I would thus like to welcome you to join us for a practical demonstration, so you can see and test our wires in reality yourself. So if you are interested please contact me. Meanwhile, my best regards and please stop by my channel from time to time, as I will be adding more movies with hands-on advice.

Highly positive feedback from satisfied customers and partners in various industries worldwide, as well as constant face-to-face interaction with welders and welding engineers during practical demonstrations, tell a different story.

Dear Sir/Madame, I thank you for your interest in the movie and especially your passion for welding. As for your comments I would like to point out that a camera perspective in close-up is by no means able to reproduce or fully portray the performance of the wire nor the actual welding characteristics.

The amount of spatter produced by the flux core wire in this video should give the viewer cause for concern.

I believe the welder has selected WFS and Voltage parameters that result in a globular-type transfer mode, rather than the more desirable spray-like transfer mode that produces very little spatter. The welder may be using a wire size too large than would be ideal for all-position welds, forcing him to use parameters that are too cold in order to produce a controllable puddle size.

This is a common mistake when welding with flux-core wires in non-flat positions, using wire sizes that are too large. with wire sizes greater than 1.2mm in order to produce smooth spray-type transfer, it would require voltage and current levels such that the weld puddle becomes too large and very difficult to control in other than the flat position. Also the weld deposition rate benefits of using >1.2mm wires become minimal for the same reasons, welders are forced to reduce the WFS and volts
