Q&A:
Q:What's MIA power source.
A: MIA is short of Made in Auto, it can also get very good and steady welding performance. And such series of tank welding machines have been used in many project site.
 
Q: Is there any tank diameter limit when using hydraulic jacking system? Can it be used in big tank?
A: Hydraulic jacking system is not limited by tank diameter, but it depends on tank weight. It can be used in big diameter tank.
