    My probes. This is a re-purposed set of hose clamps from sears. The welder is only as good as the method used to apply the welds.

    My Build I started with my old gateway box - it was free, but difficult to clean out! They don't make computer cases like that anymore! +-3 Farads of rockford fosgate caps. Going through an ebay SCR and a lot of components. This took some time to build and troubleshoot. Weeks of effort...

    re: SCR Trigger I simply hooked up my system similarly to Jeremy's diagram - although I used a 10ohm resistor. All seems to work well for triggering so far.. although my relay only works at 6.25v and above. Utilizing the welder below 6v is not possible... but then maybe I don't need / want to...

    SCR Trigger Subtleties? OK - so I read Jeremy's post and diagram showing a 8.2 ohm resistor between the capacitor voltage and the input lead for the trigger. This seems to allow a lot of voltage to the trigger. I don't know what Jemery's SCR is rated for - but mine is rated for 3v @ 150ma. I...

    I rigged it all together and tried some material. I can join .060" wire fairly well @ 21v - but worry the caps will blow. 50% more umph would be very helpful - then I could get something done. If the capacitance is so far off - likely the 24v volt rating is too. What happens when caps are...

    Hi All, I read all 57 pages of this debate. Some very interesting reading - and amazing welders. Thought I'd try a low-$$ build - although not welding for batteries. I need to join .060" dia stainless rod for artwork I'd like to make. Someone suggested that I might need approx 250 watts/sec...
