Pneumatic AC or variable frequency seam welding machine / longitudinal seam welding machine

Classification

As per power source: AC and inverter DC
As per welding wheel direction: Horizontal and longitudinal
As per qualiy grade: Top quality and simple type

Features

1. Adopt 3-phase motor which is variable frequency, average welding speed, easy to adjust, and stability.
2. Welding circuit loop is by means of internal water cooling, welding wheel (electrode) are by means of external water cooling.
3. The parts of electric conduction turning on welding machine are designed to be embedded silver bushings structure, the base of electric conduction is lubricated by hermetic oil and be cooled down by water so as to silver bushings turn flexibly not to lock.
4. Both horizontal and longitudinal two type seam welders. H: Horizontal, L: Longitudinal.
