China Suppliers Factory 250A Household HF Pulse AC DC Inverter TIG MMA Welder with IGBT Technology
Detailed Information
- Small Heat Affected Area: There is no heat input during the instant process of stacking, avoiding deformation, undercut, and residual stress. No partial annealing occurs, and reheat treatment is not required after repair.
- Minimal Welding Impact: This machine overcomes the impact phenomenon of ordinary argon arc welding on the workpiece periphery. Repairs can be performed confidently even on machined surfaces without allowance.
- High Repair Accuracy: Surfacing welding thickness ranges from a few microns to a few millimeters, requiring only grinding and polishing.
- High Welding Strength: Full penetration into the surface material of the workpiece produces a strong bonding force.
- Easy to Carry: Weighs only 8.5 kg, runs on a 220V power supply, and has no specific working environment requirements.
- Economical: Offers immediate on-site repair, improving production efficiency and reducing costs.
- Multi-Functional: Performs surfacing welding, surface strengthening, and more. Thickness and smoothness can be controlled by adjusting discharge power and frequency.
- Hardness Versatility: Different hardness requirements (HRC 25 to HRC 62) can be achieved by using different electrode rod materials.
- Gas Protection System: Features a microcomputer-controlled synchronous argon protection system, ensuring solid and beautiful welds while maximizing argon savings.

Frequently Asked Questions (FAQ)
1. What are the key advantages of the microcomputer-controlled gas protection system?
The welder utilizes a synchronous argon protection system controlled by a microcomputer. This improves argon protection, resulting in a more solid and beautiful weld, while significantly saving argon gas during operation.
2. Does this welding machine cause workpiece deformation or undercut?
No. Because the heat-affected area is extremely small and there is no heat input during the instant process of stacking, it prevents deformation, undercut, and residual stress. Reheat treatment is not required after repair.
3. What is the hardness range of the surfacing repair layer?
Depending on the electrode rod material (supplementary materials) used, the hardness of the surfacing repair layer can range from HRC 25 to HRC 62.
4. What types of welding rods can be used with this machine?
The machine is highly versatile and supports acidic, alkaline, and stainless steel welding rods for stable and reliable welding.
5. What are the installation and ambient requirements for the machine?
It requires an input voltage of 380V AC±10%, a power switch of 63A, and operates in ambient temperatures between -10℃ to +40℃. The usage environment should be well-ventilated, dry, and protected against dust, moisture, and water.
6. Is this welder easy to transport for on-site repairs?
Yes, the machine is highly portable with a weight of only 8.5 kg and operates on a 220V power supply, requiring no specialized working environment.
