From my understanding carry too much metal will increase the risk of lack of fusion. Running too high voltage also gives lack of fusion as the arc is too spread out.
If you try to limit interpass temperature and to avoid hot cracking it also makes sense to run more passes instead of fewer and...
You have removed the "gas scale" that you talked about with a needle gun? That is what the small marks outside the weld are?
The only thing I can think of that this could be is that you are running fast and hot and don't have enough gas cover. So basically it's the same as mill scale but from...
I have the material yes, and I could sum it up for you. For what you are doing (welding mild steel) you don't need helium gasses, pulse, metal core wires or anything special. This type of welding has been done successfully for at least 40 years.
All you need to do is set the joint up properly...

Buy the mig welding robotic training to get the basics down. The author is very helpful and will answer questions you might have as well.
Just some wild guessing but from the sound of it you should most likely use spray and not pulse. Gas sounds...
I tried out the tig welder today using the buttons. It worked just as you guys said but man, there sure is a learning curve to it. Two buttons where each button has two directions, that's felt like it required way too much thinking. Wrong button or wrong direction is 75% likely to happen each...
It will probably work fine but not be ideal, less CO2 will make the weld have less energy. If you look at the specific wires used the manufacturer says what gas can be used with that wire. Recommendations I've seen are to keep CO2 15-25% rest Argon. Usually the dual shield wires for argon/CO2...
I don't know your application or why you want to do this, but you could also consider using dual shield flux core for similar applications as spray.
I know for sure people have been using it successfully on the 210MP.
Try something like Lincoln Outershield 71M in .035". I think you can get in...
The Lincoln engineers are correct. You are on the verge with that machine. Actually well under it - if you would use it for any type of production welding.
There is also the fact the characteristics of the machine (slope, inductance) doesn't fit with the requirements of spray transfer.
The...
Thanks guys, I'll give it a try on Monday. I've only used scratch start before and then it was with a CK torch with a gas valve so that's really the only torch I have experience with. It was very light and the hose very flexible.
OK, I think I get it now.
So you start the arc on the larger knob (rocking it backwards?) and it will ramp up automatically to the max. Then you can push the knob in the other direction and it will ramp down to the lower "crater fill" setting (selectable to % of max).
Then you can decide to...
So one of the switches is a rocker switch that changes the amps up and down? Has to be the one on the right then.
Or perhaps one button is for up and the other for down?
It's normal for the nozzle to get hot.
Binzel's MB15 is good for 60% duty cycle @ 150 Amp with argon/co2 mix. That seems to be more than what the Oxford 200-1 can deliver.
I've only done some scratch tig before so I'm at loss on how to use a tig torch with two buttons.
I understand that one button is for the arc but what does the other one do?
Has anyone used a torch like this?
BTW, from the color I gather it's Binzel torch of some kind. It's water cooled and it...
Globular transfer is physics so it is what it is. As you increase both wire feed and voltage you will get into globular at some point. I don't believe for a second that transformer or inverter will affect it in any way. But there are other things that will.
Going from pure CO2 to Argon / CO2...
The hiss comes from having the voltage set too high. You're looking for fast consistent buzz/crackling. Adjust the voltage until you have the fastest crackle sound.
I don't think it sounds like bacon that much actually so I think that is misleading.
You want it to sound like in this video...
