These welding machines are a power source for arc welding operations, custom-built for TIG (DC) LIFT and MMA welding of coated electrodes (rutile, acid, basic). The high level of speed and calibration accuracy are particular aspects of this welding machine (INVERTER) and guarantee top quality welding. The inverter regulating system at the feeder line input zone (primary) also determines a marked drop in volumes related to the transformer and levelling reactance which makes it possible to build an extremely low volume, lightweight welding machine, making handling and transportation much easier.
Main features
- Direct current (DC) TIG (LIFT strike) and MMA electrode inverter welding machine, 170A, with LCD display.
- MMA welding with arc-force adjustment and presence of hot-start devices; welds rutile, basic, stainless steel and cast iron electrodes up to Ø 4mm.
- With set welding current display.
- Thermostatic, overvoltage, undervoltage, overcurrent protection. Compatible for use with the motor generator (230V, +/-15%).
- VRD device for greater safety in welding operations in damp environments.
- Light and compact. Easy to transport. Contained consumption thanks to inverter technology.
- Arc Force and Hot start functions
- Complete with TIG/MMA welding accessories and plastic carry case.
The Voltage Reduction Device (VRD) is used to decrease the output voltage to a safe level when the welding machine is on but not in welding conditions. This grants the operator's safety: he can come into contact with the electrode without risks, until welding operations are resumed. (for use in damp environment such as mines or shipyards, etc.).
