General Questions
We serve a wide range of industries including oil and gas, petrochemical, construction, manufacturing, automotive, shipbuilding, aerospace, power generation, and general fabrication. Our solutions are suitable for both heavy industrial applications and light fabrication work.
Yes, we provide international shipping services to multiple countries. Delivery times and costs vary based on destination and order size. Contact our sales team for specific shipping information.
All welding equipment sold by TIG TRADING LTD comes with manufacturer's warranty. Warranty periods vary by product and manufacturer, typically ranging from 1 to 3 years. Extended warranty options are available for select equipment.
Absolutely. We provide comprehensive after-sales technical support including installation guidance, operation training, troubleshooting assistance, and maintenance services throughout the equipment lifecycle.
Product Selection
The ideal welding machine depends on several factors including the type of metal you'll be welding, material thickness, duty cycle requirements, portability needs, and available power supply. Our technical team can assess your specific requirements and recommend the most suitable equipment.
- TIG (Gas Tungsten Arc Welding): Offers the highest precision and cleanest welds, ideal for thin materials and critical applications. Slower but produces superior quality.
- MIG (Gas Metal Arc Welding): Fast and versatile, excellent for production welding and thicker materials. Easier to learn and more productive.
- Stick (Shielded Metal Arc Welding): Most portable and versatile for outdoor/field work, works well on rusty or dirty materials, commonly used in construction and maintenance.
Yes, we maintain extensive inventory of consumables compatible with major welding equipment manufacturers including Lincoln, Miller, ESAB, Fronius, Kemppi, and many others.
Consumables & Materials
Selection depends on the base metal composition, joint configuration, welding position, and required mechanical properties. Refer to welding procedure specifications (WPS) or consult our technical team for recommendations based on AWS/ISO standards.
Properly stored low-hydrogen electrodes typically have a shelf life of 6-12 months in original sealed packaging. After opening, they should be stored in a heated rod oven at 100-150°C to prevent moisture absorption. Rutile electrodes are less sensitive but should still be stored in dry conditions.
While technically possible, we recommend using consistent brands and types to ensure predictable weld quality. Always verify that consumables meet the required specifications for your application regardless of brand.
Safety & Compliance
Welding helmets should meet ANSI Z87.1 standards for eye protection in the United States, or EN 379 in Europe. Auto-darkening filters should have appropriate shade ranges (typically 9-13) and fast switching speeds (1/10,000 second or faster).
Yes, we provide Safety Data Sheets (SDS, formerly MSDS) for all chemical products and welding consumables. These documents contain important safety, handling, and emergency information.
Adequate ventilation is critical for welding fume extraction. Requirements vary based on materials being welded, process type, and workspace volume. Local exhaust ventilation, general dilution ventilation, or respiratory protection may be necessary depending on exposure levels.
Equipment Maintenance
We recommend annual preventive maintenance for most welding equipment under normal use. High-duty cycle or critical applications may require more frequent service. Regular cleaning, inspection, and consumable replacement should be performed monthly or per manufacturer guidelines.
Yes, our service department can repair and maintain welding equipment regardless of where it was purchased, subject to parts availability and technical feasibility.
We maintain inventory of common spare parts for current equipment models and can source parts for older equipment through our manufacturer networks. Lead times vary depending on part availability.
Ordering & Delivery
Minimum order quantities vary by product type. Welding consumables like electrodes and filler rods may have minimum quantities per size/specification, while equipment typically has no minimum. Contact us for specific MOQ information.
Yes, we provide competitive volume discounts for bulk orders and long-term supply agreements. Our sales team can prepare custom quotations based on your specific requirements.
In-stock items typically ship within 24-48 hours. Custom orders or special items may require 2-4 weeks depending on manufacturer lead times. We can arrange express shipping for urgent requirements.
CReturns are accepted within 30 days of delivery for unused, unopened products in original packaging, subject to a restocking fee. Welding consumables, cut-to-length materials, and custom items are generally non-returnable. Please review our complete return policy or contact customer service.
Technical Support
While we don't provide certified WPS documents (which require proper qualification testing), our technical team can offer guidance on developing procedures and recommend appropriate filler metals and parameters based on industry standards.
Yes, our experienced technical team can assist with troubleshooting common welding problems including porosity, cracking, poor penetration, distortion, and other weld defects. Contact us with details about your application and the issues you're experiencing.
On-site technical support is available for equipment commissioning, operator training, and complex troubleshooting. Service charges and travel expenses apply. Contact our service department to arrange on-site support.
