Flux core mig welders?

landy-lee · May 22, 2021

Good evening guys

Has anyone here had experiences with flux core mig welders?

Im all right at mig welding with gas but never used a gas less flux core type welder.

I am thinking about buying one to do the repairs on my bulkhead.

Cheers Landy Lee

I've got one that I use for small jobs. You get a dirtier weld than with gas. But as my welding is bloody awful anyway, this isn't a deal breaker.

I've got an old machine mart one, never let me down, only time I've had a problem was when i got what only can be put down to bad wire once.

Mine is only basic but it does a job with a high and low power setting, with variable wire speed.
More choice of power settings would have been better, but I've always managed

Most gas MIG's can be set to do gassless .... swap the earth over basically.
Get a standard one ..... gas isn't expensive and a lot of suppliers will give you your bottle deposit back when you return the empty even if its a few years down the line.
If you want to weld on a hill in a howling gale, swap the wire for fluxed, otherwise use gas ....

My experience has been rubbish of there's a bit of a breeze.
Gassless is more convenient if you're not going to be doing much, or just occasional use

I have used one to fabricate some mud shields/inner fender guards for our 109. Welding sheet metal is tricky as you risk overheating and making holes. I practiced on a lot of scrap first. One tip I picked up from YouTube was to back up the weld area with a thick slab of steel. This absorbs excess heat and lowers the risk of burning through. Chunk of copper would be even better.

I use an aluminium slab when working with sheet material, really does help prevent distortion and blow-through.
