A continuous load current rate of welding and welding cycle than access time. =t/T*100% loading rate is sustained, "t" for the welding current access time "T" for the entire period (the sum of working hours and rest periods) cycle 5 minutes.

Third. The adjustment of welding current

Welding current regulator for the two tranches, Ⅰ, Ⅱ followed by the combination of two tranches for a complete switch. Fine adjustment of welding current rotation on the handle conditioning coil position, and change the size to achieve leakage reactance.

Fourth. The attention

1、Pre-operational check carefully whether the nut tightening wiring, grounding grounding line reliability.

2、The welding process, seeking Combined Switch shift, we must stop welding, the welding process must not shift!

3、The use of welding, the welding machine welding current than allowed welding value.

4、Welder not by rain, snow-drenched, should be placed on a dry place.

Fifth. BX3 series welding machines and methods to Common

Fault

Why cause

Elimination

Lead superheated Connection

Connection contact resistance is too big wiring Department ban firmware is too lax.

Loose wiring, use sandpaper or a knife Department will contact conductive metallic sheen sorted out, then screw screw or nut ban.

Welder overheating

1、Transformer overload

2、Transformer short-circuit

3、Core screw insulation damage

1、Reducing the use of current, in accordance with the regulations load operation;

2、The elimination of short-circuit;

3、Recover insulation.

Electrical shell welder

1、Primary or secondary winding winding collision shell;

2、The power line collision shell;

3、Welding cable collision shell;

4、Grounding not or grounding bad.

1、Check and eliminate collision shell;

2、To eliminate collision shell;

3、Eliminating collision shell;

4、And then make good contact with a good grounding line.

Welder insufficient voltage

1、The secondary winding is short;

2、The low voltage power supply;

3、Power lines are too thin, too much pressure drop;

4、Welding cable is too small, too much pressure drop;

5、Bad contact.

1、The elimination of short-circuit;

2、Adjust voltage to fixed value;

3、The replacement of thick line supply;

4、The replacement of thick cables;

5、To make good contact joints.

Welding current is too small

1、Welding cables is too long ;

2、Welding cable disk into two types, large inductance;

3、A cable joints or to the workpiece is not good.

1、Or to increase the length of the cables to reduce cable diameter;

2、Cables from the disk should be open;

3、Joint good contact, contact with the workpiece good.

Welding current instability

Have access to the workpiece and welding cables is not good.

Welding cables make good contact with the workpiece.

Welder output current is unusual, too large or too small.

1、The circuit plays the role of the inductive loop coil insulation damage caused excessive current;

2、Core alternating Whirlpool insulation damage caused Current too small.

1、Circuit insulation inspection, troubleshooting;

2、The magnetic circuit insulation inspection, troubleshooting.

Welding strong ring for buzzing

1、Secondary coil short- circuit;

2、Sub-circuit current, or use too much overload.

1、Check and eliminate short-circuit;

2、Check and eliminate short-circuit, reducing the use of current and avoid the use of overload.

Welder is not the normal noise

1、The safety net by the electromagnetic vibration;

2、Box screw loose shell;

3、And side cover after cover the latter;

4、Machine screws, nuts loose.

1、To check the noise and vibration;

2、tightening screw shell boxes;

3、Check and eliminate the latter;

4、Opened the side cover screening and tightening screw nut.

Fuse broken

1、The latter joint power line;

2、Short-circuit electrical wiring joints collision shell;

3、Broken power lines joint ground.

1、Check and eliminate short-circuit;

2、Check and eliminate short-circuit;

3、Replace or repair power lines.
