Vertical up!

admin

When mig welding in the vertical up position what adjustments should be made to avoid the weld looking like a turkey's neck.  Amprage?  Wire speed?  Technique?  Travel speed?
Reply:The first thing I would try would be dropping the voltage down  which will make your weld puddle less fluid and easier to control.  This should require an increase in the wire speed.Drop the gun angle. Drop it about 10 to 15 degrees off 90 degrees from you work peice. So for vertical up you want to be pushing the weld puddle.
Reply:I agree with the answer Scott gave you. You have absolutely got to get to where you can read the puddle well before this happens right. Also, try doing a small weave to keep from stacking up.Lean mean TIG weldin' machineSquarewave 175
Reply:I dissagree with Scott. For T9 wire in flat and horizontal i use about 25 volts @ 250 inches per minute wfs and for vert up i use about 23.5 volts @ about 170 inches per minute wfs. For T11 in flat and horizontal i use about 18.3 volts @ 150 wfs and for vert up i use about 16.3 volts @ 100wfs. For S6 in flat and horizontal i use about 20.5 volts @ 225wfs and for vert up i use 19 volts @ 175 wfs. This is all on 3/8 inch and up thick steel.
Reply:I think gf's answer makes sense I decrease wire speed a little when running up hill and tilt my gun back to flatten out the bead the higher on the the vertical surface the more I tilt so that by the end of the bead I end up with less than a 45 degree angle with my material. With steel I use a sorta J motion running ahead of the puddle then back with aluminum I just run small circles all the way up. I can not tell you what exact voltage or wire speed I use the numbers 1-10 on my profax spool gun have long since worn off.
Reply:I vaguely remember in my seabee SW 3/2 manual it recommended something along the lines of 10% drop in amperage for out of position welding as opposed to flat position.  As I understand it, your wire speed is your heat with mig.  Therefore, by lowering your wirespeed you will lower the amperes you are using.   Not sure Id go as far to say its 10% drop in wire speed for out of position as from flat, but perhaps.  Anyway, my experience first hand has been to drop the wire speed a tad. If its giving you hell you might drop your voltage a pinch and see how that works.  But as I mentioned I beleive its primarily an issue with your wirespeed.just my two cents for the day.CHRIS
