Thanks for watching !

my welding teacher sent me this video thanks for the informal video!

[jarialshurfield]

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

[NickDanger]

I love my pro spot it’s expensive but it’s so worth it!

[JFRSTR]

Great video! Very informative and right to the point.

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.

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.

I could really do with one of these, sure as hell beats drilling out plug welds. Looks way quicker.

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

[georgejones]

I got the 120 volt and it seems pretty decent

[mikemuniak]

Great video, question do you think the 120volt version Will work as strong as that ?I'm thinking bout buying one

[bee]

I was looking at the 120 version as i dont have 220. I think the 120 is smaller diameter spot welds

[eddyboh]

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?

[sledsports]

I wonder how involved fabricating custom tongs sets for different applications would be?

[sashiboy]

Great video, I've never seen this type of welder, will this type of welder get the metal too hot and warp it?

[alicenaillis]

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

[brittanywright]

What is the max thickness that the welder will work on?

[dougbaker]

How do you like the Harbor freight spot welder ? Not much luck with Harbor freight for me .

[kevinhowe]

My instruction manual says to use welding glasses with these. Do you suggest this?

[Fgcamaro]

Hello where i can find the sem weld thru primer?
