FeaturesMake welding simpleVariable MIG Setting Synergic MIG Setting: provides communication between the power source, feeder, and torch--allows for automatic change of the voltage & wire feeding speed by adjusting the amperage or thicknesses. Easy works with new welders or users. Manual MIG Setting: meet the need of an experienced and professional welder by adjusting the voltage & wire feeding speed separately.Aluminum MIG Welding Aluminum MIG Welding (SPOOL GUN need purchasing separately) Capable of welding aluminum by using 100% argon. 1. Graphene feeding liner with regular MIG torch with synergic MIG control 2. Spool gun with manual MIG control. Recommend aluminum welding wire(1lb): Silicon aluminum ER4043 and Magnesium aluminum ER5356 welding wire.DC Stick Weld/Lift TIG DC Stick Welding Smooth welding.Capable of welding with 7018/6011 electrodes.Electrode up to 1/8" 110V, 5/32" 220V. Apply to 9/64" thick carbon steel 110V, 13/64" 220V. (Accessories for TIG welding-TIG torch and tungsten not included. Recommend to use YESWELDER WP-17V-35 TIG torch.)Panel 1. Selector Button； 2.
