Complaint
| 1). Anti-stick--allows you to easilly withdraw you electrode without damaging it in case of sticking | ||||
| 2). ARC force--increases the current in order to avoid the sticking when electrode enters in melted metal | ||||
| 3). Hot Start--increases the current at the beginning of the welding | ||||
| 4). Famous brand IGBT chips(FAIRCHILD from USA) | ||||
| 5). SMT technology which highly reduced the PCB board broken rate | ||||
| 6). Thermostatic, overvoltage, undervoltage, overcurrent protections | ||||
| 7). Usable electrodes: Rutile, basic, stainless steel, cast iron, etc. | ||||
| 8). Complete accessories--electrode holder, earth clamp with cable; Mask and brush. |
