Re: [MW:12625] Mode of transfer

The mode of transfer must be spray transfer if the Current and voltage above / around 250 Amp and 30V.   Wave form  and mode of tranfer both are different.  Wave form given the type iof current, AC or DC , up slope, down slope etc which controls the arc, where the mode of transfer dependent on current, voltage and type of shielding.  CO2 gas heavier than arogo shield gas.

Dear Experts
We are interested to find out the mode of transfer during welding ( GMAW with 80% Argon and 20 % CO2 mix gas.) An oscilloscope was conneted in series to the invertor based welding machine and the waveform obtained is depicted in the photo. Please let me know from the wave form can we comment on the mode of transfer
With regards
