Spot Welder Advantages Limitations & Applications:

Advantages:

* The procedure involves smaller amount maintenance money.
* Ability of the worker does not influence the quality of spot welds obtained by this procedure.
* The process is usually free from burn and splash.

Limitations:

* To achieve small cost of building, the weld manufacture cost is not very high.
* The procedure proves uneconomical as compared to resistance spot welding where the latter are able to be simply employed.

Applications:

The use of physically operated arc spot welding gun is an ordinary thing in a variety of industries. Arc spot welding is particularly applicable for situations where resistance spots welding wants high pressure, high currents, does not have simple access and therefore fails to weld.

Arc spot welding torch be able to also be working to make holes in plates up to 3 mm broad or consequently. After the arc has impinged on the plate for a exact time, high force inert gas blows away the molten metal leaving a hole in the plate. Additional applications of, the process are in:

1. Automobile manufacturing.
2. Manufacture of sheet metal goods.
3. Assemble sheet metal to steel structures.
4. Manufacture of pulleys.
5. Joining killed carbon steel, low alloy steel, high alloy steel, titanium, etc.

Arc-Welders

All arc welding and cutting cables shall be of the completely insulated, flexible type, capable of handling the maximum current requirements of the work in progress, taking into account the duty cycle under which the Arc welder or cutters is working.

Any current-carrying parts passing through the portion of the holder which the Arc welder or cutter grips in his hand, and the outer surfaces of the jaws of the holder, shall be fully insulated against the maximum voltage encountered to ground.

Only cable free from repair or splices for a minimum distance of 10 feet from the cable end to which the electrode holder is connected shall be used, except that cables with standard insulated connectors or with splices whose insulating quality is equal to that of the cable are permitted.
