I have just recently taken up welding and purchased an ESAB MultiMaster 260. It has an option for Pulse Mig capability (that I did not purchase) and I was wondering what is the bennifit of Pulse Mig.
Pulsed mig, depending on material thickness to be welded has many advantages over conventional mig.
1) Amp for Amp, more/better penetration values compared to Standard mig
2) Eliminates the need to use a thin wire eg 0.8mm for welding thinner sheets and a 1.2mm for welding thicker sheets. With Pulse, even very thin material can be welded with a larger diameter wire. 1.2 wire could weld 0.9mm plate for example.
3) No mixed arc phase with pulse welding, its a kind of Spray arc for all thickness's.
4) Hardly any spatter in some cases non at all.
5) No need to worry about selecting correct Inductance, this would be done electronically/automatically.
6) Superb on Aluminium and CrNi where Standard mig tends to be troublesome.
Thank you for this information, it was exactly what I needed to know. You should write the product info sheet for ESAB because what seems to me as important product information is completely lacking from their description.
Pulse Migs are relatively new (well sort of) and as yet are expensive, no doubt in time the price will drop. Pulse on pulse or double pulse or what ever the manufactures want to call it produce near tig quality welds on ally
