Fronius 2700 Pulse Mig

admin

Just got a Fronius 2700 TPS welder, double pulse etcCan anybody help me with the machine setting for welding aluminumWhen I enter the plate thickness the weld does not have enough heat for the weldWent back to the old theory of 1 amp per 1 thou of material and it works findLocal Fronius rep not very helpfulWould like any info on setting to get this machine singing
Reply:Not familiar with that particular machine but: If you are in a mode where you set plate thickness and it determines the WFS, make sure it is set for aluminum and not steel. Aluminum needs much higher WFS than steel for the same diameter of wire.I'm surprised that your rep wasn't able to help you, Fronius has a very good reputation for service. Maybe try to talk to another person there.JohnA few weldersA lot of hammersA whole lot of C-clamps

Reply:Not that the Miller and Fronius work the same way, but even with Miller's hot start the start of aluminum welds looks a bit on the cold side.  The major adjustment for heat on the Miller is wire speed.  More wire and you get significantly more heat to the point were you melt through the material.On all these semi-automatic machines it is extremely important the wire feed is working perfectly.  The machine assumes if your are commanding 350 ipm, that you are getting 350ipm and it adjust voltages accordingly.On the Miller, if you see the arc length changing, you have wire feed issues (assuming you are still in hot start or entering crater fill part of the program).Con Fuse!Miller Dynasty 350Millermatic 350P-Spoolmatic 30AMiller Multimatic 200Hypertherm PowerMax 1000G3Miller Maxstar 200DX

Reply:Set your machine for 240-265 ipm with .035 wire and adjust arc length till you get a desired heat setting for the size of weld you are doing.  The pulse requires a little different technique then standard aluminum welding, a slight back step weave usually does the trick for me.  Make sure you are using a heavy argon mix, if you have access to an alumix from airgas, that is preferable.  IF you have any further questions, email me at [email protected]   I am highly experienced with the fronius machine, there are allot of settings to use at your benefit, to better understand them go to Ed's website at weldreality.com
