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

Click For Summary

Discussion Overview

The discussion centers around the conversion of a 240v MIG welder to output pure DC for the purpose of using gasless wire, specifically flux core wire. Participants explore the technical aspects of the welder's output and the necessity of conversion.

Discussion Character

  • Technical explanation, Debate/contested

Main Points Raised

  • One participant inquires about methods to convert a 240v MIG welder to output pure DC for gasless wire use.
  • Another participant suggests contacting the manufacturer for assistance, indicating uncertainty about the conversion process.
  • A different participant questions the need for "pure DC," stating that MIG welders typically output DC and that the AC power source does not affect the output.
  • Another response clarifies that using flux core wire does not require conversion, as the welder already converts 240v to DC internally.

Areas of Agreement / Disagreement

Contextual Notes

Participants have not fully defined what is meant by "pure DC," and there may be assumptions regarding the internal workings of the welder that are not explicitly stated.

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.
