250A Household HF Pulse AC DC Inverter TIG MMA Welder - China Suppliers & Factory Quality Welding Equipment
Detailed Information
- 1. 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.
- 2. Minimal Welding Repair Impact: Overcomes the impact phenomenon of ordinary argon arc welding on the workpiece periphery. Repairs can be performed confidently even on machined surfaces without allowance.
- 3. High Repair Accuracy: Surfacing thickness ranges from a few microns to a few millimeters, requiring only grinding and polishing.
- 4. High Welding Strength: Full penetration into the surface material produces a strong bonding force.
- 5. Easy to Carry: Lightweight design (8.5 kg), 220V power supply, with no working environment restrictions.
- 6. Economy: Immediate on-site repair improves production efficiency and saves costs.
- 7. Multi-Functional: Performs surfacing welding, surface strengthening, and other functions. Thickness and smoothness are adjustable via discharge power and frequency.
- 8. Hardness and Material Diversity: Different hardness requirements (ranging from HRC 25 to HRC 62) are achievable using different electrode rod materials.
- 9. Gas Protection System: Upgraded to a microcomputer-controlled synchronous argon protection system, ensuring solid and beautiful welds while maximizing argon savings.

Frequently Asked Questions
Does the welding process deform the workpiece?
No. The heat-affected area is extremely small because there is no heat input during the instant process of stacking, resulting in zero deformation, undercut, or residual stress.
What hardness can be achieved on the surfacing repair layer?
The hardness of the surfacing repair layer can range from HRC 25 to HRC 62, depending on the electrode rod materials utilized.
What are the required installation specifications for power and cabling?
The system requires an input voltage of 380V AC±10% (50/60Hz), an input cable of ≥6 mm², an output cable of 50mm² (with a welding gun ≦15m), and a 63A power switch.
What standard accessories come with the machine?
Standard accessories include 1x Electrode Holder, 1x Ground Clamp, 1x Welding Mask, and 1x Brush/Hammer.
What are the environmental usage requirements?
The machine should be operated in temperatures between -10℃ and +40℃ under good ventilation conditions. Care should be taken to protect the device from dust, moisture, and water.
