# Is it safe to touch 8 volts?

Let me say first that i'm a noob in electricity. I measured the voltage from my diy microwave-transformer-welder and it was 8. I have no idea how much amps run through it but the fact that it creates lots of sparks and can create welds on metal may suggest that it is a high amount of amps. Is it safe to touch this or do I stick to my gloves?

Edit: I added an image of my setup, that 230V AC is 16A.

• Interrupting large currents in large inductances can produces transient voltages much much higher than what your slow multimeter can detect. Mar 24, 2020 at 21:15
• A warm welcome to the site. The answer to your title question is: yes, it is safe to touch 8 V. Whether it's safe to touch what's coming out of your microwave-transformer-welder is another question. We can't be sure it's really 8 V from the little detail you've given us. Unless you're certain it's 8 V, TAKE NO CHANCES, DON'T TOUCH IT and stay safe. Again, welcome. Mar 24, 2020 at 21:25
• P=V*A. 230v*16A = 3.7kW. A=P/V. 3.7kW/8v = 460A. Mar 24, 2020 at 21:30
• I’d be more worried about those exposed wires on the 230V side. They’ll kill you. Mar 24, 2020 at 22:20
