I have a one man artisan business.
I have stick welded for ages but I am now looking at spot welding for a particular purpose and
I want to see if it will/may work before I spend money on (used) equipment.
All metal is low carbon mild steel, high draw type CR04 1mm thick my supplier says is the same stuff that car enthusiasts use for panel repairs.
I want to spot weld a small 1 cm diameter cup face down onto a flat sheet.
If you scale it up then it would be similar to putting a whiskey glass upside down on a table (so that the glass rim was fully in contact with the table ) and then placing electrodes one on top of the glass and one underneath the table and to weld the glass to the table. I will drill a tiny vent hole just in case air pressure were a problem. I will be sanding down the "rim" so that the cup and table fit flush before the weld.
The weld does not need to pass strict tests, if it cannot be pulled off by hand it is fit for purpose.
I was hoping I could get away with a hand held spot welder in the 500 pound range? Is that a fair expectation?
I will be doing the same thing repeatedly so its not a "one-off" - I can't use glues or adhesives or brazing.
Thanks for any advice given
