Re: Using A 4 1/2" Grinder To Cut Off

I have A though D  I use D for 1/8 and up and C for most everything else


If it isn't broken..... modify it anyway!!!!

Re: Using A 4 1/2" Grinder To Cut Off

Day, do you think 15 Amp service or cheap wire may be an issue? I get a lot of popping!

Re: Using A 4 1/2" Grinder To Cut Off

No if the amperage was to low the breaker would pop.  I would mess with the gas settings, see if that makes a difference.  Mine are not set were recommended but rather where they work best

Re: Using A 4 1/2" Grinder To Cut Off

I went through it all. Polarity, checked the connections, turned the gas up/down, slowed the wire. I actually got a so so weld. I had tried a guys Miller about a year ago. It worked real nice, not like this, however I do think it was a higher amp 110V. I read, it may be cheap wire.

Re: Using A 4 1/2" Grinder To Cut Off

maybe mine is higher amp, I will look today.  I use wire from harbor freight so you can't get any cheeper than that

Re: Using A 4 1/2" Grinder To Cut Off

I am running a 140 Lincoln, I like it and it does very well with either flux or gas. I had a 135 , we never could get that one to dial in like it should have, fortunately some sob stole it. My bro has an older 125 I think it is, use that primarily with gas and it does great up to 1/4". I guess my point is ,, the welder may not really be functioning correctly if you cant get it set right. I do run a 20 amp circuit and 12 ga. exstension cord, low voltage will make them sputter. I don't know your shop , but I noticed that alot in our old shop where the lights were on the same circuit as a couple outlets. Changed outlets and it ran smoother.

Re: Using A 4 1/2" Grinder To Cut Off

I guess this should be filed under, "kids don't try this at home." I have a clothes drier right inside the door. I need to make an extension anyhow, if I go with a 220V unit. One leg at 30 amp? Hmmm....... Then maybe if I had that NASCAR sticker on it?

Digz your not the first I have read that improved connections. I read a guy had just made his own heavier extension and his problems disappeared.

Re: Using A 4 1/2" Grinder To Cut Off

I accidentally came across Jodie's vids. I used to work with this guy, he retired about a year ago. He ran our welding school, certifying our welders.

Re: Using A 4 1/2" Grinder To Cut Off

Well I have it hooked up. It still pops, but my welds look flatter and smoother no holes more even. Need more scrap to practice.

Just read on the inside of the door. For max use, 25 amp service required.

Re: Using A 4 1/2" Grinder To Cut Off

Question,
When you read the specs on a welder, in particular a 220 welder. Input reads something like this, 230 volt 50 amp. Is the 50 amp a total or per leg? My guess is the total.

Re: Using A 4 1/2" Grinder To Cut Off

it is the sum.  A 50 amp 220 volt circuit breaker is two 25 amp breakers tied together to provide you 50 amps at 220 volts.

Re: Using A 4 1/2" Grinder To Cut Off

I don't think that's right Day. I'm pretty sure a 220 breaker is rated for the amperage per leg, so that for instance a 20 amp 220 breaker is the same as two single 20 amp 110 breakers. Some older style breakers had a hole through the switch handle. You could gang them together with a long #6 machine screw and a spacer to get a 220 breaker, or even a 3 phase breaker for that matter. When you check a motor for current draw each leg has to be below the rated value of the breaker or it will trip.
