2 . GENERAL INFORMATION
2.1 INTRODUCTION
- This welding machine is a power source for MMA welding and scratch strike TIG welding, made specifically for direct
current (DC).
The specific characteristics of this regulation system (INVERTER), i.e. high speed and precise regulation, mean the
welding machine gives excellent results when welding with coated electrodes (rutile, acid, basic).
Regulation with the “inverter” system at the input of the power supply line (primary) means there is a drastic reduction
in the volume of both the transformer and the levelling reactance. This allows the construction of a welding machine
with extremely reduced weight and volume, enhancing its advantages of easy handling and transportation.
2.2 OPTIONAL ACCESSORIES:
- MMA welding Kit.
3. TECHNICAL DATA
DATA PLATE
The most important data regarding use and performance of the welding machine are summarized on the rating plate
and have the following meaning:
1
– Protection class
