i recently purchased some Industrial and Scientific consumables and was extremely disappointed by the poor quality. Thanks to my knowledge gained in practice I can confidently say that these are not up to standard and will not last as long as other options .The only pro is that they are affordable, but even that pales in comparison to their lackluster durability. Overall, I would not recommend these products..
Pros
Durable and long-lasting for heavy-duty applications.
Cons
Prone to wear and tear over time with frequent use.
tips were at a good price. But they don't last very long. The factory spikes lasted two weeks but burned out four new ones on a cut of 16-gauge sheet metal
Pros
Package included: 10pcs cup 15pcs electrodes 20pcs ring 25pcs tip (general)
