im starting to build a spot welder possibly and/ or ach welder, has anyone made one or has anyone had experience building a similar type of device??? sorry about not a lot of info, i don't have that may ?'s as of yet

 

No experience with "form a mot" or "ach welder".
My advice is be more explicit, provide more information, use clarity, spell legibly, use caps key and punctuation properly and proof read before you post.
Other than that good luck finding a mot & ach.
