We just got a new (G6 I think) Panasonic welding robot (it does both TIG and MIG welding, we r currently only programming MIG) at work. I have done plenty of programming on our older panasonic welding robots, but this new one uses a different gas mix and so I have been experiencing serious frustration in trying to write working programs with clean (no porosity or weld bubbles) strong welds. We r welding mostly thinner material right now (aluminized steel). I can get the robot to weld with out burning through, but the welds are still either skimpy or porous (bubbles) or both. I am guessing I need to adjust the amps, volts, traveling speed, or wire feed speed. just not sure what to adjust or how much. I currently have it about amps=110, volts=17.5, traveling speed (varied) anywhere from 22-40 depending of location of the weld. Have had some success with adjusting the wire feed speed to around 60-70, but was told by another programmer this should not be modified (she say it musts be it at 10 always, but she isn't sure why?) Also we are using a 75/25 gas mix, our older robots are set up to use a 80/20 gas mix which they want to change to 75/25 on those also after we figure out how to adjust our accordingly programs. Please if anyone has any ideas that could help I would be very greatful!
how do I adjust settings (amps, volts, traveling speed, also wire feed speed)for

What brand, type and size wire are you using? You can look up data sheets on manufacturers websites for typical settings used. It may give you a baseline. What is the AL/steel material thickness in mm? Are you in CV mode or are you trying to pulse? I wouldn't want to hazard a guess at settings until I knew those details. If you have porosity in your welds you may be getting aluminum inclusion in your welds which indicates you may not be hot enough to flash off that layer. Is your gas mix and flow rate stable? Generally, the higher the co2 content the higher the voltage. You mention setting wire feed speed at 60-70 which is very low. Prior to that you talked about amps. Are you setting amps or wfs in your program?
