Product overview of digital pulse shot cold welding machine LHJ-315S

Preface:

This real pulse shot cold welding machine is composed of three major functions, namely shot cold welding, argon arc welding and arc welding. It is controlled by digital CPU circuit. It has innovative circuit structure and accurate control. Because the machine has many overall control functions, many functions are difficult to be mastered; For example, a series of functions such as air supply in advance, air closing after setting, arc starting current, rise time, peak current, downhill time, arc ending current and delayed air closing make it difficult for ordinary operators to be mastered. Therefore, the engineering designers of the company write the data above functions to the microprocessor, and the user only needs to operate the machine according to several operation keys on the panel. This provides help for the new and old users and the design especially suitable for novices

Operation guide

Open the packing box, take out the welding machine, check whether there is damage and error, turn on the 220V AC power supply and turn on the ship power switch. At this time, the operation panel displays all functions, the digital display meter displays the model and then the serial number (note; Each model has an independent number) and then displays the current current value. When the user adjusts the current current value, the CPU automatically saves the data for the next startup. The local startup priority is set to TIG gear (the indicator light is on), cold welding gear (SW) indicator light is on, pulse gear off (-) indicator light is on, 2T gear indicator light is on, (REM) power indicator light is on and note; Argon gas pipe 16 must be connected during cold welding and argon welding

 

1. Shot Cold welding (SW) is mainly stainless steel welding. Press the light touch switch 5 to adjust the current according to the thickness of the plate. When pressing the current + 1 or - 1 continuously, the number will scroll. Adjust the 1 (s) potentiometer to change the discharge time. The specific application depends on the thickness of the plate and the color of the solder joint

 

2. Argon arc welding (CW) press the operation key 2 to convert to argon arc welding. During welding, only 5 current needs to be adjusted.

 

3. Arcwelding (MMA), press operation key 3 to switch to manual welding mode, and the (HIA) arc striking current indicator is on. During welding, only 5 current needs to be adjusted. At that time, the program will turn off irrelevant functions.

 

4. Pulse and pulse functions are only useful for cold welding and argon arc welding, and arcwelding is invalid. Press the operation key 9, the pulse indicator lights up, and rotate the pulse potentiometer 8 to change the pulse frequency according to the needs of the welding process

 

5. 2Tand4T press the operation key 7, then the 4T light is on, and this function is applicable to automatic welding Note: Cold welding and manual welding are invalid

When the machine temperature is too high, the fault indicator C.O is on when it exceeds 75 degrees. At this time, the CPU control output and the digital display meter displays EP08 code

 

WSME-280 Digital pulse AC and DC welding machine product overview

Preface: This model has 3 major functions, namely AC argon arc welding, DC argon arc welding, and DC arc welding. It is controlled by a digital CPU circuit. It has large functions and a new modular design. The circuit structure is simple and the control is accurate. Due to the overall control function of the machine Many and many functions are not easy to master, such as early air supply, rear air closing, initial current, uphill time, peak current, base current, operating frequency, downhill time, vertical arc current, delayed air shutdown, etc. The function makes it difficult for ordinary operators to master, so the company’s engineering designers write the above functions to the microprocessor to complete, the user only needs to operate according to a few operation keys on the panel, which provides help for new and old users, which is especially suitable for novice welders.

Operation guide

Open the packing box and take out the welding machine to check for damage. After it is correct, turn on the 220V AC power supply and turn on the ship power switch. At this time, the operation panel displays various functions, and the digital display shows the model, and then displays the serial number (Note; each model There is an independent number) and then the current current value is displayed. When the user adjusts the current current value, the CPU automatically saves the data for the next startup. The machine is turned on and set to the TIG file (the indicator light is on) and the AC file (AC) indicator light is on and pulsed. The off gear (-) indicator light is on, the 2T gear indicator light is on, and the (REM) power indicator light is on. Note; the argon gas pipe must be connected during AC argon arc welding and DC argon arc welding. 16

 

1. AC argon arc welding (AC) is mainly based on aluminum welding. According to the thickness of the plate, press the touch switch 5 to adjust the current size, press the current +1 or -1 continuously when the number is scrolled, and adjust 1 (%) The potentiometer changes the cleaning width, depending on the board

 

2. Direct current argon arc welding (DC) press the operation key 2 to switch to argon arc welding, and only need to adjust the current of 5 when welding.

 

3. Manual welding (MMA), press the operation key 3 to switch to manual welding mode, at the same time (HIA) the pilot arc current indicator light is on, only need to adjust the current value of 5 when welding, then the program will turn off irrelevant functions.

 

4. Pulse and pulse functions are only available for AC argon arc welding and DC argon arc welding, but manual welding is invalid. Press the operation key 9 the pulse indicator light is on, and the pulse potentiometer 8 is rotated according to the welding process to change the pulse frequency

 

5. Press the operation key for 2T, 4T. 7 At this time, the 4T indicator light is on. This function is suitable for automatic welding and injection; manual welding is invalid.

 

6. When the temperature of the machine is too high, the fault indicator O.C is on when the temperature exceeds 75 degrees. At this time, the CPU controls the output and the digital display shows the EP08 code.
