AC and DC pulse square wave argon arc welding machine operation method?
If the black needle tune too close to the outside, a welding is easy to stick, the Ukrainian needle transferred to the porcelain mouth inside 1-2 mm, and then welding will not stick, and welding out of the effect is better.Argon arc welding argon arc welding technology is based on the principle of arc welding on using argon protection for metal welding, the welding material in high current to be welded on the substrate is melted into liquid form molten pool, the metal to be welded and the welding material to a welding technology of metallurgical combination, also known as argon gas shielded arc welding. Argon arc welding is divided into two kinds of argon arc welding and non melting argon arc welding according to the different electrodes. Argon arc welding technology is based on the principle of arc welding on using argon protection for metal welding, the welding material in high current to be welded on the substrate is melted into liquid form molten pool, the metal to be welded and the welding material to a welding technology of metallurgical bonding, due to the high temperature melting on argon welding continuous feeding in the welding material can not contact with oxygen in the air, thereby preventing the material oxidation, therefore can welding stainless steel, iron metal hardware.
Mainly because of your black needle tune too close to the outside, a welding easily stick, the Ukrainian needle into the mouth of the porcelain inside 1-2 mm, and then welding will not stick, and welding out of the effect is better.
This problem can be formed in many ways1. the current is too small2. argon is insufficient or not opened3., the input power line is too small or too long, resulting in insufficient flow4. switch improper adjustment, according to the material needs spot welding, or to blow welding, tune 2T or 4T function [various welding machine function is different, look at several instructions]5., the main problem is more experience, practice there is a touch, and more advice to the bottom of the master6. uniform solder joint without welding wire welding conditions can keep gold. Blue. A word is passed to any white when mixed to 6000 to 1W.RMB per month.7., you choose this function of welding machine is still very wise, two words easy to use...
