindicator(item D) inthe top of the machineshows the required amperage setting. With practice you will gain a feel for the correct amperage setting for different welding rod thicknesses. For beginners the table below gives some useful guidelines.

6.0 WELDING TECHNIQUE 1 Plug your welder into the correct socket and switch on using the ON/OFF switch (Item B). NOTE (for models 80E, 95E and Easi Arc 150): If the machine stops at any time and the ON/OFF switch lights, the thermostat has intervened. Wait for a few minutes while the transformer cools down and when the ON/OFF switch goes out again welding can begin. 2 Particularly for beginners, the most difficult aspect of the arc welding process is that of striking an arc.
If the resulting weld looks irregular or messy, or shows signs of porosity or slag contamination, you have almost certainly failed to achieve the correct combination. Do not worry as practice will soon cure this, and the following tips on welding pitfalls should help to improve your technique quite quickly. WARNING: Never look at welding arc, it can seriously damage your eyes. Always use the face shield provided or any proper welding mask.
3 Electrode moved over workpiece too slowly - this causes a very wide and heavy deposit which overlaps at the sides. It is wasteful in terms of both time and electrodes used. 4 Electrode moved over the workpiece too quickly - this causes poor penetration with a "stringy" and incomplete weld deposit. Slag is very difficult to remove. 5 Amperage too low - this causes poor penetration and causes the electrode to stick to the workpiece easily.
7 The perfect weld - with the correct combination of arc length, amperage regulation and inclination of the electrode you will, with practice, produce the perfect weld. This should be regular with uniform ripples and no slag contamination. The arc will make a steady crackling sound. 8.
9.0 WELDER DOESN'T WORK? PROBLEM PROBABLE Power source Thermostatic overload activated due to stops. CAUSE overload. POSSIBLE SOLUTION The thermostatic overload automatically resets when the transformer has cooled (approx. 15 minutes). Power switch light Bad connection on but no weld between ground clamp Clean or wire brush the work surface. current, and workpiece. Unstable arc. Impurities on base metal. Clean with wire brush. Porous weld. Dirty base metal. Clean with wire brush.
