How to Select Plasma Welding Machines   Image Credit: Bug-O Systems | Wilead   Plasma welding machines melt areas with an arc and then use a high-velocity, high-temperature ionized gas to make welds. The process of plasma welding is used to bring better control to the arc welding process in lower current ranges. It provides an advanced level of control and accuracy in order to produce high quality welds in miniature or precision applications and to provide long...

Q:
Do you know of any disastrous mistakes that occurred due to the incorrect usage of plasma cutting and welding machines?

Q:
Is there any advice you want to share with users to help them avoid common errors in selection or usage of plasma cutting and welding machines?
8 answers
Answers:
Trying to cut with the "rated" thickness is never a good idea! [see above] also, sometimes the old oxy/acet torch is still the way to go! If you're disassembling there usually isn't a need for a "pretty" cut.
~Marketing/Sales, BANGOR, ME
Check first how many pieces used for work.- consumables! some are very expensive
~Arturo Sierra Saw, Technical salesman, Puebla, Mexico
Backup on spare / wear part and application optimisation on usage.
