questions from a new guy

Postby Scott Morris » Thu Mar 30, 2017 11:01 am

Have always wanted to learn to weld. Bought a Lincoln Pro Mig 180 running on 220v. The cylinder is 75/25. I have attached some pics to show where I am at. Please try not to laugh too hard, it took me a while just to get to this point. I seem to reached a plateau and not improving. Hoping someone or lots of someone's could help go over this hurdle to keep getting better. I am using .020 wire, holding the gun 90º to the weld. Have tried different cursive techniques. These particular welds were made with a setting of 5 on the wire speed and D on the volts for those familiar with the Lincoln 180. Have tried all different settings including those shown on the chart in the welder. This has produced the best welds so far on this particular metal....

Is that steel filler metal that you are using?

I've never seen anything like that.

I would check the spool. That actually looks like aluminum.

Otherwise, it would be the usual suspects. Correct polarity, adequate shield gas, etc.

The polarity is correct, 75/25 in the bottle, Mild steel Mig wire L56...... spool is free just a very, very slight amount of drag.


Thanks

These types of things are usually best addressed in person. Sorry I couldn't be of any help to you.

Good luck.

Wow..that's a mess. Your metal looks really dirty and that might be part of your problem but I have only seen spatter that bad with flux core...something else is wrong.

Just things to try that might do something and double/triple check everything.
