 | ◉ TIG and MMA welding Use TIG for controlled welds and MMA for general repair work. ◉ Up to 200 A TIG and 160 A MMA output at 220V Provides a choice of welding currents for different jobs. ◉ 110/220 V input options Works with either supported voltage for use at different job sites. |
◉ Single-pulse TIG Provides more control over heat input during welding. ◉ Current upslope and downslope Raises and lowers the current gradually for smoother weld starts and finishes. ◉ Adjustable gas post-flow Keeps shielding gas flowing after welding to protect the tungsten and cooling weld. |  |
 | ◉ 4.8 kg machine weight Easy to carry between work areas and take to on-site jobs. ◉ Overheat and over current protection Helps protect internal components from overheating and excessive current. ◉ Digital control Welding parameters can be configured at the factory to suit your requirements. |
Q1. What welding processes does the WSM-250 support? A1. The WSM-250 supports both TIG welding and MMA (Stick) welding in one inverter power source, making it suitable for fabrication, maintenance, installation and general repair applications. Q2. Does the WSM-250 support both 110V and 220V power? A2. Yes. The WSM-250 operates on both 110V and 220V single-phase power (50/60Hz), allowing users to work in different power environments without changing machines. Q3. What is the maximum welding output? A3. On 220V input, the machine provides up to 200A TIG output and 160A MMA output. On 110V input, the maximum output is 120A for both TIG and MMA welding. Q4. What materials can the WSM-250 weld? A4. The WSM-250 is suitable for TIG and MMA welding on carbon steel, stainless steel and other compatible metals. Material suitability depends on the selected welding process and consumables. Q5. What welding thickness can the WSM-250 handle? A5. The rated TIG welding thickness is 0.3–10 mm on 220V and 0.3–5 mm on 110V. Actual welding capacity may vary depending on the material, joint design and welding technique. Q6. Which electrode sizes are recommended for MMA welding? A6. The recommended MMA electrode diameter is 2.5–4.0 mm on 220V and 2.5–3.2 mm on 110V for stable welding performance. Q7. What accessories are included with the WSM-250? A7. The standard package includes a WP-17 TIG torch and a ground cable. Additional accessories and customized package configurations are available upon request. Q8. Can the WSM-250 be customized for OEM or private-label orders? A8. Yes. We provide OEM and private-label services, including custom logos, housing colors, packaging, user manuals and branding solutions based on customer requirements. Q9. Which certifications are available for export? A9. Certification availability depends on the destination market and product configuration. Please let us know your market requirements so we can confirm the applicable certifications before production. Q10. What shipping options are available for international orders? A10. We support shipment by express, air, sea and railway freight. Commercial invoices, packing lists and standard export documents can be provided to assist with customs clearance. |
