Custom Designs VHI-I The configuration of this machine can present certain types of weld joints for flat position welding. This incline configuration optimizes cosmetic appearance and speed. A synchronized rotary drive rotates the opposing "inclined" spindles at the same speed. This maintains the radial alignment between two parts with no chance of slippage. Rotary air unions for air clamps are available. This machine is available in 1 or 2 weld head configurations for MIG, TIG or plasma welding.
