DESCRIPTION

Your new MIG (Metal Inert Gas) wire feed

welder is designed for maintenance and sheet metal fabrication. The welder consists

of a single-phase power transformer, stabilizer, rectifier, and a unique built-in control/feeder.

Now you can weld sheet metal from 24 gauge up to 3/16 inch thick with a single pass. You can weld thicker steel with beveling and multiple pass techniques. Table 1 lists your MIG welder specifications.

MIG welders equipped with gas are capable

of welding with 0.024.(_0:6mm) and 0.030 (0.8mm) solid steel wire on dc reverse

polarity and with 0.030 (0.8mm) self-shielding flux-core wire on dc straight polarity. Larger, 0.035 inch (0.9mm) diameter solid steel wire, on dc reverse polarity may also be used on this welder. The use of larger diameter wire makes welding difficult and the results cannot be guaranteed. Use of

larger than .035 diameter wire is not recommended.

WELDER OPERATING

CHARACTERISTICS

DUTY CYCLE

The duty cycle rating of a welder defines how long the operator can weld and how long the welder must be rested and cooled. Duty cycle is expressed as a percentage of 10 minutes and represents the maximum welding time allowed. The balance of the 10-minute cycle is required for cooling.

Your new welder has a duty cycle rating of 40% at the rated output. This means that you

can weld for four (4) minutes out of 10 with the remaining six (6) minutes required for cooling. (See Table 2).

INTERNAL THERMAL

PROTECTION

CAUTION

Do not constantly exceed the duty cycle or

damage to the welder can result. If you exceed the duty cycle of the welder, an internal thermal protector will open, shutting off all welder functions except the cooling

fan. If this happens, DO NOT SHUT OFF THE WELDER. Leave the welder turned on

with the fan running. After cooling, the thermal protector will automatically reset and the welder will function normally again. However you should wait at least ten minutes after the thermal protector opens before resuming welding. You must do this even if the thermal protector resets itself before the ten minutes is up or you may experience less than specified duty cycle performance.

If you find that the welder will not weld for two minutes without stopping, reduce the wire speed slightly and tune in the welder at the lowest wire speed setting that still produces a smooth arc. Welding with the wire speed set too high causes excessive current draw and shortens the duty cycle.
