!
Welding power is infinitely variable while welding -- no performance limiting pre-set power
settings
!
Welding power is controlled from the welding handle and can be varied while welding to insure
good weld penetration even when welding materials of varying thickness and structural stability
!
Special controls assist with arc starting by allowing the operator to briefly use high power while
starting an arc and then dropping back to a preset power setting when arc condition is
satisfactory
!
The Backpak welder also features a highly sophisticated electronics speed controls system
which has been designed to insure optimum engine efficiency from the welder’s powerful 2-
cycle engine when welding and when idling at rest
Additionally, your welder includes features which you would expect to find on any high quality
welder:
!
Output power is fully isolated from engine, or earth ground.
!
Weld with both standard and reverse polarity.
However, even our “standard” welding controls are unique -- with power to the welding electrode and
engine speed control automatically activated whenever the welders electrode tip makes suitable
electrical contact with a metal object to which the welders “ground” clamp has been securely
connected. Simply breaking the welding arc will simultaneously shut off welding current and set the
engine back to idle.
