first make sure your spool gun connection is correct, if you are using flux wire connect your spool gun power wire to the - negative connector on your machine, if you are using gas then connect you spool gun power wire to the + positive connector on your machine.

make sure your gas pressure is around 18-25 (what works best for you) when the gun trigger is pressed.

have the correct gas for your base metal.

for steel you want 100% CO2 or 75% argon and 25% CO2. *dont use 100% argon
for aluminum you want 100% argon.
and for stainless you want tri-mix argon-CO2-helium.

don't use flux wire with gas.


other things you should check:

make sure the nut holding your wire spool is not to tight or to loose.
check your wire tension.
make sure that the wire goes thru the contact tip smoothly.
this is all i can remember now but others can chime in.

machine settings:

im not familiar with your machine but you can download a mig booklet from the Miller website, the troubleshooting guide with drawings will explain power, wire and travel speed a lot better than i could.

Bird **** looks better than that man lmao. It's not your fault though. Soemthing is seriously wrong with you rmachine or your setup.

what are you voltage and wirespeed settings at? You could very possibly just be WAY to cold and have WAY too much wirespeed causing th wire to hit the steel arc off of it, bounce and repeat.

Verfy all theings ROTARY mentioned and share your setup.


PS You can use shielding gas with certain types of flux cored wire.

What was wrong with it?

i didn't know that, you learn something new everyday!

 

Why would you want to use shielding gas with flux core wire?

 

because it runs hot and you get mad pentration and can move faster it has less splatter and a higher deposition rate.

so in short it's awesome for structural steel.

I might go setup my mig for it and take some pics today if I get real motivated. Don't count on it though.

Starting next monday I'm going to be at a new job doing pretty much FCAW and dual shield all day.

FCAW has a higher deposition rate than GMAW, but GMAW has a way better weld appearance.

When you have gas shielded FCAW, you get the higher deposition and a much better weld appearance than with just FCAW alone.

yes you would close the valve on the bottle. Then take the regulator off.
