Astro Arc Polysoude Inc  

The UHP 625 completes and enlarges today’s UHP (Ultra-High Purity) welding head range. With the UHP & MW series and the P4-3 power source, Polysoude now offers a complete solution to tackle the high purity market (semiconductors, bio-chemistry, pharmaceutical industries, food & beverage, …).

Key Features:

• Guaranteed constant quality by the closed loop regulation to ensure precise welding speed
• Removable fixture-block which facilitates the positioning of the precision tubing, fittings or micro-fittings to be welded providing perfect tube end centering and alignment.
• The integrated remote control allows the start of a welding cycle without any action on the power source (no need to use the touchscreen or the remote-control pendant). Polysoude is the only orbital welding equipment manufacturer who provides this advantage.

Open welding head designed for all weld joint configurations (protruding, flush, recessed, backplate).

Pneumatic clamping/centering system, motorized Arc Voltage Control (AVC) or programmable electrode height, tilted AVC for low protruding applications & fixed or rotating wire feeder

Key Features:

• Compact: reduced size & weight
• Ergonomic: double handle with integrated remote control for clamping & welding
• Productive: simultaneous use of multiple welding heads with pneumatic clamping & centering system by one operator
• Simple: simplified mechanical adjustments (ie wire positioning)
• Automatic: standard version with AVC (Arc Voltage Control) & tilted AVC for low protruding applications, return-to-home feature (electrode automatically returns to its starting position)
• Precise: on board wire feeder (fixed or rotating) for constant wire feeding & accurate wire impact position
• Accurate: encoder based position control
• Quality: endless rotating torch with no cable winding using a unique collector to supply the torch with welding current, shielding gas and cooling liquid
• Versatility: pneumatic self-supporting, dual-turret clamping, reinforced pneumatic clamping for large diameters, back plate & double plate header-box welding lances, gaseous environment shroud, …
• Compatibility: all suitable Polysoude power sources
• Designed for high duty cycle applications with high temperature resistant materials and closed loop water cooling

Key Features:

Closed chamber welding heads are specially designed for autogenous welding of tubes without filler wire. Excellent results can be achieved when welding austenitic stainless steel, metals susceptible to oxidation, such as titanium, or alloys such as Inconel.

The MW 34 has the dimensional advantage of a UHP 1500 and the duty cycle of an MW welding head. The MW 34 closed chamber welding head bridges the gap between the UHP 250/500 (micro-fittings) and the MW series (Food & beverage, pharmaceutical industries).
