HI Folks
After a bit of advice - Is it possible to convert a gas mig welder (SIP MIGMATE 100) to use the flux core wire for outside work ???
Ive had a gas mig for years but always used gas with it - but moved house and no longer have a workshop/ shed just a wooden shed / workshop in garden so have to do bits of welding outside

I didnt want to have to buy a no-gas/gas mig as mine is ok

Im sure when I got the mig 15 years ago or so it said just put the flux wire in and change the tip to 0.8 and off you go !!!

I know the newer ones say to reverse the polarity but would this make a great deal of difference ??

Anyone just put the flux wire in and did it work ??

Will be welding 2-3 mm steel for brackets etc

Appreciate any advice

thanks
johnny

I thought you just stuck the wire in and away you go...but never tried it and from what I've read the welds aren't great with fluxed wire.

Could you not shield the job from the wind or just weld on still days?

You need to change the polarity, for gasless wire you should be running electrode (wire)negative. It would normally be setup the otherway. The gasless takes a bit more burning to get a good result. The power is split between the return (earth) and electrode. The + carries approx a third of the heat, the - the other 2 thirds.


Its probably changeable with a bit of fiddling, not sure.
The gas/no gas machines tend to have simple dinse connectors to switch the polarity.

Im not that familiar with the gasless wire, never really used it.

If you need any more info, might be worth having a read round here- http://www.mig-welding.co.uk/
