Inductance adjustment for MIG - The 1947 - Present Chevrolet & GMC Truck Message Board Network

**dennislbrooks** · 02-23-2022, 09:43 AM

I weld, not a professional welder but have been welding for a good while MIG, TIG, and stick. I bought another welder that has an Inductance adjustment for MIG. Did some reading and most (hobby- lower cost) welders have this preset with no adjustment. May be kind of a neat feature to adjust penetration.

Anyone have any experience with this feature?

I read also where it enhanced the use of 100% CO2 shielding for migging low carbon steel. My new welder indicates that 100% CO2 can be used with it.

Anyone use 100% CO2 at home?

Sounds like a neat feature for welding body panels to me.

I have read a few things on it, and I understand it less now. Somehow 🤔

I started out about 40 years ago using 100% CO2 and one time tried the 50/50 mix of Ar/CO2........been with it ever since. Now that the prices are getting stupid I may go back. I don't weld anything seriously structural with the MIG. Anything structural I'll step back to Big Red and a box of sticks

I got a CO2 set up for my mig for cost, and besides a little extra splatter. It works for what I do with my Hobart 220 MVP.

At that time I did hvac service so I had practically unlimited C02 access.

I asked my supplier and he has no customers that use 100% CO2. (out in the country and a small supplier) I will ask him if he can supply me a 20lb for testing sometime. As I understand the inductance adjustment is turned down for just co2.

I tried 100% argon and do not like it for mig steel. They gave me a 100% helium by mistake once and I thot I forgot everything I knew about welding MIG mild steel. I can use the 100% argon for aluminum and stainless TIG.

My new welder is a Lift TIG. I have not tried it yet.

My Hobart has no issues with CO2 vs my other Hobart with standard mig gas. Other then a bit more splatter.

You will need a regulator for CO2, but they are less then a $100.

The good news is a typical bottle last almost twice as long and cost about 1/3 as much.
