1. Technical Performance & Maintenance

Q: How often do the filter cartridges in LW1201 normally need to be replaced during MAG/TIG welding?

A: The theoretical service life of the LW1201 filter cartridge is about 6,000–8,000 hours (approx. 1 to 1.5 years). However, under heavy MAG/TIG fume volume, high oil content, or continuous operation, replacement may be required after about 6 months.

Q: What are the filtration accuracy and purification efficiency of the Ahlstrom nano flame-retardant filter cartridges used in LW1201?

A: The cartridges feature a filtration accuracy of 0.5 microns and a purification efficiency of over 99%.

2. Safety, Quality & Construction

Q: How good is the fire safety performance of LW1201 during high-temp welding, and what fire protection measures are adopted?

A: LW1201 features a 3-stage built-in fire protection design:

1. A built-in fire protection mesh in the suction arm hood blocks large welding slag and sparks.

2. A flow-diversion baffle inside the unit slows down airflow and extinguishes stray sparks by impact.

3. Flame-retardant filter cartridges with an F1 material rating are used.

Q: What material and process are used for the housing of LW1201, and is it rust/corrosion-proof?

A: Sheets are laser-cut and CNC cold-formed/pressed, then joined via automatic welding. The housing receives an industrial-grade electrostatic powder coating (≥100μm thickness), fully meeting rust-proof and anti-corrosion standards.

Q: What tests are carried out on LW1201 before leaving the factory?

A: Each LW1201 unit undergoes strict current, air velocity, air pressure, noise, appearance, electrical performance, airtightness, and mobility testing to ensure premium product quality.

3. Customization, Voltage & Warranty

Q: Can LW1201 be customized for different countries' voltages and frequencies?

A: Yes. Custom motors, transformers, and components are configured based on target country standards. Lead time for custom LW1201 units is typically 15–25 working days.

Q: Can the surface color of LW1201 be customized?

A: Yes, color customization is available. It is free of charge for orders of 10 units and above, while a partial fee applies for orders under 10 units.

Q: Can the start/stop switch be located at the workstation if LW1201 is placed outdoors?

A: Yes. We can add a wired remote control switch based on your required distance, functioning identically to the main switch on the LW1201 housing.

Q: How long is the warranty period for LW1201?

A: The main sheet-metal structure is warranted for 3 years, and the fan and main electrical components for 1 year. (Filter cartridges are consumables and not covered by warranty).
