Snapped a couple pictures at work the other day of a few things. Using a Miller CP-302 with a wire feeder using .035 wire 82/18 argon/co2

large rollers i was welding while a guy i work with was turning it.





I do a lot of tig work too but don't have any pictures on my phone. Not my best work, just happened to snap some pics the other day.

Most fab shops use straight CO2. Burns slightly hotter then 75/25. Straight CO2 is cheaper too. I was going to make the switch, but the regulators for 75/25 are not compatible with the CO2 tanks, so I am holding off until I finish my current tank. Then I'll buy a new regulator.

You usually also get a little more spatter with CO2 vs. 75/25, but if your wire speed and amperage are dead on, you should have very minimal spatter.

Speed charts also differ, so before you jump in to changing, make sure you check your speed/amperage charts as the weld settings for the material you are welding will likely change.

Found this when grinding off some welds that were supposed to hold the rear crossmember onto the back end of the frame. Not sure if it was the p.o. or the factory but somebody left some swiss cheese...

Hard to say...but I can tell you that the factory welds were far from being perfect.

It runs really well on straight c02, you get slightly hotter welds compared to c25. I've heard that using the bigger machines on straight c02 creates more spatter though.

I may look into it for my home machine once i pick up a bigger machine.

I set the machine by sound and site over using a chart, don't usually like the suggested settings, i tend to burn a little hotter usually.

You can use a cga-320 to cga-580 adapter to use a c02 cylinder with your argon/c02 regulator. If I can find a part # I'll post it.

Not the Greatest, but not the worst either. a few welds, a few different ways.

miller 200 MIG welder, .035 wire, 75/25 mix gas. 45 wire speed, welder on amp setting 5 of 6.
weld pattern #1, Pushing the puddle, circles


#2 pulling the puddle, Circles


#3 pulling the puddle, weaving


Pushing the puddle, C motion


and lastly, my attempt at TIG. Hobart 165 TIG. I have very little time on TIG at all, this is the longest continuous bead i have ever ran on a TIG



Material is all the same. 1/4" steel plate welded to 3/4" x .120 wall DOM tubing.
