How to use a wire feed welderWire Feed welder is a welding machine used in Metal Inert Gas (MIG) Welding and Flux Cored Arc Welding(FCAW). It Is a compact machine that uses a thin wire consumable electrode, fed through an electric gun, to produce an arc of electricity and weld the working metal. In MIG welding a layer of shielding gas is also sprayed through the gun to protect the metal surface from air contamination. The welder just has to start the gun, produce a steady electric arc and then move the gun down the joint. The wire feeds out of the electric gun continuously until the welder pulls the trigger.Wire Feed welder is not much different from stick welding in terms of basic tips and techniques. Just like stick welding, wire feel welder also requires a comfortable position, steady hand,the appropriate angle of the electrode and gun, gas and electric supply settings and the wire feed speed. These setting wary from metal to metal and with practice you can learn the right setting for all kinds of metals like stainless steel, carbon steel, aluminum and nickel alloys.There are a few basic settings of best miller MIG welder that are Wire feed welders and must be checked before using a wire feed welder.Wire Feed Welders ---- Voltage and Amperage:The voltage setting of wire feed welders varies from metal to metal and depend upon metal thickness, wire diameter, welding position and type of joint. You can refer to manual charts for suggested settings for each kind of metal.Wire Feed Welders ---- Electrode Stick Out:Electrode stick out is the length of wire that extends out from the tip of the gun. For MIG welding this length is supposed to be inch while for FCAW this length is suggested to be around inch.Wire Feed Welders --- Wire Feed Speed:The wire feed speed is the most important aspect of wire feed welders. If you want a clean,good quality weld you must be very accurate about the wire feed speed. Unfortunately, there is no hard and fast rule for adjusting the wire feed speed. It is a hit and trial method and you must test on scrap metal first to find a good wire feed speed for your respective metal. The wire feed speed is also directly proportional to the power settings of the welder. For high power settings you need to increase the wire feed speed also and vice versa. Generally, for thinner metals a slow wire feed speed is recommended and hence low power supplies.Wire Feed Welders --- Torch Angle and Movement:Torch angle is another important feature of wire feed welders and plays a critical role in getting good quality welds. The torch should be held at an angle of 20 degrees from the metal surface and it should never touch the metal. The distance of the torch from the metal surface must be around 6mm to 10mm. A wire feed welder torch can be moved in a variety of angles and directions, but a zig zag motion of the torch is most recommended. It gives a thorough weld and both sheets, that are to be welded, receive the arc equally.http://topwelders.com/best-miller-tig-welder/
