Frequently Asked Questions

What is the difference between MOSFET and IGBT HF welders?

MOSFET systems operate at higher frequencies (100–500 kHz) and are ideal for thin-walled tubes. IGBT systems offer higher power (up to 800 kW) and are better suited for thick materials and lower frequencies (10–100 kHz).

How long does installation and commissioning take?

Standard systems can be commissioned in 5–7 days. Custom lines may require 2–3 weeks depending on complexity and site conditions.

Do you offer technical support and training?

Yes. We provide on-site or remote commissioning, operator training, and 24/7 technical support via email, WhatsApp, and phone.

What certifications do your machines have?

Our equipment complies with CE standards and undergoes rigorous internal quality testing. Factory acceptance tests (FAT) are conducted before shipment.
