Welding Capacity | Heavy industrial fabrication | Industry Standard: 250A max current (AC) Our Base: 315A DC TIG▲ Our Advanced: 400A DC TIG▲▲ (TIG400 model) | ▲34% higher output than AC standards for thick metals ▲▲16% boost in Base→Advanced tiers | Higher amperage requires specialized safety training (e.g., for 400A models) |
Power Efficiency | Mobile welding operations | Industry Standard: 75% efficiency (traditional transformers) Our Base/Advanced: 90% DC inverter efficiency▲▲ | ▲▲15% energy savings vs. industry norms Lightweight design (18kg Base vs. 22kg Advanced) | Advanced models may have shorter battery life in portable setups (-10% runtime) |
Material Compatibility | Stainless steel/carbon steel welding | Industry Standard: Limited to AC polarity (e.g., aluminum) Our Base/Advanced: DC TIG polarity▲ (ASTM A370 certified) | ▲Double-sided corrosion resistance for stainless steel▲ No post-weld cleanup needed | Incompatible with aluminum (requires AC TIG for non-ferrous metals) |
Portability | On-site construction projects | Industry Standard: 25+kg (non-inverter) Our Base: 18kg▲ Our Advanced: 22kg (adds auto-current feature) | ▲30% lighter than competitors Integrated carry handle for mobility | Advanced model’s weight gain reduces stair-climbing convenience by ~20% |
Control Precision | Precision engineering (e.g., aerospace) | Industry Standard: Analog dials (±10% error) Our Base: Digital display (±2% error)▲ Our Advanced: Auto-current▲▲ | ▲▲8x more accurate than analog systems Real-time parameter monitoring | Advanced model requires 2-hour training to master auto-current settings |
Safety Features | High-risk environments (e.g., offshore) | Industry Standard: Basic thermal guards Our Base: Heat-resistant cover▲ Our Advanced: Arc-eye protection▲▲ | ▲50% lower spark exposure risk▲ ▲▲UV radiation shielding for operators | Advanced safety adds $150 to cost vs. Base tier |
