Spatter and contact tips.

admin

I have a millermatic 211 and have noticed a lot of spatter. I tried to dial in the machine and I even used auto set. Still getting it. I'm using 0.030 Hobart and Lincoln of the same size. Er70-s6 solid wire? 1/4 inch or 1/8 inch but more so with the 1/4 inch. The settings that I'm using for 1/4 inch ws at 90 and volts at 6 on the dial. I changed contact tips with little help. Any help is very appreciated. Also how often should I be changing tips? How will I know when it's time to change contact tips.
Reply:Settings sound roughly correct. Excessive spatter could from several things. Poor gun angle or excessive stick out comes to mind right away as two of the big ones. Picts usually help.As far as the tips, most times we change them out when students weld the wire to the tip long before they ever wear out the tips. I seriously doubt the average hobbyist would ever run enough wire thru a tip to wear one out. However I frequently see students who monkey with the settings get the wire speed so low for the voltage chosen that the wire burns back and fuses to the tip..No government ever voluntarily reduces itself in size.

Reply:Based the feedback I've read on the MM 211, the unit sounds like it produces a crisp arc. This style of arc tends to be more challenging to dial in a light spatter level with then a unit that has a softer style arc.  As you increase the voltage a crisp arc becomes harsher, and spatter increases. Your best option to help reduce the spatter level on 1/4', may be to switch to an .035 wire. A light coat of anti-spatter on the base metal will keep a high percentage of the spatter from sticking to the base metal.ESAB Migmaster 250 Hobart Ironman 230Multimatic 215TWECO Fabricator 181i & 211iHH125EZ - nice little fluxcore only unitMaxstar 150 STH - very nice
