• Wire feeding device for all position automatic welding machine of pipeline

Wire feeder can use 0.8 to 1.6 mm diameter filler wire, the diameter of wire plate can be as high as 300, wide 105mm. When choosing filling wire, remember that the melting point of welding wire is approximately the same as that of welding base material.

Be careful When replacing the filler wire, be sure to check the shape of the wire feed wheel, the wire roller groove, the size, and whether the wire guide tube matches the wire used. It is also necessary to check whether the polarity used is applicable to the filler wire.

The user can adjust the pressure of the feeding wheel on the wire feeding mechanism so as to make the filling wire smoothly and smoothly enter the wire guide tube and the welding torch.

If you need to increase the wire wheel pressure, you can turn the black pressure control knob clockwise.

If you need to reduce the wire feed pressure, you can turn the black pressure adjustment knob counter clockwise.

The adjusting knob is engraved with the pressure regulating range. The greater the pressure applied, the more striking the scale indicated.

For hard carbon steel and stainless steel filler wire, make sure the set pressure is large enough to prevent the filling wire from falling out of the wire feed wheel.

Be careful Too much pressure will lead to deformation and damage of the filler wire, and it will also cause friction or damage to the drive wheel bearing, thus shortening its service life. There are two grooves in different sizes in the drive wheel. The user can open the fastening screw of the driving wheel and the groove needed for the rotation of the rotating driving wheel. The usual groove faces outward.

2. Operation procedure

1) Place welding car on pipe or workpiece and add two lines;

2) Press the drop button on the remote control panel on the operating panel. After the torch is separated from the workpiece 10-15mm (usually 10 times of the wire)

3) Press the buttons on the remote control panel to push up or down;

4) Press the button to swing on the remote control box, look at the weld torch swing width; such as swing swing speed or width is not enough about the timing is not enough, according to the swing speed, swing width on the remote control box, left, right and to adjust

5) The welding current, voltage, and the speed of the welding trolley are adjusted to the numerical value of the process parameters;

6) According to the groove width of the weldment, determine whether to swing (groove width, press the swing button, adjust the swing speed, swing width, left and right timing, narrow groove, adjustable, small swing or non swinging welding);

7) Press the direction of welding, press the box on the positive and reverse, to be welded car rotation, press the welding key;

8) Before welding, there are three steps. First, adjust the swing parameters and the height of the welding torch; second adjust the parameters of the car and walk; third, adjust the current and voltage in welding;

9) In the welding process, notice whether the welding gun is aligned with the welding center. 10) If there is deviation, adjust the welding torch in time;

11)If the torch to the left, press the remote control box to adjust the right; to the right, press the remote control box to adjust the left; [welding car in the opposite direction, the side of the anti regulation]

12) After welding, remove the welding car and clean the weld surface.
