1. Description
1.1. Machine construction
The welding machine TT 350MIG/MAG (hereinafter referred to as the source) is
constructed as a power frequency converter (inverter).
Modern principles and knowledge in the field of semi-conductor technology and
controlling electronics have been used when constructing the source. Due to that the
source is characterized by:
- high power at small dimensions and low weight
- high efficiency
- quality welding characteristics
- stability of parameters independent on the electric power voltage variation
Electronic control ensures parameters stability and contains the circuits for the
source protection in case of failure or overload and ensures optimal welding
properties.
The source is designed as a compact mobile machine.
A massive all-metal four-pulley wire feeder with driven feeder pulleys is a standard.
On the front panel there are quick plugs for connection of the welding cables, a euro-
terminal for connection of the welding torch for setting of the optimal welding
parameters for the individual welding technologies, two digital measuring devices and
three LEDs
The source cooling is forced with a ventilator.
1.2. Controls
Positions and names of the individual controls are given in the pictures:
-
pic.1 – front panel
-
pic.2 – back panel
-
pic.3 – feeder panel
Explanation of the individual controls is given directly at setting of the source for the
selected welding processes.
1.3. Welding technology
The source is determined for welding by:
- coated electrode (method MMA)
- method MIG/MAG (it is possible to use Fe wires, including stainless wires and Al-
wire)
- method WIG (arc ignition is made by touching the electrode)
The source power enables to use coated electrodes in range from Φ1.6 to Φ8mm
and wire in range from Φ0.6 to Φ1.2mm
Preparation and control of the source for individual welding technologies are
described in Chapter 5.
