HT MAPPRO GAS

Product Introduction

Product use: Specially designed for copper tube welding, soldering, and rapid defrosting in the refrigeration industry. The specialized welding gun used in conjunction can achieve a heating temperature of 1960 degrees Celsius or higher when supported by oxygen Commodity characteristics：
1. Safe, convenient, professional, and concise.
2.Under oxygen assisted welding conditions, the combustion temperature of HT MAPPRO GAS can reach above 1960 ℃.
3.Easy to weld with one hand, convenient to carry.
4. Scientific mixing ratio and good flame characteristics ensure welding effectiveness and shorten working time.
5.Under normal working conditions, it can achieve a continuous combustion time of more than 2 hours and 30 minutes.
6. A special professional mixed gas designed for a large amount of soft/hard welding work, such as copper pipe welding during the installation of heating and cooling equipment.
Usage method:
1. Remove burrs from the copper pipes that need to be welded. Then measure the diameter of the copper tube and select a suitable specialized welding gun based on the diameter of the copper tube to be welded.
2. One end of the copper pipe that needs to be welded is expanded.
3. The welding gun is installed on the MAPP cylinder. Method: the top needle of the welding gun is aimed at the center part of the MAPP cylinder connection, so that the screw position of the welding gun is aligned with the screw port of the cylinder, and the cylinder is rotated against clockwise until tightened. Avoid screw thread misalignment, damage the thread, the position of the welding torch is not installed, the interface will leak, and it will cause danger when igniting.
4. Before ignition, the cylinders need to be shaken several times, so that the additives in the bottle and liquid gas can be fully mixed.
5. Gently rotate the regulating valve on the welding gun until a slight "sizzling" outgassing sound is heard, the ignition button (self ignition welding gun T-A) is pressed down and the adjustment valve is opened to the maximum abandonment position after the ignition. At this time the flame is very long, the gas is sprayed fiercely, the strong "hissing" sound, and the shape of the flame. It's scattered. This flame is not the flame we need to weld normally. Back to the adjustment valve, it can beseen that the shape of the flame shrinks gradually. When the flame shrinks to the depth of blue, the gas is most fully burned at about 1.5 cm. The flame is most suitable for welding at this time.
6. When heating, the distance of the muzzle is about 1.5 centimeters, burning copper tube until bright red, the time takes about 10-20 seconds (the heating time depends on the ambient temperature in the summer, the welding small copper tube is heated to the required temperature of only 5 seconds) and then the electrode is aimed at the spot where the welding is required. The electrode will melt into the weld immediately and operate until the whole weld is welded.
7.In the long time uninterrupted welding, the MAPPRO gas pressure in the bottle will be lower than the normal level because the temperature of the bottle can be greatly reduced (showing the bottle body sweating), and the temperature of the cylinder needs to be suspended and then used again.
Use of knowledge:
1.Keep the thimble and sealing surface of the welding gun clean and avoid damaging the sealing effect due to dirt.
2. When it is found that there is a leak in the connection between the cylinder and the welding torch, please do not ignite. The torch should be rolled out and the cylinder should be returned to the distributor for examination.
3.When firing, the muzzle should be directed against the unmanned area, and no flammable and explosive items should be placed around it.
4.MAPP gas should be kept in a cool place at ordinary times to avoid direct sunlight and avoid violent collisions, so as to prevent damage caused by packaging containers.
5. In the event of a fire caused by leakage, the tank and welding gun can be directly covered with a wet cloth or yellow sand, the air is extinguishing, and the fire extinguisher can be used to direct the fire extinguishing.
