Shielding gas or not?

Post by TheBigToe » March 19th, 2019, 11:37 am

I have a Hobart Handler 140 I picked up at a pawn shop. It didnt have the gas regulator or shielding gas bottle. Looking for input on purchasing a regulator, hose and bottle or simply continuing to used flux wire.

Some place like Tractor Supply, one of the fleet farm stores, your local welding supply, Or online like CyberWeld.com.

Flux core isn't necessarily bad, useful when welding in a breeze that would blow away the shielding gas.

IMO, it would be worth the $100. Flux core will glue it together, but using shielding gas will get you cleaner welds with less hassle.

Double yea that.

I absolutely hate flux core. You will find the gas produces a nicer weld and the splatter is decreased greatly.

A bottle of gas will last a fair amount of time but bigger bottles aren’t much more to fill than the smaller ones. I run two 80cuft bottles so I always have a full one. Most places like airgas will let you change up/down on bottle size by just paying/refunding the difference in case you ever want to switch.

I agree with DT. I recently bought a second bottle because you just can't run out at a good time.

I use C02 on my Hobart 140.
You can find a 20 lb C02 bottle cheap. They are the ones used on the fountain drink machines.
I will never go back to flux core.
Im a novice and only weld a little.

So co2 is better than argon?

I personally wouldn't waste argon on MIG. Maybe a co2 argon mix but I keep the pure argon for Tig stuff

CO2 is not better than argon, just a lot cheaper.
I agree with Diggerg.

Gas depends on both process and metals.

I've got 2 bottles in the garage for the MIG for mild steel and stainless, as well as another for TIG.

I use c25 for welding carbon steel, it's pretty cheap and does a good job.

I started with co2 and keep a bottle around as i find it better for welding outside. For the shop, I keep the 25% co2 /75% argon mix. On my last exchange, I gave $38 for a 80cuft cylinder.
