3.MACHINE DESCRIPTION
The welding machines are rectifiers adopting the most advanced inverter technology, which can
apply in plasma cutting system of using pressing air.
The development of inverter welding equipment benefits from the development of the inverter
power supply theory and components.
3.1
CT series welding machine is the latest multi-purpose machine developed by our company. It
is suitable for all kinds of metal cutting machines, argon arc welding and manual arc welding. Its
biggest feature is that it can cut stainless steel, alloy steel, carbon steel, and other non-ferrous
metals with cutting function, or it can weld stainless steel and carbon steel products with DC
function. For example: for the welding of scooters, bicycles and other products.
3.2
CT series welding machine is also based on our company's unique high-frequency inverter
technology, compared with the traditional machine, small size, light weight, high conversion
efficiency, energy saving; Compared with imported machine, cheaper, more adaptable to power
grid. To highlight the use of two inverter technology, the pure square wave output, so that the
arc stiffness is good, heat concentration, reverse cleaning ability, wide cleaning range, small
current is not easy to break the arc, etc., to ensure the excellent welder Welding characteristics.
3.3
The welding machine is also equipped with a foot pedal current regulating device, so that the
welder can free the hand to adjust the current with the foot; thus, the current can be quickly
heated when the welding is initial and the wire is added, and the current is reduced at the end of
the welding. Welding pattern formation; the use of the pedal helps to improve welding efficiency,
reduce welding difficulty and ensure welding quality.
WARNING
！
The machine is mainly used in industry. It will produce radio wave, so the worker
should make fully preparation for protection.

5.PANEL FUNCTION INSTRUCTION
5.1 Button function
Option function button: When the function button is selected as “CUT” mode or the indicator
light is CUT, it can cut the iron plate for the cutting function; when the function button is set to
“TIG” mode or the indicator light is for TIG, it is DC argon arc welding. It can weld stainless steel,
iron, copper and other metals.
MMA/CUT/TIG function button: it is manual melt arc when the function button selected as
“MMA”.
5.2 Parameter adjustment (by the arrow button)
5.2.1 Pre-flow gas time parameter adjustment:In order to ensure the welding effect, argon is
required to arrive earlier than the current during welding. This parameter is to adjust the
interval between the argon out and the arc.
5.2.2 Current adjustment: it is welding current
