WELDSKILL 170 HF INVERTER SECTION 1: ARC WELDING SAFETY INSTRUCTIONS AND WARNINGS ! WARNING PROTECT YOURSELF AND OTHERS FROM POSSIBLE SERIOUS INJURY OR DEATH. KEEP CHILDREN AWAY. PACEMAKER WEARERS KEEP AWAY UNTIL CONSULTING YOUR DOCTOR. DO NOT LOSE THESE INSTRUCTIONS. READ OPERATING/INSTRUCTION MANUAL BEFORE INSTALLING, OPERATING OR SERVICING THIS EQUIPMENT.
WELDSKILL 170 HF INVERTER 2. Wear approved safety glasses. Side shields recommended. WARNING 3. Use protective screens or barriers to protect others from flash and glare; warn others not to watch the arc. ARC RAYS can burn eyes and skin; NOISE can damage hearing. 4. Wear protective clothing made from durable, flame-resistant material (wool and leather) and foot protection. Arc rays from the welding process produce intense heat and strong ultraviolet rays that can burn eyes and skin.
WELDSKILL 170 HF INVERTER WARNING FUMES AND GASES can be hazardous to your health. Welding produces fumes and gases. Breathing these fumes and gases can be hazardous to your health. 1. Keep your head out of the fumes. Do not breath the fumes. 2. If inside, ventilate the area and/or use exhaust at the arc to remove welding fumes and gases. 3. If ventilation is poor, use an approved air-supplied respirator. 4.
WELDSKILL 170 HF INVERTER 4. Never allow a welding electrode to touch any cylinder. 5. Use only correct shielding gas cylinders, regulators, hoses, and fittings designed for the specific application; maintain them and associated parts in good condition. 6. Turn face away from valve outlet when opening cylinder valve. 7. Keep protective cap in place over valve except when cylinder is in use or connected for use. 8.
WELDSKILL 170 HF INVERTER To reduce magnetic fields in the workplace, use the following procedures. WARNING STEAM AND PRESSURIZED HOT COOLANT can burn face, eyes, and skin. The coolant in the radiator can be very hot and under pressure. 1. Keep cables close together by twisting or taping them. 2. Arrange cables to one side and away from the operator. 3. Do not coil or drape cable around the body. 4. Keep welding power source and cables as far away from body as practical. 1.

WELDSKILL 170 HF INVERTER SECTION 4: OPERATION 4.01 Overview Conventional operating procedures apply when using the Welding Power Source, i.e. connect work lead directly to workpiece and electrode lead is used to hold electrode. The welding current range values should be used as a guide only.
WELDSKILL 170 HF INVERTER 4.03 Front Panel Functions Refer to Figure 4-1 on the previous page. A. Power ON Indicator The Power ON Indicator illuminates when the ON/OFF switch is in the ON position and the correct mains voltage is present. B. Over Heat Indicator The welding power source is protected by a self resetting thermostat. The indicator will illuminate if the duty cycle of the power source has been exceeded.
WELDSKILL 170 HF INVERTER 4.04 Arc Welding Electrodes 4.05 Types of Electrodes Metal arc welding electrodes consist of a core wire surrounded by a flux coating. The flux coating is applied to the core wire by an extrusion process. Arc Welding electrodes are classified into a number of groups depending on their applications. There are a great number of electrodes used for specialised industrial purposes which are not of particular interest for everyday general work.

WELDSKILL 170 HF INVERTER 4.07 Size of Electrode The electrode size is determined by the thickness of metals being joined and can also be governed by the type of welding machine available. Small welding machines will only provide sufficient current (amperage) to run the smaller size electrodes. For thin sections, it is necessary to use smaller electrodes otherwise the arc may burn holes through the job. A little practice will soon establish the most suitable electrode for a given application. 4.
WELDSKILL 170 HF INVERTER 4.12 Welding Position The electrodes dealt with in this publication 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. Some of the common types of welds are shown in Figures 4-2 through 4-9.
WELDSKILL 170 HF INVERTER 4.13 Joint Preparations In many cases, it will be possible to weld steel sections without any special preparation. For heavier sections and for repair work on castings, etc., it will be necessary to cut or grind an angle between the pieces being joined to ensure proper penetration of the weld metal and to produce sound joints. In general, surfaces being welded should be clean and free of rust, scale, dirt, grease, etc. Slag should be removed from oxy-cut surfaces.
WELDSKILL 170 HF INVERTER 4.14 Arc Welding Technique A Word to Beginners 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 mild steel plate about 6.0mm thick and a 3.2mm electrode. Clean any paint, loose scale or grease off the plate and set it firmly on the work bench so that welding can be carried out in the downhand position.
WELDSKILL 170 HF INVERTER 4.19 Making Welded Joints Having attained some skill in the handling of an electrode, you will be ready to go on to make up welded joints. A. Butt Welds Set up two plates with their edges parallel, as shown in Figure 4-12, allowing 1.6mm to 2.4mm gap between them and tack weld at both ends. This is to prevent contraction stresses from the cooling weld metal pulling the plates out of alignment. Plates thicker than 6.
WELDSKILL 170 HF INVERTER C. Vertical Welds 1. Vertical Up Tack weld a three feet length of angle iron to your work bench in an upright position. Use a 3.2mm Ferrocraft 21 electrode and set the current at 100 amps. Make yourself comfortable on a seat in front of the job and strike the arc in the corner of the fillet. The electrode needs to be about 10° from the horizontal to enable a good bead to be deposited. Refer Figure 4-16. Use a short arc, and do not attempt to weave on the first run.
WELDSKILL 170 HF INVERTER 4.20 Distortion Distortion in some degree is present in all forms of welding. In many cases it is so small that it is barely perceptible, but in other cases allowance has to be made before welding commences for the distortion that will subsequently occur. The study of distortion is so complex that only a brief outline can be attempted hear.
WELDSKILL 170 HF INVERTER D. Presetting It is possible in some cases to tell from past experience or to find by trial and error (or less frequently, to calculate) how much distortion will take place in a given welded structure. By correct presetting of the components to be welded, constructional stresses can be made to pull the parts into correct alignment. A simple example is shown in Figure 4-22.
