In this video, I am manufacturing some 10' long columns from 6x6x3/16 tubing with 10"x10" bases. This is all welded with the HTP Pro Pulse 300 and .045 dual shield flux cored wire with 75/25 gas. Excellent puddle control and no spatter.
I dont think its a dumb question The short answer is no. The medium length answer is: Flux cored wires are typically not welded in pulse mode, solid wires and metal cored wires can and will be occasionally welded in pulse mode.
amzn.to/2zmeSDH this is the helmet amzn.to/2ucKxBT this is the passive filter ... OWW when i looked at the price ... i bought those for $15 8 years ago ... now they are 50 !!! but those are VERY good - real glass - even tint - i LOVE them ....
a good 5/16 single pass. - maybe more - but at some point, you should go multi-pass to not sacrifice joint integrity ... I welded 3/4" or 1" with it. ... no much though .... over temp may become an issue at some point ...
Would you recommend .045 wire or ok with .035 dual shield doing three pass stringers on the iron mig 221p? I did an etch test with the .035 wire with 90/10 gas on a 16mm x 8mm T section as a test piece to check it before I attack the job. I think the penetration into the 16mm is very marginal. It got it but no penetration in the etch test. I have 100% c02 gas I just need to setup the reg and lines and will retry the test on that. Do you think with the 100%c02 with .035 wire it will be better or should I just step up to the .045 100%c02 and just put up with the likely duty cycle issues for this one off job?
Skylinerd1 do you mean 045 dual shield over 035 dual shield? On the 200 definitely not. It is possible to run 045 dual shield at very low settings - i have done it a few times. It works ok - but not for long till you run out of duty cycle or you accidentally hold the gun a little bit too close and spike over 200 amps and the machine detunes itself. 035 dual shield works great in the pp200. Lincoln outershield 71m or esab 7100 ultra are my personal favorites. And yes you have to do multiple passes and when i did it i used 75/25 gas. You need to pay attention to what your wire is rated at ( as far as shielding gas ) Very few wires only can be run with 90/10 gas. Typically argon mixtures give you a hotter arc than just 100% co2, ( mire spray than globular) they also give you better properties ( tensile strength etc) in the weld joint. Also between 100% co2 and 75/25 are typically several volt (3 ish) difference at the same wire feed rate. Since the program in the machine is made for 75/25 and not 90/10 or 100% co2 you need to make voltage adjustments to accommodate using a different gas. Failure to do so will result in poor weld quality.
Iv noticed a couple of times now the machine detune itself on an arc strike with it not even turned up all the way maybe at 3/4 or slightly more. Turned it back to the setting I had it on and it was fine. Just a quirk of how they've designed the machine to stop it offing itself or something? Yeah I figured id have to turn the voltage up more with the full c02 gas... hmm will have to look into getting a bottle of 75/25 which is a bit of a pain actually. I also notice in the synergetic program for dual shield on the 9.0mm setting (max for that program) the voltage is up at 28+ volts when everyone seems to recommend between 22.5 and 26 or so volts for this wire and I felt 24v and 440ipm was pretty good in my test. Its best just to stick within the wire manufacturers recommended settings or go with the synergetic program for this thick material? Id didnt see any diff in penetration with the 28v setting.
Pardon my ignorance but you say you're running gas and flux core at the same time? I'm a little unfamiliar with Mig... I thought you don't need the gas if you're running flux core? Is there an advantage to using both?
this is flux cored gas shielded, commonly referred to as gas shielded flux cored, dual shield, outer shield .... it uses 75/25 gas and it is run on DCEP (same polarity as "regular" mig) and yes - there is an advantage - there is increased ductility and elongation in the welds, the welds are not as hard to grind as "regular mig" , no spatter, deeper penetration, better and easier to run out of position, no spatter .... the list goes on and on .... of course, it cost a little more money too... this is typically used for heavy equipment manufacturing and repair ..
@@ZILAwelds And according to the wire manufacture, this wire handles dirty, greasy, rusty or painted steel very well. They say it needs virtually no cleaning to get good welds from it. And it's much more forgiving to having some of your shielding gas blown away when working outside in the wind.
I was wondering cause I actually looked them up awhile ago and that was pretty much the only way to get them but I thought maybe they had a US distributor
Stel does have a US distributor ... its called HTP. HTP is a private label distributor. Stel has distributors who sell Stel brand and they have multiple distributors in multiple countries who sell the machines under a different brand name (private label) .... And Stel likes it that way - don't ask me how or why ...? no clue
I welded with a few 350p's they are a solid machine - a little cumbersome to dial in - plenty of power !!!! but to "only" have single pulse is a "big" downfall once you welded double pulse ... what do you want to weld? steel? aluminum? how much? how thick? are you ever bringing the welder anywhere or it never leaves you shop? the 350p is like the "perfect" production machine for a guy who builds trailers or aluminum boats ... etc .... put a push-pull gun on and get rolling ... I know guys who bought that setup to fix aluminum dump trucks all day ...
because gas shielded flux cored is soooo much better - better weld - better elongation and ductility, nicer beads, less smoke .... and even if this was all just in my head .... there are ford and chevy guys there are automatic and manual trans mission guys ... gas and diesel ... and i am a gas shielded flux cored guy vs a gases kind of guy
ZILA ok fair enough, but are you saying solid wire would not do this job? It may be better but is it necessary for this job, isn’t it a lot more expensive? Also, I have a plasma table with a powermax 105, are you happy with the cut quality of you 65? I have to cut about 3mm larger than bolt size to have enough clearance and cut edge straightness is hard to control. Could you show some close ups of those base plates for example?
A J solid wire would absolutely do the job! And yes the flux cored is more $ but I really like the way it welds and also its faster, less clean up, lays a bigger single pass weld and i “sold” it to the customers as superior to what he used to have ( which is a regular hardwire weld ....) Aa far as the plasma: The 65 is doing ok for me. I have an 85 also but never run the 85 on the table for 2 reasons: 1) it has a solenoid issue and firing reliability issues ... ( a lot of ht machines have that! The ht rep said: there is nothing wrong with your machine - it works, it cuts but if you want do do something about the random firing delay .... there is this 300 dollar solenoid update kit ....) So needs less to say - i am not like other channels bashing all my tools here .... but if you see in the near future some plasma changes .... don’t be surprised .... 2) the 85 would max out the electrical system in the building the table is in or i would have to run it off a generator .... i dont like either thought 3) i typically dont cut anything heavier than 1/2” .... i dont stock plate heavier than 1/2” i dont want to lift it, but it etc .... i can just send the dxf file to my vendor and i will be fine !!! I found that for my business there is a huge advantage to be able to make my own parts and plasma cut and prototype everything up to 1/2” at a moments notice - i also found out that at the price i am charged buying it cut - its not worth it for me to handle anything above 1/2” .... that 5/8” plate was a left over from a rush job i did a while back where i had to replace a 16mm plate in a german tub grinder in a paper shredding plant ..... and once a year i cut something very small 3/4” occasionally ... for my buddy with the machine shop if he needs it “now” As far has hole size: I have pretty sophisticated path rules .... I have to program about .030-.040 over on the diameter to be on size ( since on heavier material i see about .015-.020 taper in a circle like that) Make sure your torch cuts at the right height ( since the flame is bulged and that creates taper also) and also make sure that your cut speed in those small shapes slows WAY down .... And of course - super dry air, at the correct pressure and “fresh” consumables and you’ll be good to go ... you should not have to program 1/8” over .... i heard a lot of stories about the 105 though .... what amperage consumables are you using and what material thickness are you cutting? How is the wiring to the cutter? How long, what awg? What voltage?
hot weld on this particular job it would have been allowed - but i do a lot of similar jobs where it isn’t allowed and since i have the machine and consumables to do it right - i might as well
What's the difference between flux core,? And gas shielded flux core wire..?Why do you need the gas when you can use the the flux core with no gas..?is that not the whole idea of the flux core wire not having to use gas with it...nice if you can explain or show me..?...thanks.
flux cored wire is tubular wire with flux in the core. that is all there is to it .... and there are one thousand different kinds. there are self shielded wires (gas less) they are typically labeled shelf shielded or inner shield and those come in different diameters, most of them are welded DCEN. Some are only good for single pass, others are multi pass some to a certain thickness others to unlimited thickness. they come in mild steel, low and high alloy, stainless, hard sufficing ..... and there are gas shielded flux cored wires. typically those say outer shield or dual shield on the package .... those are usually welded in DCEP and are either welded with CO2 or a blend of CO2 and Argon. In this case I used 75/25 gas - you need to make sure the wire you are using is suitable for the gas you are using. also those wire come in mild steel, low and high alloy, stainless all different graces and hard surfacing all different kinds .... the bead appearance and strength is typically better with gas shielded wires. all of them (all joining wires not necessarily hard surfacing wires with gas) are rated multi pass, unlimited thickness ... this is a science. - it is more complicated .......
