clogged

admin

Hey all. I have a HH175 running .035 wire. I seem to be getting alot of spatter. Any ideas on the fix? I dont remember having this issue with .030 wire. I'll post pictures of before and after below.axehind

Reply:The short bead I ran. I stopped once and restarted. I put the gun there for size reference. Attached Images
Reply:After the bead. Doesnt the nozzle have to much spatter in it for the length bead I ran? I dont remember it being like this before Attached Images
Reply:What material thickness are you welding on? What are your machine settings for this thickness with the .030 and the .035?The ball on the end of your wire is pretty large, which indicates to me that you are running to low of a wire speed setting for the voltage tap. Or you could be running too high of a voltage tap for the wire speed setting needed. Answer my first set of questions and I should be able to  help you some with tuning the machine in a little better.ESAB Migmaster 250 Hobart Ironman 230Multimatic 215TWECO Fabricator 181i & 211iHH125EZ - nice little fluxcore only unitMaxstar 150 STH - very nice
Reply:The material was 3/16 inch on Tap #4. Wire speed setting is around 85. I had the wire speed lower (75) but I kept getting a clogged tip.axehind
Reply:Voltage tap #4 outputs too high of a load voltage for 3/16". Use tap #3 and try the wirespeed set around 60 to 65 as a starting point.ESAB Migmaster 250 Hobart Ironman 230Multimatic 215TWECO Fabricator 181i & 211iHH125EZ - nice little fluxcore only unitMaxstar 150 STH - very nice
Reply:It keeps buring back up into the tip. I'm going to check the feeding to make sure it's not slipping at all.axehind

Reply:hmmmm....I have the same machine and to make a long story short....try:1.  increasing stickout to about 1/2 inch at high voltage settings.2. replace the hh175 crappy factory ground clamp with something that will work.3. drop the wire speed to 45 - 604.  the nozzle will need cleaning about every pound of wire if you're using flux.  it' just the way it is.5.  if the stickout get too short, the eventual burnback will slow down the wire speed due to internal tip clogging.  the tip will eventually clog and go bad.  it doesn't take many mishaps with too short of a stickout to fry a tip.6.  if you're an old hand at stick welding, the tedency is to shorten the stickout on mig since the old habit of chasing a stick electrode is cooked into the brain.  7.  make sure to keep the gun lead as str8 as possible to ensure smooth wire feed.A true democracy is two wolves and a sheep voting on what's for lunch.
Reply:and one other...if you angle the gun to the work too much, the stickout that you thought was 1/2 inch is really much less since the arc will climb the wire and melt it closer to the tip.and you get more spatter into the gun tip.A true democracy is two wolves and a sheep voting on what's for lunch.
Reply:Thanks for your help guys. It was the tension that was messed up. All is running better now.axehind
