We used the welding machine is the case, according to start the switch, only the current, arcing sometimes without, before that in the welding machine inside the circuit version of the broken. Now, I don't know what happened this time
The arc ignition circuit is out of order.
The relay is out of order and will only turn on or off normally. This is the case for the high frequency generator. The normal is zero point eight to one point two, usually one millimeter! The best use of fine sandpaper two opposing sides hit high frequency device position can read the instructions, no manual can open the lid to see where there is the fox led arc there, in the process to Caution!, beware of electric shock, welding machine with a capacitor to power off after five minutes of operation
The most likely is that the relay inside is broken, turn on the welder and see the circuit board below the discharge electrode, which has a black square side. With a screwdriver gently knock a few times, and then connected to the power, press the switch on the welding, look at the discharge electrode discharge spark is good, if not, then knock a few times, until the electrode spark. This is only temporary, preferably with a relay.
