Welding Hints and Maintenance
• Always weld clean, dry and well prepared material.
• Hold gun at a 45° angle to the workpiece with nozzle about 1/2" from the surface.
• Move the gun smoothly and steadily as you weld.
• Avoid welding in very drafty areas. A weak, pitted and porous weld will result due to air
blowing away the protective welding gas.
• Keep wire and wire liner clean. Do not use rusty wire.
• Sharp bends or kinks in the welding cable should be avoided.
• Always try to avoid getting particles of metal inside the machine since they could cause short
circuits or other damage.
• If available, use compressed air to periodically clean the hose liner, especially when changing
wire spools.
IMPORTANT: Disconnect from power source when carrying out this operation.
• Using low pressure air (3/5 Bar=20-30 PSI), occasionally blow the dust from the inside of the
welder. This keeps the machine running cooler. Note: do not blow air over the printed circuit
board and electronic components.
• The wire feed roller will eventually wear during normal use. With the correct tension the
pressure roller must feed the wire without slipping. If the pressure roller and the wire feed roller
make contact when the wire is in place between them, the wire feed roller must be replaced.
• Check all cables periodically. They must be in good condition and not cracked.
