5. GENERAL DESCRIPTION
SPARTUS® EasyTIG 203P DC, 205P DC, 208P AC/DC and 210P AC/DC
Modern digitally controlled inverter welding machines, costructed on the basis of IGBTs and
PWM technology. Allows welding TIG and MMA. They are powered with single-phase 230V
source power.
These are devices designed and manufactured in order to fieldwork. Small, light and versatile.
Ideal for welding steel and stainless steels. Built-in pulse welding mode allows you to weld very
thin elements.
Easy-to-use and intuitive function panel allows you to precise control of all most important
welding parameters for TIG DC and MMA DC modes.
The device is equipped with wide range of modern technologies which support operator during
welding or secures device before damage. For example:
MCU control system
– reacts immediately to any changes,
Intelligent protection system
– overvoltage, overcurrent, overheat, when the problems listed
before occurred, the alarm lamp on the front panel will be on and the output current will be cut
off. It can self-protect and prolong the using life,
Contactless arc ignition system HF
– easy and contactless arc ignition in TIG method,
The digital control panel
– easy operation and setting of appropriate welding parameters,
Examples of use: portable repair, workshop, maintenance, light constructions.
5.1. PRINCIPLE OF OPERATION
Single-phase 230V work frequency AC is rectified into DC (about 312V), then is converted to
medium frequency AC (about 40KHz) by inverter device (IGBT module), after reducing voltage
by medium transformer (the main transformer) and rectifying by medium frequency rectifier
(fast recovery diodes), then is outputted DC or AC by selecting IGBT module. The circuit adopts
current feedback control technology to insure current output stably. Meanwhile, the welding
current parameter can be adjusted continuously and steplessly to meet with the requirements
of welding craft.
5.2 PURPOSE OF USE
SPARTUS® EasyTIG 203P DC, 205P DC, 208P AC/DC i 210P AC/DC:
• Tungsten Inert Gas welding (TIG)
• Manual Metal Arc welding (MMA) (SMAW – Shielded Metal Arc Welding).
