Short Circuit vs Spray
Which one is better?
Short circuit mig is the most commonly used mig welding process for general fabrication welding.
Why?
Because it is more versatile than spray mig.
Spray mig has it’s place… like for welding railroad box cards and such. But for general fabrication and repair welding, short circuit mig rules.
The small 115 volt mig welders that you can buy at home depot and lowes use short circuit mig process for welding thin sheet metal , all the way up to 1/4″ thick steel.
Mig welders like the Hobart IronMan 230 that you have seen in my recent videos also use short circuit transfer.
Short circuit mig has received a bad rap. It’s a good process but it is desribed by many textbooks as being the most likely mig welding process to have lack of fusion problems.
That’s because short circuit mig… more than any other welding process, depends largely on the welder to set things up right and to use the right mig welding technique to achieve a good weld.
Spray mig is another story.
It’s hot… very hot.
Spray transfer mig is useful for production work where high travel speeds along with deep penetration are the most important factors.

I am new to welding & am hooked and subscribe to your youtube channel. I recently purchased an Ironman 230 and hope to get my skills to a point, to use it to weld some 3/8″ steel control arm brackets on to an axle with up to 1/2″ tube wall thickness. The Ironman 230 literature claims it can weld up to 1/2″ steel. Should the weld I just described be done with short circuit welding, or is spray transfer required on 1/2″ thickness, or is it really a matter of choice as either will fuse the metals properly if the weld is executed properly?

I like Everlast welders, but what kind of Mig welder did you use in this video?
When do you use Mig welding and Stick for different metals?
I am in the process of buying and Everlast Stick/Tig and Plasma which one do you recommend for the hobbyist welder?
Thanks in advance. I am hooked on your web.

Did you create video of everlasting plasma cutting?
