1. Overview

CO2/MAG/MIG welding automatic trolleys are widely used in ships, bridges,locomotives, steel structures, petrochemical industries and other industries.They are suitable for welding a variety of welded structures, such as: weldingof stiffener plates, ribs, cross parts, box beams Welding, etc. Its mainadvantages are:

1.1 Reduce labor intensity and improve the working environment;

1.2 Improve work efficiency, which is 1.5 times that of manual welding;

1.3 Avoid poor weld quality caused by human factors. Generally, thedefect rate of manual operation is about 20%, and the use of automatic weldingtrolleys does not result in the resulting weld defect rate;

Therefore, its comprehensive benefit is nearly 200% higher than that ofmanual welding;

1.4 High degree of automation to ensure the stability of welding quality;

1.5 Does not require very skilled technical workers;

The soft rail welding trolley is the preferred choice for pipe weldingand curved surface welding, and can travel automatically according to the arcof the track.

2. Features

1) It can realizewelding in various positions such as vertical welding, horizontal welding andhorizontal welding and Circular welding (workpiece diameter ≥1400mm) .

2) With swingfunction. Various swing parameters such as swing mode, swing amplitude, swingspeed, swing center position and left and right stay time can be adjusted.

3) The running speedof the trolley is displayed digitally.

4) In order toprevent undercut and insufficient welding during weaving welding, the left andright weaving stop time adjustment function is set up.

5) When weldingstops, the welding gun will automatically return to the center of the weldbead.

6) With automatic arcclosing function.

7) With fast returnfunction.

8) Standardconfiguration provides 1.8m long track.

3. Outline drawing anddescription of main components

Body: welding gunfixture, swing head, clutch device, welding gun, fine-tuning slider, controlbox and other components

1) Driving part: Itis composed of the device that drives the trolley, the track, the bevel gear,the traveling device, the sprocket, the clutch, and the traveling motor;

2) Fine-tuningslider: It is a device for adjusting the position of the welding gun, which canbe fine-tuned up and down, left and right during welding.

3) Welding gunfixture: It is a device to fix the welding torch. It is convenient for thedisassembly of the welding torch during maintenance and adjustment, and theangle of the welding torch can be adjusted.

4) Clutch device andclutch: easy to install the trolley and move

5) Control box: allmovements of the trolley can be adjusted, and both welding torches arecontrolled by this control box.

4 Control paneldescription

(1) "WELDING ON /WELDING OFF" switch: when the"WELDING ON" position is selected, it will enter the weldingpreparation state, and press the "start" switch to weld; when the"WELDING OFF" position is selected, press the "start"switch, the cart will only move but No welding is performed.

(2) "START" switch: Turn on the switch and thetrolley starts to walk, if the "WELDING ON /WELDING OFF" selectorswitch is set to the "WELDING ON" position, then welding will start;if the "WELDING ON /WELDING OFF" selector switch is set at this timeIn the "WELDING OFF" position, only the trolley is running butwelding is not performed.

(3) "STOP" switch: If you press the stop switchwhile the car is moving, the car will stop all actions.

(4) Walking direction selection switch: You can choose L-Moveor R-Move to walk.

(5) Speed: The speed value is digitally displayed, themaximum walking speed is 1040mm/min, and the digital display value is 999.

(6) Swing speed adjustment knob: rotate clockwise to increasethe swing speed, the maximum value is 1520mm/min. It is expressed in scale, andthe maximum scale is 10.

(7) Swing frequency adjustment knob: Turn clockwise toincrease the swing frequency, and the maximum value is 20mm. It is expressed inscale, and the maximum scale is 10.

(8) Stop time adjustment knob: the adjustment range is 0~2S,increasing clockwise.

(9) Right stop time adjustment knob: the range is 0~2S,increasing clockwise.

(10) Center movement adjustment knob: when rotating clockwise,the center will move to the right, when rotating counterclockwise, the centerwill move to the left, and the maximum range of movement is ±5mm. Expressed byscale value, the maximum scale value is 5.

(11) Swing mode selection knob: Use this knob to select theswing mode. There are five swing modes for the trolley. Except for the firstone which is non-swing mode, the rest are as follows:

6.Installation method

(1) Installationconditions

a. The necessarytools for welding are welding power source and wire feeder device;

b. Welding powersupply for walking and control (AC 220V);

c. CO2 gas tank forwelding;

d. Straight weldinggun for CO2 automatic welding;

e. Basic tools forother necessary operations;

(2) System connectionmethod

a. Install thetrack. The installation of the track must ensure that the welding direction ofthe trolley is parallel to the welding seam;

b. Install thetrolley, and use the installation handle to clamp the track wheel of thetrolley on the track;

c. Install thewelding wire on the wire feeder and pull it to the end of the welding gun;

d. The welding gunport is connected to the wire feeder;

e. Connect one sideof the trolley's power cable to the 3P socket of the trolley, and connect theother side to the AC 220 power supply.
