ARO's Stationary Spot Welding Machines
Being a relative simplicity spot welding can soon become complex due several factors, starting by the specificity of the part itself, its design, the welding strength and aspect required, and the production cycle time expected. the machines can be:
- AC or MFDC for the welding current.
- Servo (equipped with force sensor for force control and monitoring) or Pneumatic for the welding force for the Omega, P, and MOS series.
- Several options are available
