intended to avoid incorrect device operations that could result in serious personal injury or property
damage.
2. GENERAL INFORMATION
SWT2033 welding machine adopts the latest pulse width modulation (PWM) technology and
insulated gate bipolar transistor (IGBT) power module, which can change work frequency to medium
frequency so as to replace the traditional hulking work frequency transformer with the cabinet
medium frequency transformer. Thus, it is characterized with portable, small size, light weight, low
consumption and etc.
The parameters of SWT2033 on the front panel all can be adjusted continuously and steplessly, such
as start current, crater arc current, welding current, base current, duty ratio, upslope time, downslope
time, pre-gas, post-gas, pulse frequency, hot start and arc force etc. When welding, it takes high
frequency and high voltage for arc igniting to ensure the success ratio of igniting arc.
1.For MMA, polarity connection can be chosen according to di erent electrodes.
2.For DC TIG, DCEP is used normally (workpiece connected to positive polarity, while torch connected
to negative polarity). This connection has many characters, such as stable welding arc, low tungsten
pole loss, more welding current, narrow and deep weld.
3.DC Pulsed TIG has the following characters: 1) Pulse heating. Metal in Molten pool has short time on
high temperature status and freezes quickly, which can reduce the possibility to produce hot crack of
the materials with thermal sensitivity. 2) The workpiece gets little heat. Arc energy is focused. Be
suitable for thin sheet and super thin sheet welding. 3) Exactly control heat input and the size of the
molten pool. The depth of penetration is even. Be suitable for welding by one side and forming by two
sides and all position welding for pipe. 4) High frequency arc can make metal for microlite fabric,
