Welder and electric question

[thecrow1]

So I had a flux welder for years served me well. I just bought a 225 titanium stick welder from harbor freight. I have 100 amp service with very few breakers in the service panel, I installed a 240 volt receptacle with 6 gauge wire with a double pole 50 amp breaker. So if I fire the welder up on 240 volt with really nothing else on I should be able to get some decent welds on mild steel? I’ve found some videos on YouTube of a guy using same machine to weld some pretty thick metal with only 110 volt. If I set it to let’s say 75-90 amps on 240 I should not trip the breaker? I have various rods available so just looking for advice also upgrading it to 200 amp isn’t in the cards thanks in advance

You should be able to weld on max output with no breaker troubles if you're on a 50A circuit. You'll probably only need about half that for most 3/32 and 1/8" rods.

That sounds good I’m going to give it a try I do have some thicker metal projects I’ll see how it pans out thanks

Inverters are pretty efficient. The titanium 225 draws 42 amps at max power on 240 volts. Should be plenty of headroom on a 50 amp breaker and #6 wire is rated to handle it as well, especially for a short run.

Go nuts!

Wow I didn’t know that so i should be able to do sun 3/16 , 1/4 steel? I have a bunch of Clovis hooks to weld to my skidsteer bucket what would be the best rod and settings for my machine? If this only runs 45amp I will be golden ty

Did you mean clevis hook? Also known as a chain grab hook.

Something like this sorry spellcheck got me

I'm not a stick welder, sorry. Others I'm sure will weigh in on the best parameters.

The duty cycle will water down the 42 amps, and thus the thermal load on the wire and breakers.

Check the Code section for the applicable multipliers; and check the welder's owner's manual for guidelines on wire and breakers.

I think I may be able to weld short runs w/out the duty cycle cutting me off but we def will see.

Unlikely.

What I meant is the machine uses less power over a time period that the primary current rating would suggest.

The big issue with cheap welders is duty cycle. Couple minutes on. Several minutes off.

Check this out

Right, so 42A is at 20% duty, and 19A at 60-100% duty.

Somebody familiar with NEC can apply the particulars from the welding section for circuit sizing.

Fwiw, I run a millermatic 211 (24A rating) on a 20A circuit for convenience. In 10 years, I haven't been able to work machine hard enough to nuisance trip.

youll definatly need it plugged into 240. otherwise your limited to a max output of 70a on 120v input ( and only 4min of weld time). thats assuming it truly puts out the 70a (some cheaper machines dont even put out the advertised amps).
but hooked into 240v it should weld those clevis hooks no problem

Set your heat at 115/120.... Grab some 1/8 7018 rod and go to work.... You should be fine....
I have a welder that looks very similar to yours (different brand name) that runs 1/8 7018 VERY smooth at 115 amps....
