Household HF Pulse AC DC Inverter 250A TIG MMA Welder

1. 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.

 

2. 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.

 

3. High repair accuracy: the thickness of surfacing welding is from a few microns to a few millimeters, only need to be ground and polished.

 

4. High welding strength: due to the full penetration into the surface material of the workpiece, a strong bonding force is produced.

 

5. Easy to carry: weight (8.5 kg), 220V power supply, no working environment requirements.

 

6. Economy: Immediate repair on site, improving production efficiency and saving costs.

 

7. 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.

 

8. 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.

 

9. 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.
