Auto dimming mask question

[Jasonz172]

The stick out and standoff height is actually too long. You should have about a credit card thickness under the tungsten between it and the metal. The stickout should be 1/4" or less. One thing is possible: that you were varying your arc length (with such a long one), tricking the helmet into thinking the arc was going out.

I didn't try this yet, but I did try adding some pulse to the arc, and I think it helps the mask stay on. Still some funny stuff going on with some flicker, but I just don't think i have the pulse set properly or something. Need to get more experience with everything. I had no idea about the credit card thickness thing, I imagine that would really help me control the pool better but so far I've been paranoid about dipping my tungsten into the metal. I will have to give it a try tomorrow.

Thanks

Don't worry about dipping the tungsten, it will happen a lot while you are learning. Just keep plenty of sharp ones at the ready so you don't have to stop and grind all the time. Sharpen both ends if you can live without the color coding. Just remember to get the tungsten out of the puddle BEFORE you back off of the pedal/switch. (As usual, don't ask me how I know)

I agree with Mark, check that the stick-out out less than 1/4", arc length short, helmet in tight (maybe turn your head to the side more to expose the sensors and see if there is a change). Also try different angles on the torch more towards vertical and see of that helps. You have nothing above that would be blocking the sensors on the lens right? Like working around a vertical piece.
