The Jiali MIG-130 is a single phase compact power source designed specifically for handymen. The operator only needs to adjust a power setting for the thickness of mild steel to be welded and he's ready to weld. One knob adjusts wire feed speed. Max output of 130 amps allows you to weld up to 3.0mm steel with flux cored wire. Built-in contactor eases use and is an excellent safety feature which makes wire electrically 'cold' until trigger is pulled. Durable feed head with quick-release drive roll tension lever provides positive feed with adjustable tension plus easy accessibility to thread new wire.
