Second. the welding

1, adjust the operation car to the welding position, if it is reverse driving to the welding position, to cross the welding arc point, and then drive in the welding direction, in order to eliminate the mechanical gap, to avoid the appearance of welding tumor, arc point in the back of the arc pit, in order to avoid welding tumor or lack of meat.

 

2, set the welding point, point moving "wire feed", "wire back" so that the welding wire gently contact the steel plate, using short circuit contact arc.

 

3. Select the "welding" position of the walking switch.

 

4, adjust the welding current, welding voltage (voltage slightly larger, current slightly smaller), welding speed.

 

5, Select the driving direction, press the corresponding "left" or "right".

 

6. Open the flux feeding valve, cover the flux in the welding area, move the flux control to open about "recovery", the recovery device works

 

7. Press the "Start" button of welding to start arc welding and adjust the welding current and welding voltage knob to the required value of welding specification.

 

8. Observe the position of welding bead and the forming of welding bead, adjust the welding speed and the upper and lower height of welding torch to obtain the best welding effect.

 

9, during the welding process, pay attention to observe the welding bead, pay attention to the obstacles ahead, welding cable to follow the situation, etc., in order to avoid driving obstacles.

 

10. Avoid contact with welding gun and wire feeder by hand and metal tools in welding to prevent short road accidents.
