Anything welding

There is no Code requirement for the outer sheath on NM (non-metallic, e.g. Romex) to be color coded. So you shouldn't trust this. It's usually right but check what's printed on the wire to know for sure.

 

If it is 10 gauge, then the breaker is too big.

 

What should the breaker be for 10g wire — 30a?

 

Yes. 6 gauge for 50 amp

 

Present I made for a coworker who knows nothing about metal working hehehe.

 

Sounds like you are either not using enough stick out, or your feed speed is too low causing the wire to melt back into the tip.

 

A Rum chastity belt! Damn unique I must say.

 

Hobart Feed issue !!

When was the liner replaced last??

Your drive roll tension is way to tight when you have a burn back the drive rolls should slip

Just which wire are you using some can be garbage

Hub brake adjusted correct ??

Guide tubes and gun seated correct not sure if the 140 Has guide tubes

A burn back can be caused by a bad liner or cocking the gun to hard which causes the wire to stop causing your bird nest (correct term) then the wire burns back

If your changing tips you are using the correct size ??

 

Didnt realize that it wasnt required. Guess it was in the early 2000s most manufactures started color coding it from the little googling I just did.

 

Good list thanks!

The liner is the factory liner, it's a year old welder that I have ran maybe 30lbs of wire through and it has always done this.

I'll play with the tension.

I am using Lincoln flux core wire and the correct size tips.

I'll look into the hub brake, I don't think it has one but I'm not sure.

Guide tube? Where is that at?

 

Thanks I'll make some adjustments to my technique.

 

Question, I've 'inherited' a 90 amp Lincoln welder and have been told that using a quality spool would help. I've been practicing and scrap metal and the wire is almost out but I'm not sure where to get a new spool or what to get.

I need Flux self shielding wire. I don't plan to weld more than 1/8" steel.

 

If you don't have a local welding supply house, Lowes or Home Depo carry the smaller spools. Just make sure to take the roll off the bottom of the pile.

 

Is there a chance the polarity is switched? Flux core vs solid core with gas require the power leads to be switched.

 

Polarity is correct, it welds great, just sucks that once a session I have to change the tip out when it jams in the nozzle. I'll start with changing speed and stick out and go from there.

@mjp2 Prefer not to run sheilding gas as I like flux core, and running it on 115v I like the extra penetration that flux core gives.

 

Okay.

Have you ever used solid core with gas? I can remember the first time I was able to use the gas. Flux core was dead to me.

No more hot BB's going all over the place and so much quieter. My 1st welding machine was a 120 volt unit. The difference in penetration was negligible. The only advantage flux core has is you can weld outside and the wind wont affect you weld as much as with gas.

I won't use flux core in my shop. The BB's travel too far and I have a great fear of starting a fire. Those bastards are hot much longer than flux core BB's...and there is a lot more of them. I can weld wearing sandals. You can't do that with flux core

 

Any brand you recommend? I've been recommended Blue Demon.

$19 Blue Demon E71TGS X .030” X 2 LB MIG/GMAW Gasless Flux Core Carbon Steel Welding Wire, All Position, Easy Slag Removal, Formulated to Provide Porosity-Free, X-Ray Quality Welds

https://www.amazon.com/gp/product/B00F429RFI/ref=ox_sc_act_title_2?smid=ATVPDKIKX0DER&psc=1

But I like what I'm reading on Inetub wire:

$16 INETUB BA71TGS .030" on 2-Pound Spool Carbon Steel Gasless Flux Cored Welding Wire

https://www.amazon.com/BA71TGS-030-...=1514494825&sr=1-7&keywords=Gasless+Flux+Core

 

I know HD and Lowes carry Lincoln. use that.

 

You would weld with Sandals!!

I have been running hard wire or Dual Shield for to long to think about outside

Hard wire Run .023 and CO2 does better then self shielded

Do you know just what your doing when you burn back

always the same position

Your not over running the duty cycle and the machine stops feeding and output which would cause a burn back ??

Wire twisted on the spool that it seems to always happen could be every so many turns
