airarc takes 250 amps to run 1/4 rod the more volts the better air pressure 90psi and up it will burn most anything including you

80-100 psi is fine.Electrode positive(reverse polarity)Make sure to have air holes down(between work and electrode)Force electrode into work softly,in such a mmanner as its not really touching metal,move forward slowly.

air preasure; 80-100psi is fine.make sure to have the air holes between electrode and material(down). use reverse polarity(electrode positive)hold at approx. 30-60 degree angle.use very light force ,light not really touching material.proceed at slow even rate.

Set the air pressure for whatever the specs call for on the equipment you have, put the amps at 100 or so to begin with, and experiment on some scrap steel before trying to do anything critical. Aim it away from you at a 45 degree angle to begin with, and strike an arc as if you were going to weld. Be sure to cover every square inch of yourself with protective gear, and don't do this in the vicinity of flammable materials of any kind! These things work, but boy do they put sparks and hot metal into the air!
