TOPWELL industrial mma welding and gouging power source mma welding machine ARC-400i/500i

1.Arcforce rotary dial
To adjust the welding parameters to the
electrode type used. Infinite setting from rutile
(soft arc) to cellulose (hard arc) electrode types.
2.Hotstart current rotary dial
Increased ignition current during the set hotstart
period to optimise the arc ignition.
3.Welding current setting rotary dial
Infinite setting of the welding current across the
whole power range.

Hot start function reliably ignites the electrode and melts
perfectly to ensure the best quality even at the start of
the seam. This solution makes lack of fusion and cold welds
a thing of the past and significantly reduces weld reinforcement.
Adjust the hot start current here and the time here.
