Thanks for watching !
my welding teacher sent me this video thanks for the informal video!
Awesome ! Thanks for the comment.
I'm so glad you are using the Chicago tool one. I have been wandering how well that one worked. Spot welding is so effective for overlap welds
It's a great spot welder ! I just upgraded to longer tongs, even better. Thanks for watching !
I love my pro spot it’s expensive but it’s so worth it!
Great video! Very informative and right to the point.
Thanks for watching !
Another great video. Keep it up. To make good quality spot welds you have to make the welding electrodes to be coaxial when the welding materials are between the electrodes & the proper clamping force is applied. Sparking is not normal and could be dangerous ( proper protective gear is a must ). The factory supplied upper tong end has to be bended more to get coaxial with the bottom end. It is obvious that for every thickness of welded materials you will have to use different diameter / length welding tips & set up their alignment individually. A timer is also a must for good quality spot welds. There are timers with welding time compensation. These are monitoring the welding current and adjusting the welding time accordingly.
Great video thanks
Thanks !
Very good
Thank you for watching !
Thanks for the video, I was wondering if I had to drill a hole for the spot welder I guess I don’t. I just got me the 240 on sale
Awesome you will really like it ! FYI Ebay and welding shops sell longer length and different configuration tongs. Thanks for watching.
I could really do with one of these, sure as hell beats drilling out plug welds. Looks way quicker.
Christmas is coming, gift yourself one..... you'll be happy with it! Thanks for watching !
have you tried removing spot welds with this by giving it too much heat? I guess that would trash the tips... Just curious...
I used a Miller 120V spot welder on my 66 Mustangs rear speaker deck. Then I heard some car guys said that it can be dangerous to use the cheaper spot welder and that they had to invest in a 6-7K spot welder. So I'm not sure... I did test my spot welder on 4 sheet metal patches and spot welded them together...3 out of the 4 sheet metal patches couldn't rip apart with pliers. I guess it would be safe as when I spot welded 2 sheet metals together and tried to pry them apart it ripped around the weld which means the weld is strong enough to hold if there is impact to the car. I also had to use the 18 inch welding rods as the 12 inch welding rods that came with the spot welder wouldn't reach the area...Just glad it looks Factory correct. I do have a Lincoln MIG welder, but definitely prefer this one for spot welding as its a much cleaner job and far less time to prep and no need to grind off access welds.
Those " car guys " are spreading misinformation..... Thanks for watching !
Actually it is low voltage in theory @@guzzifabrication3448
I was looking at the 120 version as i dont have 220. I think the 120 is smaller diameter spot welds
I haven't tried the 120V but I've heard it works well.
I got the 120 volt and it seems pretty decent
Very cool I was curious as how well those worked. I wonder if the 110-unit is lighter than the 220
For thinner metals, e.g. .025 or so, the 110 might be easier to control…
Hello where i can find the sem weld thru primer?
Well that's very cool!! I have a 60 model Chevy truck and I was going to weld some parts together with my mig but I think I'm going to invest in this spot welder and try that out. Where did you buy that and what brand is it? Thanks
I bought the resistance welder in the video is a Chicago Electric ( I would go with the 220v not the 110v ) that I purchased at Harbor freight, I'm very impressed with it !
Great video, I've never seen this type of welder, will this type of welder get the metal too hot and warp it?
The longer the welded is activated the more heat that will be produced, but it doesn't get hot enough to warpage.
This is exactly the same technique that has been used in car body manufacturing for decades.
I wonder how involved fabricating custom tongs sets for different applications would be?
I was just trying to work that out yesterday, that's crazy, They have different configurations and lengths on Ebay from $45 to $250. After time, material, learning curve, I decided to just purchase the pair I need.....
@@guzzifabrication3448 I was thinking 4130 steel tubes and run battery cable out to the tips how ever long you need them, in what ever configuration you need them.
@@BrilliantDesignOnline Let me know how that works out.
Great video ,question do you think the 120volt version Will work as strong as that ?I'm thinking bout buying one
I haven't tried the 120V, but I've heard that it works really good, maybe search for 120v use on youtube.
How do you like the Harbor freight spot welder ? Not much luck with Harbor freight for me .
I really like it and you can also buy different lengths and configuration of tongs for it, I don't use it everyday, the important thing on equipment like this is not overheat it, I think it will last a long time. I just couldn't justify the price of the Miller or other higher in brands
@@guzzifabrication3448 yeah prices on stuff are through the roof . Keep up the great work .
What about if you don't have the other side to clumped it to, how do you work then with one tooth of the spot welder?
Simple it won't work.....
@@guzzifabrication3448 So, they cannot work independently from one another?
@@eddyboh2723 It takes both tongs contacting the allow the current to flow and "melt" form a spot weld. Thanks for watching !
@@guzzifabrication3448 Sure, but what if you connect the second welding tip to a high voltage cable line and clamp it to the sheet you'll be welding?
My instruction manual says to use welding glasses with these. Do you suggest this?
I recommend safety glasses and a face shield, a shaded lens really isn't necessary unless that's what you were instruction manual says you should do.... always follow the safety manual
will that spot weld through body glue
Not usually....
What is the max thickness that the welder will work on?
18 ga
Price please
Price for? Shop rate? resistance welder
