WARNING The device and packaging material are not toys! Children must not be allowed to play with the machine and its accessories. Plastic parts and packaging are choking risks for children. • Open the packaging and remove the welder carefully. •... -
Page 7: Machine Care / Safety Instructions
MACHINE CARE / SAFETY Keep the welding cables, earth clamp and electrode holder in good condition. Failure to do this can result in poor welding quality, which could be dangerous in structural situations. Prior to use, check for breakage of parts and any other conditions that may affect operation of the welder. Any part of the welder that is damaged should be carefully checked to determine whether it will perform its intended function whilst being safe for the operator. -
Page 8: Work Area Safety
WORK AREA Ensure a clear, well lit work area with unrestricted movement for the operator. The work area should be well ventilated, as welding emits fumes which can be dangerous. Always maintain easy access to the ON/OFF switch of the welder, and the electrical mains supply. Do not expose the welder to rain and do not operate in damp or wet locations Where welding must be undertaken in environments with increased risk of electric shock, confined spaces or in the presence of flammable or explosive materials, it is important that the environment be evaluated in advance... -
Page 9: Maintenance & Disposal
MAINTENANCE WARNING Before starting any cleaning, or maintenance procedures on the welding machine, make sure that it is switched OFF and disconnected from the mains supply. There are no user serviceable parts inside the welder. Refer to a qualified service personnel if any internal maintenance is required. -

A welder must be able to strike and establish the correct arc easily and quickly. The scratching method is easier for beginners.

TIPS • Keep the welding current as low as possible for the job at hand to maintain the best duty cycle from your welding machine, prevent the flux from burning and make slag removal easier. • To break the circuit withdraw the electrode from the work piece. Be careful with the end of the electrode, as it will be HOT. - Page 14 MANUAL METAL ARC PROCESS (MMA WELDING) When an arc is struck between the metal rod (electrode) and the workpiece, both the rod and workpiece surface melt to form a weld pool. Simultaneous melting of the flux coating on the rod will form gas and slag which protects the weld pool from the surrounding atmosphere.

TUNGSTEN SELECTION / PREPARATION & GRINDING ELECTRODES Electrodes for DC welding are normally pure tungsten with 1 to 4% thoria to improve arc ignition. Alternative additives are lanthanum oxide and cerium oxide which are claimed to give superior performance (arc starting and lower electrode consumption). - Page 20 TIG WELDING - CONTINUED This risk can be minimised using the ‘lift arc’ technique where the short-circuit is formed at a very low current level. The most common way of starting the TIG arc is to use HF (High Frequency). HF consists of FLUX COATING high voltage sparks of several thousand volts which last for a few microseconds.
