Operation Specifications for

Pneumatic Spot Welding Gun

There are Series C and X pneumatic spot welding gun with integrated, separated or pipe type of construction and over several hundreds of models available. Before the delivery, each one of the products is subjected to the 100% strict inspection. With reliable product quality and credit, we guarantee to carry out our policy of “three guarantees for repair, replacement or compensation of faulty products”, support the auxiliary parts, and supply the products.

We are willing to design and manufacture various kinds of special welding guns upon users’ requirements. We sincerely offer you our on time service no matter how many are the quantity. Generally the date of delivery is three months but if it is urgent , it can be determined by discussion. We still offer assistance to installation and debugging upon requirements.

1,Application & Characteristics

Combining with the specific conditions of our domestic users, the Series C and X pneumatic spot welding guns are the water-cooled pneumatic spot welding guns developed by ourselves. They are mainly used to overlap and spot-weld low carbon steel sheet stampings. For the mass flow-line production, they are the ideal welding tools for promoting welding quality and improving theworkingintensity, so they are widely applied to the fields such as automobile body welding, enclosure manufacturing of washing machine and refrigerator, etc.

Being reasonable in design, good inperformance, compact in construction, portable and endurable, they are such designed that the pneumatic double-stroke and the end flexible coupling construction are employed so they are still provided with the advantages of reliable centralizing alignment of electrodes, easy adjustment, convenient operation, wide scope of application, long service life, etc.

The cap-shaped electrodes are easy for replacement and save 2/3 materials of electrodes compared with the others, with the arm made by the high strength copper alloy pipe-buried cast technology. The arm of gun having high rigidity and good coolingperformancegreatly prolongs the service life.

They are specially suitable for the introduced and domestic double gas circuits suspension spot welder or constant-current control box.

2,Installation Instruction and Maintenance

(1).Installation

1.According to the actual production demands, users can select by themselves the national Portable Spot Welders and controllers or those imported from abroad, and can be used with the products in our company.

2.Connect the corresponding water pipe, gas pipe and cable according to the schematic diagram.(See the figure)

3.Guarantee the unblock of drain-pipe which was connected.

4.The contact surface in the junction of the cable joint and welding gun arm should not be less than 70% of designed value.

(2).Operation

1..Connect the water route and check if the rate of flow is still normal.

2.Connect the gas source and check if the air pressure is not less than 0.44Mpa.

3.Start the weld button and check if the operation of welding gun is still normal and also the positions of the upper and lower electrodes are well placed. If finding the misplacement, it should be adjusted then put into operation.

4.Before welding, the time of “compression” ,”welding” ,”holding” and “rest” should be adjusted according to the requirements of technology, then put into the trail-welding after the greasy dirt and rust on the surface of weldment is cleaned.

5.Check the quality of welding spot: After the two spot welding is stripped, the stitching should be kept on a board, the diameter of stitching is about 80% of that of the electrode end socket, which shows the good quality of weld spot, then it can be put into welding. Otherwise, the specifications of the technology should be adjusted once again.

(3).Maintenance

1.The surface of electrode head should be assured no existence of other sticking , and the overall of electrode head should be often repaired and maintained. If finding the serious wear of electrode head or pit on the end, it should be replaced immediately.

2.Check the gas circuit and the system of water route regularly. No blocking and leakage is allowed.

3.Check the cables for water regularly, and it should be replaced in time if finding the break-off of partial conductor.

4.During the welding, avoid the contact of welding gun and work piece to prevent the electrode or work piece from the short circuit caused by two stage electrode.

5.Discharge the cooling water completely after stop using.

3,After-sale service

(1).The pneumatic welding guns made by our factory are guaranteed for half year after leave the factory. Our factory is responsible for the free replacement if the problems of quality occur within the period of guarantee. For the damages caused by users because of the wrong application, only the cost fee is required.

(Note: The quick-wear parts of electrode head, electrode connecting pole and axle sleeve etc. are not in the range of the guarantee. But our factory assures to providethe accessoriesin time.)

(2).The specialized technicians in our factory are in charge of the after-sale service. They will get there within three days after receiving the advice of users in theprovinceor city while a week for other provinces or cities.

(3).All theaccessoriesare assured to supply if the products are made by ourfactory.After receiving the users’ advising bill for the requiredaccessories,our sales departments will post them to your units within five days.
