•Turn the input power OFF at the weld- ing power source before installation or changing drive rolls and/or guides.
•Do not touch electrically live parts.
•When inching with the gun trigger, electrode and drive mechanism are "hot" to work and ground and could remain energized several seconds after the gun trigger is released.
•Do not operate with covers, panels or guards removed or open.
•Only qualified personnel should perform mainte- nance work.
The pressure arm controls the amount of force the drive rolls exert on the wire. Proper adjustment of the pressure arm gives the best welding performance.
Set the pressure arm as follows:
