Load an electrode in the welding gun and ensure that the electrode clamp is touching the bare metal of the electrode. Turn the welding machine on and make sure you can hear a humming noise from the transformer.
Check the breakers in your circuit box if your welding machine is not getting power. Welding machines draw a large current, and it's not uncommon to trip a breaker. Some welding machines even require a special circuit with a higher power rating.
Strike the arc. Touch the tip of the electrode to the base metal and immediately pull it back to the desired welding (stick-out) distance. You may need to increase the amperage on the welding machine if you have trouble striking the arc or maintaining an arc at the proper stick-out distance.
Adjust the amperage on the welding machine to correct additional welding problems. A weld that is pitted and has deep craters at the edges is a clear indication that you need to reduce the amperage.
