Only using an oscillograph you can ind out if you are in the short-circuit transfer mode. Check those links:
As a "general rule"
Typical A range: 30-200 A
Typical V range: 16-22V
wire diameter: below 1,2 mm
Heat input low, risk of lack of fusion
Ho The above is only indicative. Only the oscillograph can tell you the trough

Arc Voltage less than 21v is a short circuit/Dip transfer mode--THANKS & BEST REGARDS,KG.PANDITHAN, IWE, AWS-CWI, CSWIP 3.1,CONSULTANT-WELDING & QUALITYMobile no: +919940739349On Sun, Feb 19, 2017 at 10:16 PM, Prasad Rode <purode333@gmail.com> wrote:
Dear sir,
All of we know that in GMAW process, there are three metal transfer techniques.
1) spray transfer.
2) globular transfer
3) short circuiting.
We know that, as per different temperature, voltage and with different shielding gases also, different technique generated.
But, on site and in practicality, how we come to know that welder is using which type of technique.
Regards
Prasad
