Yeah some manufacturers do that try Lincoln electric wire settings for what you are going after they provide better info

Neither one of our 0.023" wire settings above 2.5mm make any sense. No need to try welding. I'll check on 120V tomorrow to see if they change but it shouldn't make a difference.
I've emailed Yeswelder to see what they say.

Are your 0.023" wire settings for thicknesses less than 2.5 mm similar to what are in the chart that Yeswelder provided?

Thanks for your help

After looking at your data some more I realized I had my MIG and MAG mixed up. Your settings match mine after the correction. I wish they had called them C25 and CO2 since they are both MAG settings. They still don't make sense though. But I did check 120V vs 220V anyway. As expected, the settings don't change.

I guess the one thing working in my favor - I don't have a clue what the correct settings should be, so I'm going off cheat sheets for other manufacturers' welders that are posted on the internet as a starting point. I've never set my machine up using the metal thickness option - mostly amperage and then adjusting the voltage to the cheat sheet recommendation - then tweaking from there.

I didn't see what the values for less than 2.5mm material would be since 2.5 and up are so far off. This picture is 1/8" clean steel, using the .023 wire and 20CF/H C25 gas. The amps were 100 and the voltage 20.5. I went as high as 21.5V and down into the 19's - but the most pleasing "sizzle" was at 100/20.5. The only difference in these beads is I moved the torch faster on each successive pass:



Now the flip side. I googled "typical" settings for what I was doing and the consensus seemed to be huge: 31V / 125amps @ 437IPM wire speed. I wound up trying 135amps at 28.5V (135x3.5=WFS of 470ish?) and was getting beads like this:

I don't use the Thickness settings either. They seem too hot. I'm just concerned that if the Thickness logic is incorrect, what other problems are there?
I start with settings from cheat sheets that some other MIG-2015DS users made. I've uploaded them to the Google Drive folder in the link above.
Your settings are close to what Yeswelder recommends for the MIG-205DS. They recommend 108 amps and 21 volts for 0.118" thick material.

For 023 wire try adjusting from here starting 80 amps 250wfs an 18 volts

I've ordered a number of things that were shipped from China and 2 weeks is FAST, IMO. I wouldn't expect 2 weeks by any means nowadays with the flight limitations. I did once get some stuff in about a week and a half, but that doesn't happen anymore, and the Trade War with China can only be expected to get worse, IMO.

Just as an update to this thread... the roller I ordered from China/Taiwan June 4th arrived in the U.S. and was accepted June 10th... It's currently in the hands of USPS moving along it's route about 80 miles away.

Re: Welding Aluminum with MIG-205DS

I tried the 0.035" ER4043 wire using a 0.040" tip with encouraging results. The only setting that allows enough voltage range is the MAG 0.023" wire setting. I think the wire feed is a little fast for the amperage. I started with the setting recommended for Hobart Maxal 4043 0.035" wire of 130 amps and 24 volts for 1/8" thick material and played around from there. They recommend a wire feed sped of 400 ipm at those settings. I used voltage to keep in the appropriate range of spray transfer.
I could probably join a couple pieces of aluminum together if I had to but I need to do some more practice and refinement. I think I'm at the current limit of my skills. I'll probably focus on welding steel until I get more experience.

I ordered a knurled drive roller July 1 and it arrived last evening (July 13). I've learned a couple of things:

SpeedPAK shipping is an affiliate of Ebay. Choose the vendor who uses them! Their tracking reports are real, not made-up. They apparently fill an air transport pod and send one over, every couple of days. In contrast my experience with 'Economy shipping' has been poor.

Ebay seller chnsalescom seems to specialize in welding accessories and actually stocks what they sell. I see they have 100% positive feedback which is rare among China vendors.

That is in contrast to many other sellers, who drop-ship, ie accept your order then have the real vendor send it to you. If your industrial stuff is listed among womens clothing and doo-dads that's probably a drop-shipper. Reading the seller's feedback to see what else he's selling can be a clue to whether he understands the product.

I just ordered one up yesterday - expected mid August. Fingers crossed.

There are some decent Chinese vendors out there if you can find them...

Followup - I tried out the new knurled drive roller for flux core yesterday and its day/night better than what was in the welder. Prior owner had modded this Harbor Freight MIG-180 as a hobby project. It was immaculate and appeared never-used. A big capacitor mounted external, a longer stinger, and a relay to power the drive motor instead of its current going through the motherboard. Then after he moved up to a better welder he sold this one to me - $25! But it didn't feed smoothly when I bought it. I suspect that was his reason for adding the relay feeding the drive motor.

I don't know if the feed roller in it was a useless one from some other project, or it was the original. (.023 + .030 and slightly knurled, while I thought .030 + .035 was the original spec). This new knurled .030 + .035 roller feeds flux core flawlessly with very little pressure compressing the wire against the roller. I think distorted wire explained the previous erratic feeding. Problem solved for $5.

Would you happen to know if you can set the amperage below 80 on Gasless? I'm unable to, and am having to play with voltage it seems to adjust anything. I'm new to MIG and just learning this machine with still have a way to go but I have a lot of spatter and understand that has to do with the arc distance which seems to be controlled by wire speed which, with the yeswelder, seems to be controlled by the amperage?... I'm welding 16 gauge steel tubing using Blue Demon E71TGS .030 with still a way to experiment but it seems voltage is my only means of heat control at the lower settings?

My 205DS doesn't go below 80 amps on gasless either. The wire feed speed is directly tied to amperage for a specific setting (as far as I can tell) and you can't control them independently. That is the problem with the synergic settings. Similar to what I was doing for aluminum, you could try to find a setting for the combination of wire feed speed and amperage that would suit your need and tell the machine that you are using that wire diameter and gas. I don't think it will matter that you aren't actually using gas. I added a graph (all settings graphed) that combines all 6 combinations of wire feed speeds and amperages to the spreadsheet in the link below:
https://drive.google.com/drive/folde...sk?usp=sharing

Looking at the recommended settings from Yeswelder, the wire feed speed for 0.035" gasless wire is 5 m/min (197 ipm) at 80 amps. From the graph, that is very close to what you get when using the 0.035" MAG setting. Since you are using 0.030" flux wire I'd set the machine to the 0.030" MAG setting and start from there with what you think the amperage and voltage should be.

I sent Yeswelder a suggestion that they have a setting that allows independent control of wire feed speed if they make an updated version of the MIG-205DS. I also suggested that a synergic setting for aluminum would be more useful than the CO2 synergic setting (Does anyone use CO2 with this welder?).

 

[RKCRLR]

Also, the only wire diameter option for the gasless setting is 0.035". So the 0.030 flux core wire is probably being fed too slow for the amperage.
Do you have some 0.035 flux core wire to try? According to the Yeswelder settings you should be able to use 0.035 flux core wire on 16 gauge metal.

 

[jerlands]

I'll try playing with gasless on gas settings and see if I can do that... seems like a good idea anyway unless there's some kind of pressure switch. Right now I'm set at 80 amps and 17.1 or so volts. I'm able to get the penetration and weld profile I'm looking for but it's too hot to run a bead. If I run lower volts the weld tends to become to high and rounded so what I'm doing is "stitching" the weld across, 5 seconds on - couple seconds off, and that is doing the job. I've never used MIG/MAG but I can see how the gas would provide cooling so there can be less stickout. I could pick up .035" wire and may do that but I think the idea of using MAG settings I'll try first. And, was there a reason for choosing MAG over MIG?

 

[RKCRLR]

And, was there a reason for choosing MAG over MIG?

You're using 0.030" flux core but there is only a setting for 0.035" gasless so your wire is likely feeding too slow for the associated amperage. Per the chart provided by Yeswelder, the wire feed speed for 0.035" gasless wire is 5 m/min (197 ipm) at 80 amps. From the graph in the spreadsheet, that is very close to what you get when using the 0.035" MAG setting. That implies that the synergic settings for MAG and Gasless are similar so if you're using 0.030 flux core wire then the 0.030 MAG setting would be a good starting point.
This assumes that the values in the chart provided by Yeswelder are correct.
If you know what amperage, wire feed speed, and voltage you want to use go to the graph in the spreadsheet to pick a wire feed speed and amperage that is close. Then see if that setting will allow you to choose a voltage offset that is in range of what you are looking for.

 

[jerlands]

It worked!... the MAG setting that is for flux core... I would have thought a pressure switch would have prevented running without gas?... anyway... I'm way down to about 50 amps at 16 volts and I am getting good penetration and the bead is laying down fairly nicely... best of all... very little spatter... so thanks for that suggestion cause I don't know if I would ever have headed that way...

I just ordered one up yesterday - expected mid August. Fingers crossed.

Just got the roller in the mail, little over two weeks isn't bad at all. Except the knob on the tension wheel adjuster broke while I was putting it in...Aaaargh, just sent a note to YesWelder to get a replacement.

YesWelder's customer service is a crack up. I emailed that I needed the new wire feed tension knob, sent a pic of the part and the SN/receipt. Got pretty quick replies and a shipping confirmation. Arrived yesterday (yes, Sunday) via DHL from Dubai(???) wrapped and packed like it was a Faberge egg lol. There was a hand written apology/thank you note in the package to boot. The machine's kind of a pain/tricky to set up properly (I'm getting there) but can't fault them so far with standing behind it.

Hi, I am a new member here
I have a 205DS, and I am intrigued by the SLOOW wire speed it gets.
For example on MIG/CO2 at 205AMP I am measuring about 80IPM. This feels very low to me, and also relative to the graphs you guys posted.

Can someone measure theirs and post back the measured speed? I am wondering if I got a defective unit.

 

[Munkul]

Is it not slow run-in?

You'll never generate 200 amps with 80ipm wire. It's physically impossible.

 

[Shootr]

What wire size are you using? I take it you have that set properly on the machine? I only have a 30amp circuit so mine tops out at 160amps +/- so I can't get you a comparable measurement.
