How to convert a 240v gas mig180 welder to pure DC to use gasless wire

AI Thread Summary
To convert a 240v MIG welder to use gasless wire, it's essential to understand that MIG welders typically already output DC, as the 240v AC is converted internally. The discussion highlights that using flux core wire does not require any conversion, as it is simply a different type of shielding gas. Contacting the manufacturer for specific guidance may be beneficial, but the need for conversion is generally unnecessary. Clarifying the meaning of "pure DC" is also important, as it may lead to confusion regarding the welder's capabilities. Overall, MIG welders are compatible with gasless wire without requiring modifications.

Has anyone got any ideas on how to convert a 240v, mig, 180amp, welder to output pure DC to enable the use of gasless wire.

Not a clue. Maybe try contacting the manufacturer of the welder?
 
What do you mean by pure DC? MIG welders already output DC. The power source is often 240 volt AC which has little to do with the output.
 
Are you talking about using flux core wire? You shouldn't have to convert anything, they are just two different types of shielding gas. the 240v is converted to DC internally.

Thread 'Weird near-field phenomenon I get in my EM simulation'

I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...

Thread 'EMF (Electromagnetic Field) & EHS (Electromagnetic Hyper Sensitivity)'

Hello dear reader, a brief introduction: Some 4 years ago someone started developing health related issues, apparently due to exposure to RF & ELF related frequencies and/or fields (Magnetic). This is currently becoming known as EHS. (Electromagnetic hypersensitivity is a claimed sensitivity to electromagnetic fields, to which adverse symptoms are attributed.) She experiences a deep burning sensation throughout her entire body, leaving her in pain and exhausted after a pulse has occurred...
