Welding Tips and Tricks

I was reading a thread about a Hobart 125 mig. After reading this posed a question.

With proper fit up and multiple passes can one weld 1/4" metal with a 100 amp mig???

Preheat it RED HOT with a cutting torch, vertical uphill with a gap.

Maybe....

What difference does it make???

Haven't you been around these forums long enough to know???

Gee's...

Just use your Thermal Arc 211.

Maxed out.

Can one weld it, yes. Should one weld it, well....
First going off of Millers weld calculator as a reference, solid wire suggestion is 200-210 amps. Self shield Flux-core is 170-190.
The first question I would ask myself if I were considering this is what is it used for and what joint configuration it is in? IF you were to use this machine for 1/4" in a T joint configuration, I would bevel the plate and put in a good root pass, followed with as many passed as it took to achieve a true 1/4" fillet weld. Pre-heat may be necessary as well.
This machine actually says it puts out 125 amps and is rated for 3/16" max. Hope this answers your question.

Try it and post the results.

More interesting than asking a question well known for causing arguments on welding websites.

Who's not playing nice?
This horse has been beat over and over.
I've tested welds.

The next one of these threads that someone posts, I'll let someone else handle it.

I'm sick of 6013 and 115 migs.

I've been fabricating trailers to haul coils outta US Steel Gary using my 115V flux core for six months now(those Russian guys always buy everything I can make, but how they complain about the price!) I've started getting checks in the mail from local towing companies. Says it's "commission" for "all the business I've created for them."

Anybody else ever had this happen to them?

Sarcasm BTW

Ken,
Why are you using that welder?
Use a big machine.

Read it again, my friend. I might have made it too subtle for those not in the industry.

Coils. 10k-45k+ lbs each


Eastern Euro(Russian) trucks drivers are notorious; both for being extremely cheap, and doing all kinds of hinky things.

I don't own a 115v MIG. On the occasions I weld on trailers, it's generally 6010 burning through layers of rusty, greasy crap. S/F....Ken M

Looks like some pretty thin stuff.

Sorry bout that.

~John

It might look thin - but that coil would make an impression if you were driving near the truck it fell off ! or were they filming another " Final Destination " film ? hated the last couple - but the one with the log truck looked very real & scary.

Those coils weigh 20k+ in steel, 10K in aluminum. 40+K coils are common. May as well be a solid piece of steel for impact purposes.

They destroy stuff all the time. Been a couple cases where foolish truck drivers stop on RR tracks and the train hits the coil. Last one I remember killed 7 people.

If there was somebody putting together trailers hauling coils with 115v MIG, everybody would be out to get that guy, from the USG to the Mob. S/F....Ken M
