Prevents tungsten electrode erosion and work-piece tungsten contamination by initiating the electric arc across an ionized gas gap without physical electrode contact. Essential for high-purity pharmaceutical piping, food processing equipment, and nuclear grade welds.
Allows fine-tuning of peak current, base current, pulse frequency, and pulse width. Minimizes overall heat input into heat-sensitive alloys (such as thin stainless steel sheet or titanium), preventing metal distortion, burning through, and heat-affected zone (HAZ) degradation.
Adjustable pre-flow purges atmospheric air from the torch region prior to arc strike, while post-flow protects both the cooling weld pool and the hot tungsten tip from oxidation immediately after arc termination, ensuring bright, defect-free weld beads.
On AC-capable models, operators can precisely balance oxide-cleaning action against penetration depth when welding aluminium and magnesium alloys. This breaks down stubborn oxide films while concentrating thermal energy into deep metal penetration.
Paragweld operates a rigorous Quality Assurance protocol adhering to international manufacturing directives. Every TIG welder machine undergoes stringent dielectric insulation testing, full-load temperature rise testing, and continuous burn-in trials prior to export dispatch.
Essential details for B2B importers, distributors, and EPC contractors.
We accept sample orders starting at 1 unit for evaluation. For commercial wholesale distributor orders, volume discount pricing applies to FCL and LCL shipments.
Yes, our electrical engineering team configures TIG welding machines to match specific national electricity standards, including 220V 1-phase, 380V 3-phase, 415V 3-phase, and 440V 3-phase at 50Hz or 60Hz.
For continuous TIG welding above 250 Amperes or during heavy multi-shift production, we strongly recommend integrating a Paragweld recirculating water-cooling unit to protect the TIG torch neck, cable assemblies, and internal power components from thermal fatigue.
