Main characteristics:

The TDW 2500MB welding machine has all the functions of the TDW 3000MB pul<'sed TIG welding machine: in the argon arc welding stat‍±♦¥e, it can perform stable welding op§<eration with a welding cur←δ‍rent of 5A and have the simple TIG welding function in the state of MMA welding mode. The low-load voltage output, line e↓β£≠nergy monitoring related func↓δ±tions etc can be set i₹αγ∏n the state of MMA welding.
