cant get this down for ****.I dont know what the problem is but i have been doing a zig zag motion pausing on the left, jumping across the center then pausing on the right. looks like **** and doesnt look strong. im also doing something wrong, my puddle will be going fine the all of sudden its like the wire stops melting and skips like zap zap zap zap. dont know how to explain it but its frustrating. maybe welding isnt for me.
Reply:The zap zap zap is when the wire stopped feeding. Check the usual things, tension rollers etc. Until you get it feeding 100% consistently you'll never get it to work right.As for vertical up, if you want it too look good, turn up the volts and go down - run a stringer. If you want good penetration, run up.As for the gun motion, the problem is with vertical up your are essentially in the heat. Heat rises and so is the welding. Try something like an upside down 'U' or 'V' instead. You still want to keep the wire in the puddle. You are essentially tracing the puddle edge. If you step consistently you will get a pattern going all the way up.The web site weldingtipsandtricks.com has a video welding vertically up.Con Fuse!Miller Dynasty 350Millermatic 350P-Spoolmatic 30AMiller Multimatic 200Hypertherm PowerMax 1000G3Miller Maxstar 200DX
Reply:yea i've watched that video and tried the technique. but i just realized my wfs wasnt near as fast as the video, maybe that will help? could the welding leads being kinked cause the wire to stop feeding?

Reply:alright, tomorrow i will turn my voltage way up and my wfs way up too, i was around 17 volts and 175 wfs.on a lincoln powermig

Reply:Make sure you keep your tip to workpiece distance constant, it's very important.probably around 3/4 inch but don't quote me on that.I've burnt so much stick these last 5 years I have lost a lot of my wire skills.
Reply:When people are having issues with vertical, I usually find it's because they really are not seeing the puddle. Just went thru this with a guy at the tech school. He got away with timing his motions doing flat and horizontal, but that didn't work on vertical. He never got the edges to fill, and if he did he had too much in the center. Once he had that "AH HA!" moment and actually started to see the puddle rather than the arc things started to fall into place. Your machine settings sound pretty close to what we were running on the XMT for his verticals. Picts of your welds would help diagnose some of your issues..No government ever voluntarily reduces itself in size. Government programs, once launched, never disappear.

Reply:It can sometimes be common to experience arc outages when welding out of position with too little current, or too much of a standoff. Arc outages are an annoying "pop pop pop", and the wire seems to be stubbing into the parent metal.The puddle will drown the arc, kind of like water drowning fire.Try to concentrate on keeping the nozzle close into the steel with minimum stickout. As stickout decreases, amps increase. Increased amps mean fewer outages. It's almost like stick welding...........shove it in there"Any day above ground is a good day"http://www.farmersamm.com/

Reply:Originally Posted by i4sillypwryeah thats an entirely different ball game dude and it in no way relates to running solid wire up hill. vertical up with .045 dualshield is hands down the easiest vert up weld i've ever done. OP why are you trying to go uphill? if you've just started welding concentrate on welding flat first. You'll actually impede your progress by trying to learn the harder techniques first and it will frustrate you.

Reply:When you are going up, make sure you are moving the whole gun up and not just moving the tip upward. watching the puddle is extremely important, when you do a regular weld going uphill it looks tall and like its falling away. When you do the weave basically you put one of those on the right then go make one on the left, the difference is that you are basically filling in the sides of one tall weld and making two instead that fill the void. When watching the puddle you can see the creation of one and then move to other side and fill that in then go up on top of the other side again and just basically keep stacking them. I find a straight in angle works best for me so that I can see the whole puddle not just the top since you need to see it fill in on the bottom. Counting can help but it usually changes as you go up and heat builds. sorry if that was a little wordyMillermatic 252Lincoln 175 plusTA 185tswTA 161stlhypertherm pmax 45Victor torchHenrob torchAn S10 for each day of the week |
