Page 4: Safety
1. Safety Welding and cutting equipment can be dangerous to both the operator and people in or near the surrounding working area, if the equipment is not correctly operated. Equipment must only be used under the strict and comprehensive observance of all relevant safety regulations. Read and understand this instruction manual carefully before the installation and operation of this equipment. - Page 5 Never touch live electrical parts. Wear dry, hole-free gloves and clothes to insulate your body. Be sure to install the equipment correctly and ground the work or metal to be welded to a good electrical (earth) ground according to the operation manual. ...
- Page 6 Read and understand the manufacturer’s instructions for this equipment and the consumables to be used, including the material safety data sheet and follow your employer’s safety practices. ARC RAYS: Harmful to people’s eyes and skin. Arc rays from the welding process produce intense visible and invisible ultraviolet and infrared rays that can burn eyes and skin.
- Page 7 WELDING SPARKS can cause fire or explosion. Welding on closed containers, such as tanks, drums, or pipes, can cause them to explode. Flying sparks from the welding arc, hot work piece, and hot equipment can cause fires and burns. Accidental contact of electrode to metal objects can cause sparks, explosion, overheating, or fire. Check and be sure the area is safe before doing any welding.
- Page 8 Never allow the electrode, electrode holder or any other electrically “hot” parts to touch a gas cylinder. Keep your head and face away from the cylinder valve outlet when opening the cylinder valve. Valve protection caps should always be in place and hand tight except when the cylinder is in use or connected for use.

on and at the same time the output current will be cut off. It can self-protect, prolong the usefull life, greatly improved the reliability and practicality of the welding machine. ARC series of welding machines can also realize TIG operation. While MMA operation, if the electrode touches workpiece over two seconds, the welding current will drop to the minimum current automatically to protect the electrode. -
Page 16: Working Principal
• 2.5. Working Principle The working principle of ARC series of welding machines is shown in the following figure. Single-phase 110V/220V line frequency AC is rectified into DC, then is converted to medium frequency AC by inverter device (IGBT), after reducing voltage by medium transformer (the main transformer) and rectified by medium frequency rectifier (fast recovery diode), and is outputted by inductance filtering. -

(3) Set the welding current relevant to the electrode type and size being used as recommended by the electrode manufacturer. (4) Place the electrode into the electrode holder and clamp tight. (5) Strike the electrode against the work piece to create and arc and hold the electrode steady to maintain the arc. - Page 20 The arc is initiated by momentarily touching the electrode to the base metal. The heat of the arc melts the surface of the base metal to form a molten pool at the end of the electrode. The melted electrode metal is transferred across the arc into the molten pool and becomes the deposited weld metal.

• 3.2.4. MMA Welding Fundamentals Electrode Selection As a general rule, the selection of an electrode is straight forward, in that it is only a matter of selecting an electrode of similar composition to the parent metal. However, for some metals there is a choice of several electrodes, each of which has particular properties to suit specific classes of work. -

poor quality welds. General rule of thumb for down hand welding is to have an arc length no greater than the diameter of the core wire. Electrode Angle The angle that the electrode makes with the work is important to ensure a smooth, even transfer of metal. - Page 23 Increase the amperage or choose a Insufficient heat input larger electrode Remove moisture and materials like Work piece dirty, contaminated paint, grease, oil, and dirt, including or moisture mill scale from base metal Weld sits on top, lack of fusion Use the correct welding technique or Poor welding technique seek assistance for the correct...
