How did you make your spot-welding power supply? Can you show the insides and the schema please? I made several MOT power supplies so I'm ready to do the next step. I also purchased a small welding supply that I could use as a spot-welder, but I'm not sure if it would work or not. I bought also a controller with digital display for the spot-welder. Anyone seeing this can also answer and I thank you very much in an advance. Thanks Jaward for your videos!
Just got one of these welding pens. Told I can just use a car battery for the welder, but what is needed to power the 'plug part'? Guessing it just powers the internal timer/switch, so 12 volts? What is the polarity of the connector? Is the inside of the plug + or - ? I ask as I will probably just cut the plug off and wire it directly to power. Is there a way to figure out the plug polarity if unknown?
This is just a holder pen, means plastic + copper only. No circuitry inside. You will need spot welder for this. This is a good pen. If you have a MOT spot welder, check out my other videos if you don’t know MOT spot welder
Can you use a regular stick welding machine. I don't want to buy another machine. I have a plasma Cutter, mig welder, and a small stick welder. Any ideas? Thanks
NO Reason: Spot welding needs Voltage: 3-5v AC or 5v to 12v Dc Current: 600A-800A AC or 300-500A DC Working: output mili sec pulse Arc welder: 50-65v DC 200-300A Output current continuously
What is the principle of welding batteries? I understand the basics and that the welding spot should have the highest temperature for the shortest time. We have a spotter with a bunch of settings: first welding, second and third, where the second welding is the main welding and the third is hardening. There are also peripheral settings such as pause between pulses, current rise and fall times. So let's get down to business: the first and last welds should not have as high a current as the second. The first weld prepares the nickel strip for welding, the second welds it directly, and the third releases the strip. We have two main problems that I still can't figure out: 1. Why do the electrodes "stick" to the workpiece? According to my observations, this is due to the cross-sectional area of the electrode tip in contact with the nickel tape. On the one hand, a smaller contact area creates better welding, but the electrodes stick 👉👈 On the other hand, a larger area cooks worse. By increasing the current, the workpiece overheated too much and still nothing happened) 2. One electrode cooks and the other does not. In the case of DC welding, this is understandable. The "positive" electrode, where the current enters the battery substrate, welds better than the "negative" electrode, where the current leaves the battery. However, with AC welding, this is illogical for me, because the current flows back and forth across the workpiece. Maybe someone has a few gigabytes of information about welding batteries?) I want to absorb all the text from anyone that is related to welding batteries
Long comment 😁 , ok electrode sticks to workpiece , because you’re using common copper electrodes, instead you can use C14500 alloy Tellurium copper, which is relatively hard and doesn’t stick after weld. I have dual pulse spot welder , but I use single pulse for 0.1-0.15mm and dual pulse for 0.2-0.3mm , because output current of my diy spot welder is high and at lowest time and high current it can weld very well (Ac spot welder). I have few DC spot welders as well. I tired lipo batteries , which are good , but now I’m using 6S 500F (3000F) ultra caps, which is way better than lipo and AC spot welder. And single pulse is enough for strong welds. I even welded nickel strip to thick aluminium, and dual pulse have advantage there, like long preheat first pulse , and then high current pulse and delay between both pulses. Worked for me.
Hello! Sorry, i dont get what this black wire with jack is for, could you tell me?? Can i use this pen with another adjustable welding station (with not connecting that jack anyway)??
Thin black wire is used as alternative to foot switch , it’s a Normally open switch and closes when pen is pushed down during weld. This is just copper and plastic pen without any circuitry inside , this pen is used with spot welding machine.
I think it cuts off the flow of energy when it gets hit by the copper elements. So, it's a limit switch for people who like to keep the welding pen on the batteries for too long and don't remember while doing so that the battery can go boom.
Hello dear! I have the same pen. But my spot welding machine doesn’t have the port to connect that middle (black wire on the pen). Plz tell me how could i operate that pen with welding mashine wich has only +/- INN and +/- out? 😳
Hi Jawad can you please do a favor can you provide all the dimensions of this product like diameter and of the springs, thickness and width of the copper plates, and the dimension of the blue box. i want to make this as this product is not available in my country and the cost of importing this is very high as high as thrice the price of product so can you please give me the dimensions.
Hello, thank you for sharing, I bought the same product, I want to ask where did you get the power connection unit and how many volts are we giving to the middle cable?
I have the handle pen welder but need a power source unit what is a good one
Thanks for the vid btw. Great work.
This music moves me to other world. Makes me cry. Ohhh 😪
Congratulations on 100 subscribers 💚
Hi Jawad, what Make & Model Number is the Power Unit you are using for the Spot Welder Pen please?. Thanks.
Excellent
Is the any way to avoid black discoloration
Thanks
thank you .... .black discoloration can be avoided when amps are high (800+ AC , 300A+ DC)and time is the lowest and tips are clean and balanced .

Inside of plug is positive
can I run it directly to 220 volt
Can you use a regular stick welding machine. I don't want to buy another machine. I have a plasma Cutter, mig welder, and a small stick welder. Any ideas? Thanks
NO
Reason:
Spot welding needs
Voltage: 3-5v AC or 5v to 12v Dc
Current: 600A-800A AC or 300-500A DC
Working: output mili sec pulse
Arc welder:
50-65v DC
200-300A
Output current continuously
What is the operating voltage and is the voltage ac or dc required for this handheld please
I tested it with AC 4v 600-800A
Can also work with DC
i can connect to the batery of car??? and then the suplie 12 volt too ????will be work??
silly question, but where does the little 12v looking plug go? Do i plug into another 12v psu?
Dc jack is just a trigger switch , this pen needs spot welding machine as input
Nice welds

if i connect that welding pen to normal welder (not spod welder) will it work? or it wil continually weld and that would be not good?
No. It won’t work. You will need a spot welding machine for this.

I'm using new 230cc lawnmower battery and works great just like the person showing us. But can't promise will work on every battery ...

can i use weld arch machine for source power to this device
Alli regardo no.
Is this dc 12 v or ac 220v i am confuse i have this but don't know how to use it
This is just a pen, without any circuit inside - you will need a spot welder for this. AC or DC

Can we connect this to a welding machine
For soot welding machine only
hello, what is the small cable from the welder for? where you connect it to your power supply? nice video.
Simple switch for trigger
@@JawadAhmadsahibzada Its just for shorten when trigger is pushed by the welding "probes"?

5 amps? 😂

Hi
Can I ask how you have connected the spot welder please.
Pen is connected to the two output wires of spot welder.

Yes. It’s just a pen for spot welding machine.
what is the power source??????
MOT spot welder
how to give power to it
it's just a pen, you will need a spot welder to weld with it.
