Do you have these troubles?

Galvanized steel sheets
Electrode grinding
Restraint the splash
Burn and strain
Welding quality.
Effecting reducing the voltage fluctuation.

Solve the problems

Secondary constant current control
The single phase A.C. Welder machine is transformed
The Welding condition can be transmitted to the program box with the memory
The seam weld can be speed up.

Current not consistency
Part rejection very high
Worry of welding quality
High power input consumption
Long weld time

Change new super inverter mesa AIT series
No need controller
No need thyristor
Old machine parts service

Working Smooth
Good output quality
Constant current output
Low power input (40% lower compare AC machine)
Shorter weld time
