I need some advice I am doing pretty good with the new precision tig 225 and only have this problem once in a while. When I add filler it wants to stick sometimes It comes out but it screws my timing all up. What causes this and how can it be prevented. I also just started trying out the pulser as I wanted to learn without it but I have the issue both ways.ThanksDonnelly Small Engine & WeldingFoley AlabamaLincoln 225 TigLinoln 215 migHypertherm Powermax 65Ellis 1600 sawEllis 6000 belt grinderJD2 Model 4 tubing benderAtlas 12"X54" metal latheLots of large hammers
Reply:Puddle too small for wire, wire too big for puddle, wire position too far outside puddle?With a small puddle and a tight arc lenght, it can be diffifult to get the wire into the puddle without hitting the tungsten or maybe sticking as you say. Although a tight arc is best for a controllable/concentrated arc, if you have trouble getting the wire in the puddle, you could run a longer arc and kick up the current. Also, holding the torch directly perpendicular to the joint helps arc concentration/control, but tilting the torch slightly to push the puddle out front a bit helps give access to get the wire in the puddle.
Reply:Pulser pretty much said it. I used to have that problem and sometimes still do. Its when the filler is out of the gas pocket. I still stick the filler to the base on vertical up. Maybe a bigger gas cup.Bracing the hand with the filler in it helps.David Real world weldin. When I grow up I want to be a tig weldor.
Reply:You need to get the non-sticky type filler...it always happens with the sticky filler. Pulse man hit the nail on the head.John - fabricator extraordinaire, car nut!- bleeding Miller blue! http://www.weldfabzone.com
Reply:Thanks for the replys I turned off the pulser and it was much better I will just have to get used to the pulser in the future.

Reply:Sticking when you're pulsing is just a matter of technique. You said that you were starting to experiment with it. You have to just work on it. Get some plate to practice on, start with a relatively low pulse frequency, set your pulser to 75-80 percent high value with about 60 percent background. Having a higher background for less time decreases the probability that you'll stick. What you need to do is feed the rod when the power is high, and retract just before it pulses to background. With a low pulse rate, it is easier to get the muscle memory of dabbing the rod. As you get the rythym, increase the pulse frequency, set your power to 60 percent ontime with 40% background, (backgound would be 40% of high value for 40% of the cycle) and go to town.You'll get the hang of it.I r 2 a perfessional
Reply:I have had the same problem. I found out it was because I was dipping to close to the edge of the puddle. Tilt the torch back a bit to make the puddle extend forward more and be sure you have enough heat. You may also be moving too fast.. Try dipping into the top edge of the puddle where it is melted and not the base edge of the puddle where it starts to melt.If it does stick, don't let it through you off. Stop moving the torch and get the filler out and start again.Build a Barstool Racer at BarFlyRacers.com! |
