i have a hobart handler 140 with flux cored 0,030 wire and i have alot burn through on anything thinner then 18 gauge steel ,would switching to gas and soild wire help with this problem ???? ive been told it would ,but thought id ask you guys since you seem to know what your talking about and do nice work . like i even have troubles with exhaust pipe ,i noticed its way better if i turn up the heat and giver **** ,if i have it on a low setting it will burn through eventually am i doing something wrong here ??? im pretty new to welding ,so if i seem like a noob ,its because i am


if anyone has any tips or tricks for this welder or anything like that can you please help

id greatly appreciate it


thank you

 

While I'm no expert with a MIG, I will give you my experience when switching from fluxcore to gas/solid wire.

When I first got my little 120v machine I used the fluxcore for exhausts, IC piping, aka 'thin' stuff. With some practice I managed to get by, but the welds didn't look that great. I felt like I was spending more time worrying about splatter.

The minute I switched to gas I began to notice the quality of my weld a lot more. When I had the fluxcore I couldn't really see under all that splatter .

I also found that slowing your wire speed, turning the heat up a titch and working faster also gives you a better result.

I wouldn't bother with fluxcore if I were you. Make sure the joint is clean. Keep your wire speed down, keep your heat up a bit and work faster.

 

The fluxcore is your problem. It burns much much hotter than solid with gas.

Switch to 24 thou wire and C25 gas.

 

It's easier to mig the thin stuff than it is to flux core it. When you switch over to solid wire I would recommend .030 wire. It will work wonderfully for the thin stuff and still allow you to weld the thickest steel your machine is capable without changing anything over.


Also try welding in the vertical position progressing downward. It makes it much easier to avoid burnthrough.

 

Switch to gas first of all, for thin sheet metal use .023" wire it will let you weld a little longer before it burns through.

 

thanks for all the replys guys i guess im off to buy some goodies lol ill just keep the 10 pound spool of fluxcored wire for windy days i guess welding out side
