The control panel is in the right side of front panel, it has above electrode arm in the middle of the front-panel, below electrode arm links with welding press platen, and the heat treatment clamp-holder device is at right side of front-panel.

Back of the machine has power switch, fuse tube and foot switch. Foot switch and control panel are parallel connection, it used for start and stop welding, braze welding and heat treatment.

Control panel has mode select button to exchange among spot welding, braze welding, heat treatment, and it has state instruction: dxx means spot welding, q_x means braze welding, h_x means heat treatment. For the working power, it has increasing button and decreasing button for choose.

The above electrode arm has four electrodes, vertical rotate to choose the suitable electrode combination, the below electrode arm also has four electrodes; rotated to choose the suitable electrode combination, so that make up of different sets of electrode combination to adapt various different welding. Furthermore, the electrode revolves 90° can position automatically at each time.

2、Operation method:

⑴Spot Welding operation

Press “(11) mode selection” button choose spot welding, braze welding, heat treatment mode. But please notice that when in the heat treatment condition, the above electrode arm and below electrode arm should be separated.

①Choose suitable electrode combination according to the weldment, check if the electrode was oxidized, and the point of weld should be polished smoothly with sandpaper or polishing file before welding.

② The weldment needs to clean, no oxidization, without greasy dirt.

③ Connect on power supply, turn on the power switch, press the (11) mode selection button to adjust the welding mode as dXX (X=numeral value, same as follows) and choose suitable welding power according to the size of the welding material (following test parameters for reference), press (1) power increase↑button to increase the power, press (12) power decrease↓button to decrease the power.

④ Press down the (7) welding pressure plate, put the demand weldment between the above and below electrodes, then relax the welding pressure plate slowly, make sure the above and below electrodes compressed the weldment tightly. Press (10) Start button or (9) foot switch after confirm the correct welding point. Then it will output energy between the above and below electrodes to welding. After finished output, relax the electrode arms, take out the weldment, and then continue the next welding.

⑵ Heat treatment operation

① Firstly place (13) plastic bracket between above and below electrode arms to separate above and below electrode arms, adjust the machine on heat treatment state through the (11) mode selection button, the display will show h-X.

② According to the diameter and length of stainless wire, and distance of the heat treatment pole, press (1) power increase“↑” and (12) power decrease “↓” to adjust suitable heat power.

③ During Heat treatment condition, the (13) plastic bracket should be placed between above and below electrode arms to separate them, or the machine will have Beep sound and display show “Err” to remind user.

④ Operate the heated clamp holder clip the stainless wire between heat treatment poles, press start button or foot switch, then the heat treatment poles will output energy to heat the stainless wire, release start button (or foot switch) to stop heating. After heated, relax the holder, take out the stainless wire then continue the next heating.

⑶ Braze welding operation

① Choose suitable electrode combination according to the weldment demand, check if the electrode was oxidized, and the point of weld should be polished smoothly with sandpaper or polishing file before operation.

② The weldment needs to clean, no oxidization, without greasy dirt.

③ Connect on power supply, turn on the power switch, press (11) mode selection button adjust to braze welding condition q_X, and choose the suitable power of braze welding according to the specifications of the welding material.

④ Press down the welding pressure plate, wipe soldering fluid between the two welding material, put two welding materials into the above and below electrode, make sure the two welding material was compressed tightly, then relax the welding pressure plate slowly. Press start button or foot switch after confirm the correct position of the welding point. Then it will output energy between the above and below electrodes to welding. Complete braze welding after release start button (or foot switch). Relax electrode arms when finish welding, take out the welding material, and then continue the next welding.

3、Control panel operation:

① In holding state, each time press (1) power increase button (↑), the power will increase 1, the display shows numeral value increase 1, and automatically jump to lower limit value until reach the upper limit.

② In holding state, each time press (12) power decrease button (↓), the power will decrease 1, the display shows numeral value decrease 1, and automatically jump to upper limit value until reach to lower limit.

③ In holding state, each time press (11) Mode selection button, the display will change once among dXX, q_X, h-X. dxx=spot welding, q_X=braze welding, h-X=heat treatment (X= numeral value, same as follows).

④ In holding state, when display screen show dXX means spot welding condition(XX=01-30), make sure no plastic bracket between electrodes, press START button to start welding, long time press start button only working one time.

⑤ In holding state, when display screen shows q_X means braze welding condition(X=1-9), no plastic bracket between electrodes, press START button to start braze welding, relax the button will stop braze welding immediately.

⑥ In holding state, when display screen show h_X means heat treatment condition(X=1-9), place plastic bracket between electrodes to separate above and below electrode arms, press long time START button to start heat treatment, relax the button will stop heating immediately.

⑦ In holding state, ensure current operation mode same as the system mode totally when press START. It means the mode that display shows should the same as operation mode you selected. Or it will show Error and no beep sound, press start button long time, it only working one time.

⑧ Press each button above mentioned; the buzzer will have beep sound.

⑨ If buzzer beeps endless, means it can’t work at present.

4、Announcements:

① Must use the single-phase three-pin power supplies, guarantee that the case of the machine connect to the earths to insure safety.

② Put the machine to the dependable place.

③ Use AC stabilized supply if possible, since it can guarantee the welding power stability, and it can reduce affection to other electric appliance.

④ The electrode must be rotated with clockwise.

⑤ Operate under the welding and heating conditions, according to the operation method, put the plastic bracket in the correct position and adjust the “mode” button correctly, besides, whenever operating in which mode, electrodes and heat treatment poles will output energy at the same time, so during welding, please don’t touch the heat treatment poles, vice versa.

⑥ When the welding power is bigger, or the weld material get in bad connect, please prevent the splash thing burn to human body, the operator must wear protective glasses and protection gloves.

⑦ After finish using, wipe the machine clean, then put it at dry and well-ventilated place that have no causticity air indoor.

⑧ When the machine failure, contact with the factory or professional person in time.
