8. CAUTION 8.1 Working Environment 1) Welding should be carried out in dry environment with humidity of 90% or less. 2) The working environment temperature should be between -10℃ and 40℃. 3) Avoid welding in the open air unless sheltered from sunlight and rain. Keep welder dry. 4) Avoid welding in dusty area or environment with corrosive chemical gas. -

9. BASIC KNOWLEDGE OF WELDING 9.1 Basic knowledge of MMA Manual metal arc welding (MMA) is an arc welding by manually operating electrode. MMA requires simple equipment and is a convenient, flexible and adaptive welding processing type. MMA is applied to various metal materials with thickness more than 2mm. - Page 16 c) Slag hammer (peen hammer): for the use of removing slag crust on the surface of weld joint. d) Wire brush: for the use of removing dirt and rust at the joints of the workpiece before welding, as well as cleaning the surface of weld joint and the spatter after welding.
- Page 17 Fig. 10 Arc ignition modes 4) Tack weld For fixing the relative positions of the two pieces of weldment and welding conveniently, 30~40mm short weld joints are welded every certain distance in order to fix the relative positions of the workpiece during welding assembly.
- Page 18 3-transversely swing Fig.11 Three basic movement directions of electrode Fig.12 Angles of electrode in flat welding 6) Arc extinguishing Arc extinguishing is unavoidable during welding. Poor arc extinguishing may bring shallow weld crater and poor density and strength of weld metal by which cracks, air holes, slag inclusion and shortage the like are easy to be produced.
- Page 19 GMAW can be applied to the welding of most metals and alloys, and it is ideal for welding carbon steel, low alloy steel, stainless steel, aluminum, aluminum alloy, copper, copper alloy and magnesium alloys. For metal with high melting point such as high strength steel and high strength aluminum alloy, some ...
- Page 20 c) Welding torch: The welding torch for GMAW can be classified into semi-automatic torch and automatic torch, and the former can be classified into air-cooled torch and water-cooled torch according to different cooling methods. 9.2.3 Basic Operation of GMAW a) Preweld cleaning, equipment checks and labor protection Preweld cleaning Chemical cleaning: Chemical cleaning methods vary with the materials.
- Page 21 Mechanical cleaning: Mechanical cleaning includes sanding, scraping and sand blasting, and it is used to clean oxidation film on the metal surface. Equipment check Firstly, check if there are obvious damage marks on the exterior of the welding machine, and if there is any lack or damage of any components of the welding machine.
- Page 22 The effect on the weld bead shaping caused by the angle of welding wire is shown in the above figure. When welding wire changes to backward position from vertical position with other conditions fixed, the penetration will increase, the weld bead will narrow, the weld reinforcement will increase, and arc will be stable with little spatter.
- Page 23 e) Arc extinguishing Do not extinguish arc immediately when ending welding. Otherwise, crater will be left and defects such as cracks and air holes are easy to be produced. Keep the torch staying a little while at the crater when extinguishing arc, and raise the torch slowly after the crater is filled, so that the molten pool can be well protected before it is solidified.

c) Vertical position welding There are two modes for the vertical position welding of GMAW, namely upward welding in the vertical position and downward welding in the vertical position. Due to the gravitation effect, the melting metal may drop down easily in upward welding in the vertical position. -

equipment (including that between the connections and that between the connection and the enclosure). Only when there are no abnormal phenomena anymore, can the machine be used. 5) Check periodically whether the insulation cover of all cables is in good condition. If there is any dilapidation, rewrap it or replace it. - Page 26 There is output current when pushing the torch trigger to feed gas, but the The wire feeder is clogged. Unclog it. wire feeder does not work. The wire feeder fails. Repair it. The control PCB or wire feeding power Replace it. PCB inside the machine fails.
