KA-GD Magnetic Pipe Orbital Welding Tractor with Electric and Manual Type

KA-GD Magnetic Pipe Orbital Welding Tractor with Electric and Manual Type

I. Product Overview

    KA-GD is suitable for welding internal and external walls of pipelines. No rails are required and welding can be carried out along the arc surface of the workpiece.

    CO2 automatic welding tractor is widely used in ships, bridges, locomotives, steel structure, petrochemical industry and other industries, suitable for a variety of welding structures, such as: reinforcement plate, rib plate, cross parts of the welding, box beam welding, etc.. Its main advantages are:

1, Reduce labor intensity and improve working environment;

2, To improve the working efficiency, it is 1.5 times of manual welding;

3, Avoid the poor quality of welding seam caused by human factors, the defect rate of manual welding is about 20%, and the automatic welding tractor will not produce welding defect rate because of artificial welding. Therefore, its comprehensive benefit is nearly 200% higher than that of manual welding;

4, High degree of automation to ensure the stability of welding quality;

5, Simple and convenient operation, do not need very skilled technical workers.

II. Product features

1, KA-GD is swing automatic welding device, one welding can get a wider weld.

2, Swing speed, swing range, center position and left and right residence time can be adjusted, suitable for various specifications of the weld.

3, Small size, light weight, easy to install and move, unskilled workers can also carry out welding.

4, Permanent magnet is installed to avoid welding line disconnection during welding.

III. Application Environment

Suitable for pipe welding of various steel structures.


IV. Major Component

Components: welding gun swing device, slider, welding gun handle, control box, control panel and other accessories:
1, Swing device: used to drive the welding gun for pendulum swing welding  

2. Driving part: the driving device of the trolley is composed of four magnetic wheels, helical gears, chains and sprockets  

3, Slider part: used to adjust the position of the welding gun, you can fine-tune the position before and after when welding. 

4, welding gun fixture: welding gun clamping device, it can adjust the Angle of the welding gun.  

5, control box: All movements of the tractor can be adjusted. For details, refer to the operation method of the control panel 

V. Control Panel Introduction


1, Knob for adjusting current and voltage: Turn the knob clockwise to increase the value (The tractor has two power plugs of 3P and 8P, when using 3P plug, the current and voltage adjustment knob is invalid, and then the current and voltage of the wire feeder must be adjusted; Current and voltage control knob is effective when using 8P plug)

2, Selection knob for welding/non-welding: the knob must be in the welding position to weld

3, Point feed: manual wire feed device

4, Walking switch: control the car walking and stopping, if the "welding/non-welding" switch is placed in the "non-welding" position, open the walking switch, the tractor only walking without welding

5, Walking speed adjustment: the adjusting knob of tractor walking speed. It is recommended to adjust the tractor walking speed after turning on the walking switch

6, Choice of walking direction: choose to walk left or right

7, Power switch and indicator light: the indicator light is on after the power is energized

8, Swing control part: it can adjust swing speed, swing range, left and right stay time, center position and swing mode
