Page 7 Personal Protection 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. Arc rays can injure your eyes and burn your skin. The welding arc produces very bright ultraviolet and infrared light.
Page 8 Electric Shock WARNING: ELECTRIC SHOCK CAN KILL! • A person qualified in First Aid techniques should always be present in the working area; If a person is found unconscious and electric shock is suspected, do not touch the person if she or he is in contact with cable or electric wires.
Page 9 Protective Welding Gases Shielding Gas Cylinders contain gas under high pressure. If damaged, a cylinder can explode. Treat them carefully. • Arc welders use only inert or non-flammable gases for welding arc protection. It is important to choose the appropriate gas for the type of welding being performed. •...
Page 10 • Do not squash the supply cable with other machines. It could be damaged and cause electric shock. • Keep the supply cable away from heat sources, oils, solvents or sharp edges. • In case you are using an extension cord, try to keep it straight, and untangled to avoid overheating.
Page 11: Assembly And Major Components
Assembly Handle and Wheels Assembly (FIG.2) • Unpack the welder. • Screw the two casters (D) to the machine. • Insert the axle (A) through the holes at the rear of the welder and slide a wheel (B) on to each end followed by the retaining washers (C).
Page 12 Shielding Gas Guide Metal NOTE Mild Steel Argon + CO2 Argon controls spatter Argon + CO2 + Oxygen Oxygen improves arc stability Aluminium Argon Arc stability, good fusion and minimum spatter. Higher heat input suitable for heavy sections. Argon + Helium Minimum porosity.
Page 13 • Loosen and lower the plastic knob (A) (Fig.5). Release the upper roll (B) of the feeder. Extract the wire from the torch liner. • When the wire is disconnected, grasp it with pliers so that it cannot exit from the spool. If necessary, straighten it before inserting it in the wire input guide (C).
Page 14 How to Choose the Wire Liner for Direct and Euro Connection Torches • There are basically 2 types of wire liners: Steel wire liners and Teflon wire liners. • Steel wire liners can be coated or not coated. Coated wire liners are used for air cooled torches.
Page 15 14. Flip the quick release drive tensioner back into position on the drive tensioner arm. 15. Tighten (turn clockwise) the drive tension adjusting knob until the tension roller is applying enough force on the wire to prevent it from slipping out of the drive assembly. 16.
Page 16: Front Panel Operation
Front Panel Operation With welders in the digital series, thanks to a special electronic card it is possible to adjust externally the main welding parameters. The main purpose of these units is to make adjustment of these parameters very easy. The microprocessor control handles the functions of the p.c.board that are viewed by means of LED’s while a digital display shows the parameters set and welding current.
Page 17: General Operating Instructions
Welding Preparation • Connect the ground cable to the proper female outlet on the bottom right-hand corner of the welder (on some models the ground cable is already connected). Attach the ground clamp to the bare metal to be welded, making sure of good contact; •...
Page 18 The display can view numbers from 1 to 99 (1 being the minimum value and 99 the maximum value). The display shows the real welding current and the value of the parameter you selected and adjusted during the regulation phase. After welding the display will view the welding current value for a maximum of 5 seconds.
Page 19 Welding Hints and Maintenance • Always weld clean, dry and well prepared material. • Hold gun at a 45° angle to the workpiece with nozzle about 1/2” from the surface. • Move the gun smoothly and steadily as you weld. •...
