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 workei 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.
When switching to MIG process, the welder can use 2T or 4T torch latch function for
Stainless Steel, Iron welding.
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:^ 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
5.2.3 Attenuation parameter adjustment:When completing a section of welding and ending the arc, in order to ensure good forming, the current is required to gradually decrease
to stop. This parameter is used to adjust the decay time of the current.
Note:When using the "foot pedal" control, this knob is turned counterclockwise to "0"
5.2.4 After flow gas time parameter adjustment:The workpiece after welding is oxidized by the heat, so after the welding is stopped, the argon gas blown by the welding torch is
used for a certain period of time. This parameter is the time after the exhaust gas is adjusted, and the maximum time can be 10 seconds.
5.2.5 In "MMA" mode,only the welding current, the hot start, arc force, and other functions do not work.
5.3 Indicator light
Overheat protection indicator: When the welder is working continuously, for a long time or at a high current, the overheat protection function is set to prevent damage to the
device due to internal heat. When the light is on, the digital display shows -E2, stop working, but not Shut down, after about 2-3 minutes the device can be automatically
restored.
