Another I-140E Question

Hello Everyone...............

According to specs, the 140E can do .35 wire. I bought a roll and some tips recently and trying on 12g steel, couldn't find the bacon anywhere.

1st.. I'm new to welding so it may factor in but I have no problem finding the sound when using .23 / .30 wire
2nd.. I use the wife's washing machine outlet when welding. It's 120 on a 20amp breaker.

I understand that to get the best performance I should be on a 30amp breaker.

Question: Unless I constantly trip the 20amp breaker (which I haven't yet) is there really a need to go with 30amps since I don't think I'm loading the machine.

As when using the .35 wire on the 12g steel, I went up and down both dials but never found a stable sound. I was grounded to the work and not the table. I used a flapdisk to clean the steel and then used cleaner and a clean rag to wipe it down. I use 75/25 gas and it was set to 20-25.

As in #1 above it may be operator error but I think I covered all the bases. And since I wasn't trying to weld up a Sherman tank body I figured that the 140 would be able to run the .35.

Thanks Gordon

Are you using .035" drive rolls, or just the stock ones?

I'm using the stock wheel which came with the unit. According to Everlast, it's supposed to run .35.

It'll work in a pinch on the larger welders, but for the 140E you need the most stable feeding you can get. Also make sure you have the .035" tip.

If you never exceed 20 amps and never blow that breaker there's absolutely no reason to be on a 30 amp breaker. I know someone might talk about voltage drop, blah blah blah, but the bottom line you'll be fine!

Yes, there is. You can cause overheating of your wiring. This can create fire dangers. If you do have a trip, each successive trip, the breaker looses it's rating. Voltage drop is caused by running electricity a long ways.
