The welding machine is useful to every handyman. It is used for many products. For its acquisition does not necessarily apply to the pro shop. The unit of resistance welding can be done independently of the old microwave ovenApplying the necessary knowledge and a little imagination.

Spot welding apparatus stands out for its performance at low consumption of time. It is used to connect two metal parts. At the time of heating using the electricity generated clutch surfaces. This ensures the bonding strength. The device reaches a small size and is operated manually.
expendable material
Microwave - useful kitchen appliance. In today's world it is present in almost every home. Special experts have found a use not only in the culinary field.
You can collect a large number of useful devices, including the device spot welding of the components of the furnace.
Required for the manufacture of:
- transformer of a microwave oven;
- tape winding;
- electrodes;
- wire for tying;
- Control components (lever and switch).
After preparation of consumables can start the installation and build process.
stages of work
The working process takes a minimum of time and knowledge. Following the established instructions and in compliance with safety regulations, to collect from an old microwave welding machine can be anyone.
The first step is transformer extraction. Rear body needs to be removed, being careful. The transformer should be carefully removed without applying during heavy or sharp objects. The use of additional materials inflict serious damage. Such actions provoke the reasons for its failure.
For the manufacture of spot welding machine It recommended the use of transformers of the more powerful models of microwave ovens. They are distinguished by improved functionality and are more reliable in operation.
after extraction It removed one of the him windings - secondary. When carrying out demolition work, you can use tools to help facilitate the work (most importantly - accuracy). Upon detection of restrictive shunts also recommend their removal. The primary winding is left due to the use of a denser wire and fewer turns.
After removal of the new reel is mounted. It is better to use a wire diameter of not less than 1 cm. After this modernization transformer is again ready for use. He will serve as the basis for the welder.
The next step is electrode mounting. when selecting experts recommend to pay attention to the corresponding electrode diameter to the diameter of the connecting wires. For this small copper rods are ideal.
It is recommended to use the minimum length of the electrodes. This will provide a stable high power device. When large diameter component can be used special tips.
For installation and the tip electrode are connected using bolts or nuts. As a connecting material is better to use copper. Among others they are allocated the minimum electrical resistance performance. This will ensure no loss of power.
Fastening controls It will not take long. These include lever and switch.
The lever controls a power flow between the electrodes and the workpiece to be repaired. The base of the lever is mounted in the primary winding circuit, the movable electrode. It is not recommended to connect to the secondary winding. This will trigger a significant disruption of electricity or cause the circuit.
lever length is chosen depending on personal preference and convenience, which are necessary in the process.
The switch is engaged in supply of electricity from the base to the welding electrodes. It can also cling to the primary winding.
Switch recommended positioned directly above the lever. This will provide added convenience when working with a welding machine.
Exploitation
Spot welding apparatus, made of components from a microwave oven, is not only simple assembly. The main advantage is the favorable price policy: the cost of the component parts is minimal. In most cases, they do not exist at all, because all the necessary components and are already in a personal toolbox. Ready machine on the shop window do not always attract the attention of buyers because of the rather high price. Assembly machine spot welding of microwaves - effective solution.
It is desirable that the device was equipped with a fan. If this is not possible, when using periodically must be turned off to cool the parts.
conclusion
Spot cooking apparatus is used for a wide range of services. Collect the device can independently of the parts of the old faulty or microwave oven, saving a considerable amount of cash. The availability of personal welding machine and save more private time, because there is no need to apply to the specialized centers. With proper workflow and rules of operation the unit will long serve its manufacturer.
The wire diameter of 1 cm, which recommends that the author of the article has a cross section of 0.9 square meters. or 90 sq cm. mm. Author, how are you going to stick to it? The number of turns - at the reader's discretion. Create, invent, try! If you could put the article "-1", I'd bet.
