Homemade Heavy Duty Automatic Soldring Gun

 

Welcome to Multi Projects in this video I'm gonna make automatic soldring gun. This gun feed soldring wire automatically by pushing button. This 40 watt gun helps you sold any thing in few seconds. 

This auto feed soldring gun consists on DC gear motor to provide continously soldring wire on the soldring point.

making process is very easy and simple .

following components are needed to complete this project. 

40w soldring iron heating element .

40w soldring iron Tip.

DC gear motor.

5v DC power supply circuit(https://youtu.be/OekmLbkAQdA

or https://youtu.be/43mE8H05ikM)

3 ohm resistor .

push button. 

power cable. 

pice of PVC pipe. 

these are the following major components are used in this project.

How to make battery charger | 12 volte 10 amp battery charger

 

Welcome to Multi Projects, In this video I'm gonna make Heavy Duty Battery charger, This is automatic Battery charger(auto cut off). Output voltage is adjustable, you can adjust voltage according to requirement.

It's 10 amp charger so it charger any battery in very short time. cooling fan is also installed in this charger. It cut off charging and also off the cooling fan,when your battery will full.

in this charger we use 12 volt 10 amp transformer(Copper).

4 diodes (10 amp).

diode in4007.

capistor 4700uf 50V.

voltage regulator LM317

220ohm, 1k ohm, 15ohm  1/4W resistors. 

2 variable resistor 10k.

12 volte DC relay.

2 LED red,green 

cooling fan.

design the circuit according to circuit diagram, 

circuit diagram. 

use soldring station for best soldring. 

set you required voltage by rotating variable resistor and cut off to nearest point. I wanna charger 12v battery so i set 13.5 volte and cut off to the nearest point.

How To Make Spot Welding Machine

 

Welcome to Multi-Projects,In this project I'm gonna make spot welding machine. Using the old microwave oven transformer. By using this spot welder you can weld both heavy and thin materials. In this machine we have introduced extra socket for spot welding pan to weld thin sheets. The spot welding pen is also made in the this video. This machine is properly designed according to the working requirements. Almost the old components are used in this machine, so that the machine can be made at low cost. This machine is fitted with a cooling fan, so that the machine does not get hot from working for a long time. A 12 volt DC power supply is used for the fan.( how to make DC power supply  https://youtu.be/43mE8H05ikM ).
