China Suppliers Factory 250A Household HF Pulse AC DC Inverter TIG MMA Welder for Efficient Welding Solutions
Detailed Information
- The heat affected area is small. There is no heat input during the instant process of stacking, so there is no deformation, undercut and residual stress. No partial annealing occurs, and reheat treatment is not required after repair.
- Extremely small welding repair impact, this welding machine overcomes the impact phenomenon of ordinary argon arc welding on the periphery of the workpiece during the welding repair process. Repairs can be performed with confidence even on the machined surface of the workpiece without allowance.
- High repair accuracy: the thickness of surfacing welding is from a few microns to a few millimeters, only need to be ground and polished.
- High welding strength: due to the full penetration into the surface material of the workpiece, a strong bonding force is produced.
- Easy to carry: weight (8.5 kg), 220V power supply, no working environment requirements.
- Economy: Immediate repair on site, improving production efficiency and saving costs.
- One machine with multiple functions: it can perform surfacing welding, surface strengthening and other functions. The thickness and smoothness of surfacing and strengthening can be obtained by adjusting the discharge power and discharge frequency.
- The hardness of the surfacing layer and the diversity of supplementary materials: different hardness requirements can be obtained by using different electrode rod materials (supplementary materials). The hardness of the surfacing repair layer can range from HRC 25 to HRC 62.
- Gas protection system: It is changed to a synchronous argon protection system controlled by a microcomputer, which makes the argon protection better, and the welding effect is more solid and beautiful. At the same time, it maintains the original advantages, comparable to expensive laser welding machines, and can save argon to the greatest extent.

Frequently Asked Questions
What are the primary benefits of the low heat input feature?
Because there is no significant heat input during the instant stacking process, the heat affected area remains extremely small. This eliminates common welding issues such as deformation, undercut, and residual stress. Additionally, no partial annealing occurs, which means reheat treatment is not required after repairs.
Can this machine be used to repair precision-machined surfaces?
Yes. The machine features an extremely small welding repair impact, overcoming the peripheral impact issues associated with standard argon arc welding. This allows you to perform repairs reliably even on precision-machined surfaces with zero allowance.
What is the hardness range of the surfacing repair layer?
Depending on the electrode rod materials (supplementary materials) selected, the hardness of the surfacing layer can range from HRC 25 to HRC 62, offering great versatility for different hardness requirements.
How does the gas protection system optimize argon use?
The welder features a synchronous argon protection system controlled by a microcomputer. This system optimizes gas flow, providing stronger and more aesthetically pleasing welds while saving argon to the greatest extent possible.
What environmental and power conditions are required for installation?
The unit requires either a 220V or 380V AC±10% input voltage (depending on the model) and a 63A power switch. It should be used in well-ventilated environments within a temperature range of -10℃ to +40℃, with adequate protection against dust, moisture, and water.
