CO2 or argon/CO2 for 3/16\" steel?


this is a quote out of HOBART website. so if i get a HOBART HANDLER 135 wire feed and use my POWERTANK with CO2- will this be sufficient for 3/16" steel or do i need the argon/CO2 mix?



4. Use the proper shielding gas. CO2 is good for penetrating welds on steel, but may be too hot for thin metal. Use 75% Argon/25% CO2 for thinner steels. Use only Argon for aluminum. You can use a triple-mix for stainless steels (Helium Argon CO2).

Re: CO2 or argon/CO2 for 3/16\" steel?

My welder, who is just about unreal with that mig, welds with 75/25 all the time. He goes from sheetmetal on a truck to 1/2 plates with the same bottle and welder. Also my best results with my mig was 75/25. It welded better but the welder was still the problem. Good luck

Can someone please bring me a hammer my 33's just ate my fender again. Damn i need more lift.

I have a Lincoln SP125 and use my power tank with CO2 and it works just great on thin and thick material. If you go with the Argon mix you will have to get another tank. But I think the CO2 if you try it will work just fine for most of your needs.

CO2 will be just fine for whatever you weld Steve and it's WAY cheaper than the mix. Straight CO2 does spatter a little more but not to bad at all. For home use ALL I ever use is CO2, because of the cash difference. Yes I'm a welder and if you didn't know look at the hobart books address and you'll see my hometown. We make those things here. Hell, I even dated the VP of the company's daughter for 2 years.(oops another story[img]/wwwthreads_images/icons/wink.gif[/img]) Also I used to teach adult ed welding classes at the local vocational school in the evenings.
Save your money and leave the mix for more specific welding tasks, and some cash in your pocket.
BTW if you ever decide to go to the Hobart welding school........look me up. I'm buying.[img]/wwwthreads_images/icons/smile.gif[/img]

Yeah, there all owned by ITW (illinois tool works) now.[img]/wwwthreads_images/icons/frown.gif[/img] Both are good machines. Actually the last 2 upper end welders I bought were lincolns. Their square wave 255 tig machine ROCKS for mid size shop work. All digital and soft touch buttons and a finese that just can't be matched by the other 2 companies for even another 1000 dollars.

PS......you'll really like the hobart BTW. It's great for a garage fab machine.

Re: CO2 or argon/CO2 for 3/16\" steel?

Also, buy it from http://www.cyberweld.com. They have the best prices I've seen, free shipping, and are nice people to do business with. I bought a 230volt Hobart Handler 175AMP welder, SpeedGlass Auto-Darkening Helmet, Oxy/Ace torch kit and Oxy/Ace bottle cart for just a few bucks under $1000. It came to my house a couple days later. The Hobart is a real fun machine to play with too. Pulled it out of the box and practiced on some scrap. Then my friend welded up a hitch for his truck and an entire exhaust system for his brother's truck. I'm hoping to do some body-work with it in a couple weeks.

Make it up as you go.
