Set the tightness of the wire brake
Tightness only need to ensure that the wire will not loose, but not too tight, otherwise it will cause the welding wire to drag and drop. To correct the setting, first the tightness to the minimum, and then put on the welding wire, let it through the drive roller, if in addition to welding wire roller is moving, and other parts have stopped, that is not tight enough. 

Be careful when handling, because too tight will cause excessive force on the wire. In addition, do not strain the last few laps of the wire when it is out of use; it is usually difficult to loosen because the wire is too hard. Harbin Dong Xing aluminum co., ltd could provide you with 5083 aluminum plate on sale.

Set the drive roller tightness
This is probably the most important step in the entire setup program. Experts recommend that the wire should be placed at a slight angle 1 inches from the surface of the insulating material. Then, set the roller tightness at almost the minimum. Press the switch on the torch to observe its operation it should slide when the wire touches the surface of the insulating material. From that point, tighten the tightness until the wire stops sliding. Again, be careful, too tight will lead to fracture of the wire. This means that the wire stays in the welding gun, welding wire and drive roller are still in rotation, the final result is out after fracture or roller wire, lead wire back backlog of chaos, including guide liner, liner welding etc.. 

Remember, press the switch of the torch when you set the tightness of the wheel according to the above. The wire sent is hot, so always wear a good quality welding glove.  Harbin Dong Xing aluminum co., ltd is a competent and reliable Aluminum plate  manufacturer china.
Ensure good power connections
In the first step, the welding fixture shall be securely clamped in the areas where the weld is not painted and contaminated. To clean the workpiece, remove all grease with a grease removing solvent. Before welding, make sure the surface of the workpiece is dry. At the same time, do not solder in the vicinity of combustible material, such as solvents or paint containers. The second step is to clean the surface oxide of aluminum with a clean stainless steel wire brush.

Positioning is very important
When welding, try to keep the straight line of the welding torch cable to reduce the feeding limit of the soft aluminum wire to the maximum extent. The bending of the welding torch cable leads to the tying of the welding wire, resulting in poor wire feed.
