Mfdc Carbon Brushes AC 25kVA Automotive Spot Automatic Tank Machine Welding

MFDC spot welder Main Features

(1) Advanced electronic parts and IGBT inverter technology are used to content the welding material of multi-layer steel plate, alloy, coated steel plate, aluminum alloy plate, bolts ,car body high-strength steel plate,
stainless steel and galvanized sheets, which is hard to weld by AC resistance spot welder.
(2) DC inverter welding technology use single direction current heating. Welding current can be easily controlled to form multiple current waves,in order to get high welding quality.
(3). Quick response of current control and adjustable electrode pressure functions is applicated 
to fullfill special welding craft.
(4). Minimized welding transformer and Medium Frequency Inverter techonology can save electricity 35%.
(5). 3-phase loads balancing with high power factor have no impact on power supply transformers.
(6)At the same time, the impact on the power grid is very small, even in the case of high-power rapid welding will not affect the power grid;
(7)The electrode life can be more than doubled, and the electrode grinding time can be reduced;

Frequency inverter spot welder Has the following advantages compared to with 50 Hz ordinarytraditional welding:

1,Is the current international advanced resistance welding products;
2,Low operating costs;
3,Three-phase power balance input power factor is as high as 95%;
4,Secondary loop almost no induction energy loss;
5,Low welding current and pressure;
6,About energy more than 20%;
7,Greatly save water and electricity installation, gas and otherauxiliary facilities installation cost;
8,More accurate, more rapid and more comprehensive control and
analysis of welding parameter;
9,Shorter welding time and improve production efficiency.
10,Used in most of the metal material welding effect will be better,especially in the welding of aluminum, aluminum alloy and high thermalconductivity of copper and other metal effect is better, more stable andreliable quality.

1. Q: Water leakage on welding wheels and transformers?

A: The plug of the transformer connection waterway is not tightened.

2. Q: Device does not turn on?

A: The neutral line of the device is not connected.

3. Q: Excessive sparks from equipment splash?

A: Increase cylinder welding pressure, electrode dressing, sample surface should be flat and free of dirt.

4. Q: Galvanized sheet welding sticky electrode?

A: Replace the welding machine electrode head material is alumina copper, alumina copper is resistant to high temperature, and it is not easy to cause adhesion to the zinc layer on the surface of galvanized sheet.
