It is as other electrical appliances, welding machines also deals with unvoidable problems and malfunction. In case it is simple failures, you can fix immediately without going to shop for reparation or warranty that can make your work interruped. Some popular problems, causes and solutions about welding process below :

1. Weak welding machine:

- Adjustment of the welding currents incorrectly. »» »» Turn the steering wheel to increase welding power clockwise.

- Input wire is too small. »» »Replace the other wire with larger diameter as instructed (with 1mm² of copper wire under 5A loading).

- Poor electrical connection. »Tighten the bulbs from source to machine to ensure tightness.

- Power supply under 220V »» »» Max rotation wheel to increase the current to compensate for the loss. If it is not enough that you often have to work in a low voltage environment, you should choose a type of secondary pile welding machine to use when the voltage is low.

- Pulling the welding machine too far from the circuit breaker to reduce the voltage. »» »If it is mandatory to pull the machine far from the power supply more than 15m, the use of a larger wire than usual to avoid voltage drop.

- Voltage of current is adequate but still not welded. - Generator power is not enough for welding. »» »» Change of welding power.

2. Electric welding is too strong:

- How to adjust the output line is not correct »» »» Turn the steering wheel counter-clockwise to reduce the welding current.

- Input voltage is greater than regulation »» »» Adjust the source voltage (if possible) or replace with other suitable source

- Welding machine has too large capacity, has been adjusted to the lowest level but still not welded (especially with thin iron) »» »Replacement welding machine with lower capacity.

3. Welding machine emits a loud croak:

- Do not open the case. »Check the tightening of the housing.

- Machine spilled during transportation. »» »» Get to the service station because you can not check exactly the damage inside the machine.

4. Touch the cover (leaking power):

- Machine is humid, metal dust stick to the machine »» »» Metal dust blowing by air compressor, drying machine then bring the machine to the warranty station to re-measure the insulation and the best way to overcome.

- Connection of wire does not properly touch »» »» Check the joints, if it is loose, tightening the bolts but not touch the shell.

- Impact welding machine inside the gut. »» »Must be brought to the station to repair

5. Burn into black at electrical connections:

- The bolt contact points are not tightened. »» »» Clean the black points by sandsheet, then tighten them. In case the black points are badly damaged, the machine should be brought to the service station to replace the contacts.
