Teach us how to weld

[a_kelley]

for your vertical, try 2 pieces of 1/4 or 3/8 plate. bevel one then tack weld the two together with about 1/8" gap between them. Stand them vertical then weld your uphill weld.

I'll do it tomorrow.. I've got 3/16 FB laying around.. too bad I got .030fc instead of .035... Still 1/8" Gap or should I make it 3/32"? It's just a hf Chinesium 90a 110 wire melter I've had for at least ten years.. I guess I can throw it in the 12 ton press too when I'm done..

Here’s vertical inside corner flux core on 3/16, picking up some hrew tom so I can get the angle change practice in! I’ll hopefully have a order going in for a few sticks of tube tom and see what all he can get for me!

Vertical open root flux core 1/8”ish gap 0.30 wire I got lots to learn...!

 

[C.Berry]

Try it on flat plate, make a 90* and weld uphill. It's almost similar to tube, except it's not wrapped around a circle. Perfect that first, then try flat, and inverted. Or whatever order. Basically tube to flat will be very similar, though over a constantly changing angle. Simplify, then complexify. That's my 2 lb of scrap steel contribution... That might be about 12 ¢.

This just clicked... smdh I now see what your saying with 90* on flat plate! My mind is on overload lol

Not to horribly bad for a first time. I thought you were gonna stick it. But since your using flux core, come out of the root more and let the puddle flow out. blend the material of the unground side help fill the open root and the bevel side. uphill welds will need to be wider then a flat so the weld can "stack"

here is a vertical I did on a track loader last saturday. Was a crack in 3/8" formed plate. I ground the crack completely through then welded. Could not get a drill in to end the crack.

You can do 3/32, come out of the root and stack it. Remember to stop and let the machine cool too..

@Jeff B here was my stick attempt man pretty horrible my gap may be smidge bigger than 1/8 but no excuse lol

I’m going to do another stick test tonight if possible my first one was a disaster!

 

[a_kelley]

I forgot to bevel the plate.. oh well. It is .172 thick, root Gap 3/32.

I didn't start low enough into it and quit before the top.. it shows when I threw it in the press.. y'all tell me if that's decent or not for someone not professionally trained or certified..

 

[C.Berry]

Made a third arm out of some tube I had off old links turned out pretty sweet needed the 220 power but it’s not gonna hold anything up but scrap metal lol

 

[C.Berry]

Ok so real talk I know a lot of people don’t like flux core bc of spatter and smoke but in my situation where my entire rig will be build outside majority of work in wintering time, is flux core ok just not desired? I get great penetration on 3/16 plate and thicker even on 110v at 20v! Just curious bc I was gonna go pick up a gas cylinder but would rather spend the $300 on fuel system..

 

[C.Berry]

And fluxcore is the stick of mig welding... so it’s kickass imo lol

Will your machine run dual shield wire?

[a_kelley]

Flux core is good for penetration from what I understand. I don't remember the why though.

 

[Jeff B]

You will be fine, just clean, check and do a good job.

It's not like you're John fuller..

Not that I’m aware only flux core setting is no gas required!

 

[C.Berry]

Wow I see now why gas is used... pretty but without 220v I feel like it’s not penetrating 3/16 like flux core with max wire speed or I may have been over heating with flux lol I’ll figure it out reading and reading some more gonna order etching acid/gel to cut polish and inspect weld penetration on my scrap pieces, I know puddle control with gas is way better and arc is controlled a lot easier also! I’ll probably use all processes of welding on my rig except tig bc ain’t nobody got time or money to be that pretty on a rusted mule! Appreciate the tips I’ll possiblt post something up in weld porn thread one day!!

You can get by with white vinegar instead of etching acid Naval jelly also works, nut I just use vinegar. Cut and give it a decent polish, then apply vinegar with a q-tip. Takes a minute, but it'll show you what you want to see.

Awesome thanks

As mentioned I’m no mig welder, I’m no welder period but I can fake it to make it so to speak, I’ve had farm equipment repairs on bucket arms hold up for years from when I first started arc welding! So is mig welds with gas suppose to not be flatter? Lol or what am I doing incorrect here? Flux core doesn’t seem to sit on top of the metal as much

settings are tough rock dial in on mig for me right now but getting better I’m running 15cfm gas is that enough in little shop no wind doors open? These also are all on 120v plug not big plug bc I’ve yet to add a breaker to the house

Check polarity, it's reversed for mig with gas from flux core

This machine pretty much sets itself up in that sense I just move dinse connectors for eac process! Clamp negative guns positive! I’ve found if I trick machine to think I’m running 0.25 wire I can tur. My speed up going to try and see how that does!

 

[a_kelley]

Does the book that came with the unit not have recommendations on gas flow rate and wire speed settings?

 

[C.Berry]

It auto sets it but I’m welding on 3/16 plate while in 110v plug so it won’t allow more voltage and wire speed only goes up to 10gauge metal thickness on 110 with c25 and wire speed stops at 290ish! I just found mig with gas isn’t like flux mig that wire speed isn’t penetration lmao just lumps

 

[C.Berry]

It says 30cfm wtf lol I’m being skimpy with my gas I reckon ill adapt and overcome! Need to learn more from actual welders I suppose, hands on is way better than videos lol
