We've got a bunch of sheet metal clips to attach to 2mm stainless steel rods.? Hmm, how to do this.

Then I hit on it.? We have a Docreate spot welder for making up battery packs (like 18650 cells).

I dialed it up to FULL POWER and tried it.? Even without cleaning the metal I got a decent weld, couldn't pull it apart by hand using moderate force (any more and other things would break).

So, spot welding it is.

That Docreate welder seems like a nice machine.? Well thought out and works.? We haven't had it too long so can't say how well it lasts, but it also wasn't expensive.? They sell a range of welders, here's the one we have

2mm is is about 14 gauge .

For short run I use a mig welder.?

Maybe pug welding inthat gauge.

?

Spot welders are great tool? but heavy gauges takes a lot amps in thousands amps to do weld correctly.??

.

2mm is rod size opps?

?

What gauge is metal ?

_

That is 0.012"?

Very hard to weld . The only way I ever did was silver solder to avoid buying the correct equipment found in electronic industry. I was in heavy steel.?

?

What are you building??

It's a bunch of clips that hold paper.

this thickness is close to the range of battery packs, only for batteries it's nickel to stainless.? The nickel comes in 0.1mm, 0.12mm, 0.15mm, and 0.2mm.

That tuff one main reason is keeping the cost down.?

They make good equipment for this work but all cost money.?

It sounds like for advertising. I do not know the number you need ,look at soldering for a low production number.?

For larger number look for company that does for advertising.?

?

Very thin is very difficult with its own problems.? Heavy has very different problems that what did most life.?

Thin was just hobby in one's and two's and level is different set of problems.? This one I a roll of very strong silver well solder bandsaw? blades and a low temperature silver solder. Both Great for a few parts.

?

How many do you need to make?
